Developments in Motorized Kayaks

This article examines the latest developments in motor kayaks, and what these developments mean for anglers.

Origins of the motor kayak

As kayaks became increasingly popular among anglers, some of them started ‘rigging’ (outfitting) their kayaks with electric trolling motors. The need for doing so arose from the fact that paddling alone was insufficient in many ways – Monohull (common) sit-in and SOT kayaks are excessively wide, heavy and sluggish to their very inefficient design [¹], and paddling them to longer distances in not a possibility that’s offered to most people, especially in adverse conditions such as wind and current.

Typically, the motors used for this purpose were weak (30 lbs to 50 lbs thrust) trolling motors, powered by a 12 Volt lead-acid, deep-cycle marine battery. To this day, this is still a popular setup, and it stayed so thanks mainly to its low cost.

In this sense, kayak fishing, which started as a human powered sport, joined other forms of fishing from small craft, namely canoes, dinghies, etc.

More power and less weight: Lithium-Ion batteries

The advent of Lithium-Ion (Li-On) batteries [²] with their more effective power to weight ratio has added to the appeal of the electric motorized fishing kayak, and as these batteries became more affordable, they contributed to the spreading of motorized kayaks as yet another fishing platform in the market for portable vessels. However, besides their high price, these new batteries still present a problem to the user, and it is the fact that the amount of energy they store is still no match for the energy stored in gasoline, which powers internal combustion engines, namely outboard gas motors, or simply “outboards”.

As much as manufacturers of both kayaks and electric motors taut solutions based on the new Lithium-Ion batteries as the eco-friendly and quiet equivalent to motorboats, the fact of the matter is that they don’t compete well, at least when power and range of travel are concerned. Simply, the numbers are not there.

SOT Fishing kayaks with integrated electric motors – “Motor Kayaks”

In recent years, a growing number of kayak manufacturers has been offering fishing kayaks designed especially to work in a motorized mode, with an integrated electric power drive. Typically, the electric motor is inserted in a special compartment in the middle of the kayak, under the area where the user sits, and the propeller rotates under the hull. This design is not effective in more than one way, starting from the fact that it exposes the propeller to unwanted encounters with vegetation that can make it stall, and hard underwater objects and structures that can damage it. This makes such motor kayaks rather useless in shallow water and/or in water where vegetation abounds. To say that this defeats the purpose of kayak fishing may not be an overstatement. On top of this acute mobility problem, the location on the propeller under the kayak’s midsection makes it ineffective for steering, and forces the user to steer with a paddle and/or with a rudder system that adds unwanted complexity and clutter to a small vessel whose deck is already characterized by much clutter and too little workplace and comfort.
No wonder these big ticket and rather lame motor kayaks haven’t become popular.

A few words on the basic problems of matching motors and kayaks

Typically, common kayaks feature an elongated hull that’s pointy on both ends, and a cockpit that allows their user to sit in the middle of the deck. However, when small motors are concerned, having the user, namely the driver operate the motor from a close distance presents a major advantage in terms of safety, comfort, convenience and steering. For example, canoes, which feature hulls that are similar in shape to kayaks, are offered as paddling canoes with pointy front and rear ends, and square-end canoes where the transom is straight rather than pointy, and allows for mounting an outboard motor and for the driver to sit close to it.

Having the driver of a motorized kayak sit in the middle of the boat and operate a motor that’s several feet behind them doesn’t work well, and in case of an outboard (gas motor), it doesn’t work at all, despite attempts from a few kayak manufacturers to create demo videos that would give the impression that it does….

‘Hybrid’ fishing kayaks designed for motorizing

A couple of manufacturers of extra-wide hybrid fishing kayaks have tried to offer models designed especially for effective motorizing. The special thing about these models is that similarly to square end canoes, they feature a straight transom instead of a pointy rear end. The width of the transom varies, and in the models that feature a very wide transom, it makes the kayak fall outside the designation of kayak, per US Coast Guard regulations.
In any case, even hybrid kayaks (namely hybrid kayak / canoe) with an extremely wide transom don’t work as well as square end canoes, because unlike canoes, kayaks do not offer much in terms of free board, and as soon as the kayak’s rear is loaded with a motor and a driver, and it starts moving in the water with its front end pointing upward, its rear end sinks considerably and becomes too exposed to flooding for safe driving. And this happens even while driving on flat water, let alone in choppy water and waves.
Which is why these days the manufacturers of these kayaks are more low-key about them…

Pedaling anyone? (Just a side note)

In their eternal quest to differentiate themselves from the competition and stay relevant, kayak manufacturers end up offering new designs and solutions that are highly similar to each other. This happens not just in motorized kayaks, but in the market for pedal driven kayaks as well. And while pedal drives for kayaks are not within the scope of this article, it’s worthwhile to mention them since some vendors promote the fallacious notion that pedal kayaks could be an alternative to motorizing, although they certainly cannot, and they don’t even come close, at least when the real world and real people are concerned.
To simplify the ergonomics that apply to pedal drives and to human power in general, an average adult kayaker who is neither old nor impaired can produce around 75 Watts, namely 0.1 Horsepower (HP) at a sustained mode, and only for a few hours. In comparison, the smallest outboard gas engine available today, which is the Honda 2.3, can deliver over twenty times more power, and 6 HP outboard motors that some Wavewalk S4 owners use can deliver up to sixty times more power… and all outboards can run as long as there is fuel in their tank.
Are more words on this subject necessary?

Kayaks with jet drives

These specialty kayaks have been around for two decades, and they have not become popular although their performance in speed terms is impressive. The reason for this lack of market success is not just their price. It is the combination of the fact that they are still just SOT and sit-in kayaks, and this is not a good reference in terms of comfort and load capacity. Besides, jet drives don’t work that well in shallow water, where they can get clogged rather easily. In addition, unlike outboard motors that can be conveniently and inexpensively serviced by professionals at thousands of locations nationwide, proprietary jet drives are hard to fix, and fixing them requires support from the manufacturer, which is expensive and inconvenient.

“Kayak on steroids”

A heavy motorized board described by its manufacturer as a “kayak on steroids” and offered by them as a skiff for a solitary passenger is worth mentioning too, if only due to the fact that it relates to fishing kayaks, despite the fact that paddling it is harder than paddling most barge kayaks out there, namely the very big ones that are excessively wide and heavier than some dinghies. As this craft’s own owner’s manual states, it doesn’t work very well in choppy waters, and it shouldn’t be manned by more than one person. At 150 lbs without a motor, it is not a car-top boat, and it’s not a solution for anyone who doesn’t like to get wet while they engage in fishing or boating.
Enough said.

Fishing kayaks with outboard motors

What is the advantage of outboard gas motors?
As previously mentioned in this article, an outboard gas engine is the only type of propulsion that delivers sufficient power to allow for a kayak to go fast in all kinds of water, to run all day, and to travel for long distances. In other words, it’s powerful and reliable, and therefore safer and more fun.

YouTube features some videos of SOT kayaks outfitted with outboard gas motors. Some of these kayaks are outfitted with an outrigger, because unlike in YouTube, in the real world, SOT kayaks, including big ones, are not stable enough to be driven with outboard motors. Either way, the result is rather pathetic, and makes the viewer wonder about whether our species really deserves to be called Homo Sapiens, namely wise man… The drivers of such kayaks are noticeably uncomfortable, and in most cases wet as well. Not a pretty sight.

Practically speaking, Wavewalk kayaks are the only kayaks that offer full functionality and high performance when powered with outboard gas motors. This is why the company labeled its two bigger models skiff and portable boat. Indeed, they perform perfectly as such, and even better, be it in terms of stability, ease of use, comfort in driving, comfort to the passengers, dryness, load capacity, mobility, speed and seaworthiness.

 

The Wavewalk is a patented invention, and it can be described as a compacted catamaran that features the saddle-seat of a personal watercraft (PWC) also known as jet-ski. This unique combination creates the most stable hull while offering the driver and passengers to balance themselves intuitively and effortlessly, in the most effective way possible.
The result is a boat that punches way above its weight in terms of performance, to a point that it rivals much bigger boats.
And indeed, some anglers and other fishers use their S4 instead of much bigger boats that they used to have before.
For example, this crew of two shrimpers used an 18 ft skiff before they switched to the S4:

 

Motorizing options for Wavewalk kayaks are not limited to conventional outboard motors. In fact, it is possible to outfit the S4 with powerful surface-drive motors (a.k.a. mud motors), and by doing so, enhance their mobility and enable their users to go through very shallow water (“skinny water”), rocky streams, and water with abundant vegetation, such as lily pads, grass, and seaweeds.

And let us not forget paddling, because the ability to propel a motor kayak with paddles as an alternative or complementary mode of propulsion is very important, to a point where it may be critical in certain situations, such as launching and beaching in tough spots, going in very shallow water where a boat could get stranded, especially at low tide, going through weeds, and in case something else prevents the motor from working.

How much HP for my S4 skiff’s outboard motor?

Motorized Kayaks

Wavewalk S4 with 2 HP Honda outboard in strong wind, lake Simcoe, Ontario, Canada

By Pyt Rotary

Ontario, Canada

Lake Simcoe is a 280 square mile lake in Ontario.

12km/h [7 mph] with Honda 2Hp against wind of 24km/h [15 mph]

Lots of fun except my rocky mistake to not have enough gas with me.
I got excited and let the boat run for 15km straight into the lake and realize I am out of gas.
I paddled back half the distance and got gas from shore.
Now I know… From now on I will carry enough gas with me.
Luckily I paid with just one blister on my hand.

I did come back at night and feel SUPER SAFE in it.
It is a great, fantastic boat.

 

(added comment) –

The S4 is SUPER, SUPER, SUPER stable. It does not sway at all.
I have been in bigger boats with V shape hulls.
Those boats don’t have the same stability on the water as the S4. The waves hammer them straight in the teeth.
The catamaran design cut the waves like a knife cuts through butter.
Definitely there is room for more HP on the S4.

It was my fist ever trip with a gas motor, I do use W500 with an electric motor but never played with gas before. Lots of fun. Now I can reach easily lots of my fishing spots.
Regards from Ontario, Canada.


(added later) –

After 7 years of tests I think I found the best way to store the rods on Wavewalk, at least for me.

The challenge was in S4 where drilling on the back side where the gas engine reside is not much appealing to me.
So what I did was to buy 2 Homer Tool boxes from Home depot $10 each and use the box to store dry different items at the tip of the S4.
The end of the fishing rod where the reel is, rests on the box and the tip is secured on the upper side of the kayak with sticking Velcro (same Home Depot).

I had some exist on water testing and I can carry easily 4,5 fishing rods in S4.
Since I like the concept I start to think how I can fit that in W500.

I got 2 plastic rings from dollar stores (shower curtains rings) and secure them with a round screw inside the tips on back side under the transom. The handle of the rods rest inside the rings, the tip of the rods is secured by same sticking Velcro in front of W500. 2 rods can be stored easily inside a W500 this way.

Now I am still in doubt to install the same rings in S4 as well since the setup is so successful for me in W500. I will still used the Tool boxes as storage (2L of gas, gloves, tackle, ropes, anchor).

Testing 15″ short (S) shaft outboard motor performance with Wavewalk kayaks and boats

This article summarizes the research that Captain Larry Jarboe, of Florida Fishing Kayaks and Boats in Key Largo, Florida did on this subject, and we are very grateful to him for this exceptional contribution.

Background –

 

Larry’s main goal in conducting this series of experiments that lasted for several weeks was to find the “sweet spot” for 15″ (S) outboards, namely a setup that would enable him to successfully outfit W500 and W700 boats with such motors, which are typically cheaper and easier to come by than 20″ (L) motors.
His secondary goal in running these extensive tests was to check the performance of Wavewalk’s TMM 700 HD motor mount, and see if we could improve it.

Larry is a passionate fisherman, mechanic, and seaman. He works as a commercial fisherman and fishing guide, and he is Wavewalk’s distributor in Southern Florida.
For the past fifty years, Larry has been involved in using, building, refurbishing and testing motors in various land and water vehicles, including electric racing cars, regular cars and trucks, a wide range of small watercraft, and big diesel engines in stern-drive commercial fishing boats, such as he still operates in Key Largo.

Means and Method –

 

In his tests Larry used five portable outboard gas motors that he had refurbished and tuned himself. Some of the motors had 15″ short shafts, and the others had 20″ long ones, and their horsepower rating ranged from 2 HP to 5 HP. He also tested a couple of electric trolling motors.

Larry conducted his experiments systematically – Being a handyman as well as a mechanic, he built a series of transom motors mounts that enabled him to mount outboard motors of both sizes in various places at the boats’ stern.
In his tests, he changed the height of the mounting plate, and/or its distance from the cockpit’s rear end.

Results –

 

There is no “sweet spot” for mounting a 15″ short (S) shaft motor on a Wavewalk, and any configuration involving the use of such size motor would inevitably result in sub-optimal performance compared to the use of a 20″ long (L) shaft outboard motor of the same power.

The main problems that Larry found with 15″ short (S) shaft outboard were the following:

Ventilation

 

Outboard manufacturers recommend mounting outboard motors with their anti ventilation plate (sometimes called “anti-cavitation” plate) immersed a couple of inches below the boat’s lowest point, which by definition is always immersed. This inevitably means that the anti ventilation plate is several inches below the surface. If the propeller rotates with its blades too close to the surface, it sucks air from the surface, and instead of rotating in water it rotates in a mixture of water and air bubbles. As a result, the propeller loses efficiency and power.

  1. At higher speed – Larry found that with 15″ short (S) motors, ventilation started to occur at about 5 mph, when the boat was transitioning from a displacement mode into a semi-planing mode, and its hulls were slightly raised, thus pulling the propeller upward and too close to the surface. The higher the speed the more extensive the ventilation and power loss. No ventilation occurs with 20″ long (L) shafts, even at speeds higher than 12 knots (13 mph), when the boat is in a full planing mode.
  2. When making sharp turns – Larry found that the 15″ short (S) motors’ propellers sucked air from the surface while he was making sharp turns. This happened since the boats tilted on their side, and the propellers got too close to the surface. In this case, ventilation resulted in loss of power as well as loss of control, to some extent, which made turning more difficult. Such problem did not occur with 20″ long (L) shaft motor, which performed flawlessly in sharp turns at high speed.

Splashing and discomfort

Splashing – In order to avoid ventilation, it is possible to mount 15″ short (S) shaft outboards at a lower level, with its propeller immersed more deeply. This can be done when a specially designed motor mount is placed several inches behind the cockpit’s rear end. However, at such position, the lower part of the motor mount’s vertical mounting plate is too low and too close to the surface of the water, and it will come in contact with the water. In such cases, the result is spray splashing over the motor’s head and into the cockpit’s rear end. No such problems occur with 20″ long (L) shaft outboard motors when mounted correctly on a standard Wavewalk motor mount.

Discomfort – When the 15″ short (S) outboard is mounted several inches behind the cockpit’s rear end, it is harder for the user to reach the motor and its controls (e.g. choke knob, starter grip), and it is harder for them to steer. This is not the case with 20″ long (L) motors that are mounted at the rear of the cockpit.

Bottom line

 

There is no “sweet spot” setup that allows for mounting a 15″ short (S) shaft outboard on a Wavewalk (500 or 700) without it incurring serious drop in performance. The way to motorize a Wavewalk is to follow the recommendations of outboard manufacturers about mounting their motors, as well as Wavewalk’s recommendations that fully coincide with them, namely to use only 20″ long (L) outboard motors with Wavewalk’s kayaks and boats.

 

A sweet spot, sort of…

 

When Larry checked 15″ short shaft, weak electric motors, he found that the ventilation problem at higher speed didn’t occur, because such motors lack the power to propel a kayak at speeds that are high enough to make it reach a semi-planing mode, or have the propeller suck in air from the surface. Knowing about such a sub-optimal performance envelope, the user already expects sub-optimal performance. This said, this rule is not ironclad, and ventilation may still occur in case the boat makes a sharp turn.even when it is propelled by such weak 15″ short electric motors, and while going at low speeds.

This is to say that Wavewalk recommends not to use short shaft motors even in the case of weak electric trolling motors.

In sum, the only propeller shaft size that we recommend for all types of motors is 20″ long (L)

Measuring an outboard motor’s propeller shaft length

Some of our clients who already own an old outboard motor, and others who contemplate buying a used one, ask us how to measure the length of an outboard motor’s propeller shaft, in order to know for sure that the motor indeed complies with the 20″ long (L) standard that Wavewalk requires.
This is an important question, because Wavewalk kayaks and boats work well only with outboard motors that comply with the 20″ long (L) standard set by outboard motor manufacturers, and our company strongly recommends not to use short shaft (S) standard motors.

Here is the full answer:
For this matter, the propeller shaft length is measured from the inner top side of the motor’s mounting bracket to the horizontal anti-ventilation plate that’s above the propeller.

Note that sometimes the anti-ventilation plate is called anti cavitation plate, although this is an incorrect term.

In many cases, this distance between the inner side of the motor’s mounting bracket and its anti ventilation plate can be slightly bigger than 20 inches, and if this is the case, it’s a good thing.

If the distance you measured is under 20″, it inevitably means that the motor does not comply with the 20″ (L) standard.
In fact, most outboard propeller shafts are slightly longer than their stated standard. For example, the length of a 2.3 HP Honda L is 22.5″, and the length of this motor’s short (S) version is 16.5″. Similarly, the length of a short-shaft (S) 4 HP, 5HP and 6 HP Tohatsu is 17.1″.

But don’t fool yourself –  16″, 17″ and 18″ is not 20″, and it’s still a short-shaft (S) outboard, and it won’t serve your purpose.

Why is this so important?

The reason the outboard’s propeller shaft’s length is so important is that it determines both the propeller’s immersion below the surface, which is critical to its proper functioning, and the distance between the propeller’s highest point and the boat’s lowest point, which is critical for trouble-free and effective operation of the boat.

Please avoid using short shaft (S) outboard motors with your Wavewalk 500, Wavewalk 700, and Wavewalk Series 4.

 

Choosing an outboard motor for your Wavewalk® 700 skiff

This article is an attempt to answer some questions that Wavewalk skiff owners ask in the process of choosing an outboard motor for it –

Short shaft or long shaft?

We definitely recommend using outboards that feature a long (20″) propeller shaft, and for multiple reasons, which are discussed in this article entitled Outboard motor propeller shaft length for Wavewalk fishing kayaks and boats »
We recommend not to be tempted by the availability and lower price of 15″ short shaft outboard motors, because such motors don’t fit the W700, and using one would never produce optimal results, even for a highly skilled individual with a lot of experience in boat outfitting.

Here is a list of long (L) 20″ shaft outboard motors currently available in the 2 to 6 horsepower range, and their HP rating:

  • Honda 2.3 HP (air cooled), 5 HP
  • Suzuki 6 HP
  • Evinrude 6 HP
  • Tohatsu 3.5 HP, 4 HP, 5 HP, 6 HP
  • Yamaha 2.5 HP, 4 HP, 6 HP
  • Mercury 3.5 HP, 4 HP, 5 HP, 6 HP
  • Mariner 3.5 HP, 4 HP, 5 HP, 6 HP

Recommended reading –

Air cooled or water cooled?

Water cooled motors are quieter but heavier than comparable air cooled motors.
The only motor featuring on the above list that’s not water cooled is the Honda 2.3 HP. It is very lightweight, and works very well, but being air cooled makes it considerably noisier.

Note: Outboard motor manufacturers recommend flushing the motor’s cooling system with fresh water after every trip in saltwater. It’s possible to flush an outboard with a garden hose outfitted with a special adapter.

4-Cycle or 2-Cycle engine?

Nearly all new small motors on the market are 4-Cycle (4-stroke) and not 2-Cycle (2-stroke).
The advantage of the 4-Cycle system is twofold –

  1. The motor runs on regular fuel, and there is no need to mix it with oil.
  2. A 4-Cycle motor is cleaner, namely it emits far less stinky fumes than 2-cycle motors do.

Some experts argue that for the same displacement of its combustion chamber (cc, volume, size), a 2-Cycle engine in more powerful than 4-Cycle one, but we think that convenience and fresh air are more important.

electric or gas?

Many Wavewalk owners outfit their W500 and W700 with electric motors in the 30 to 50 lbs thrust range, and some go as far as 70 lbs thrust. They use their electric kayaks and skiffs for assisted paddling, recreation, touring, trolling, fishing, snorkeling, etc., but we prefer not to include electric motors in our list of “real” outboard motors for two reasons, which are:

  1. Power – Although some small electric motors are offered as “outboard motors”, just looking at their basic, objective power rating makes us think that they are too weak. Kilowatts to Horsepower conversion: 1 KW = 1.34 HP, and 1 HP = 0.745 KW. Consequently, an electric motor can work well on flat water and at a moderate speed, but not necessarily in adverse conditions, namely strong current, strong wind, etc.
  2. Range of travel – A gallon (3.8 liter) of fuel costs a few dollars, and it’s enough for a typical small outboard motor to run for 4 hours at a high RPM, or an entire day at a lower RPM. You can refuel a small outboard’s built-in fuel tank when you’re on board your Wavewalk®. You can take several gallons of fuel with you on a long camping trip, and you can buy more fuel almost everywhere, while recharging an electric motor’s battery can take half a day. Therefore, gas outboard motors offer a reliable and convenient solution whose price / performance ratio is unbeatable by any electric motor available today.

Weight

All small outboard motors listed above are considered to be Portable. However, between the 29 lbs of the 2.3 HP Honda and the 59 lbs of the 6 HP motors there is a considerable difference, if you need to carry the motor by hand over a distance.

The shallow water position

Most of the small outboard motors listed here offer to lock their propeller shaft in an intermediary position between the vertical (down) and horizontal (up) positions. In this intermediary, slanted position, the propeller drafts less than in the vertical position, and this allows for driving the boat at a moderate speed in very shallow (‘skinny’) water. Therefore, if you’re looking to fish in skinny water, we recommend that you look for this feature.

gear shift lever

Most outboard motors on our list feature a gear shift level, and this is a good thing, because the alternative is a centrifugal clutch that lacks an absolute neutral position. The absence of a full neutral gear can make starting the motor a little tricky, if you’re a beginner.
Our preference goes to the outboard motors that feature the gear shift lever at the front, rather than on their side. The frontal position makes it easier for the driver to access the lever whether the motors points left or right, and even if the driver is facing forward.

built-in fuel tank

All the above listed outboard motors come with a built-in (integrated) fuel tank, and this is a convenient feature considering the alternative is to have a fuel line run from a separate tank to the engine. When you operate such a small craft as a Wavewalk, simplicity becomes increasingly important.

propeller

The propellers that come standard with these outboard motors fit Wavewalk’s kayaks and portable skiffs. Typically, these motors propel much heavier boats, which is why the propeller’s diameter and pitch which determine output in terms of speed and torque are of no real consequence to the owner of a Wavewalk under normal conditions.

price and brand

All the brands listed above are known to produce quality motors, and in fact some of them produce motors for others. For example, Mercury is a Tohatsu brand. This is to say that we see no reason to pay more for a particular name brand, and we recommend to consider only the motor’s technical attributes, and its price.

HP rating – can i overpower my skiff?

6 HP is the absolute maximum for which the W700 is rated, and this is only for its RIB model. Overpowering your Wavewalk can be hazardous, and if you use the wrong motor mount you’d be calling for trouble. This said, if you happen to own a 20″ shaft 5 HP motor and your W700 is rated for a 4.5 HP motor, you can keep your motor, and you won’t necessarily have to get a new one. Similarly, if your W700 is rated for up to 4.5 HP and you found a nice 4 HP that you like, you’d be fine with it.

motor mount

If you choose to make a DIY mount for an electric trolling motor, chances are that you’ll succeed, since these motors are so weak that they’re not likely to cause trouble. But this is not the case with the gas outboard motors in the range that features on the above list.
There are several issues to overcome with motor mounts, and the motor’s weight is the least of them. The main problem is that operating at the end of a 20″ lever, the motor’s propeller generates a great amount of torque, especially at high speed, in rough water and when making sharp turns at high speed. This torque can twist and crack a 4×2 timber, and pull out nails and screws from their place. After having seen motor mounts get broken by outboard motors ranging from 6 to 3.5 HP that were mounted on them, we strongly recommend not to build a DIY motor mount for these motors, and to use only the motor mounts that Wavewalk recommends.

alternator

Some of the more powerful outboard motors listed here can be outfitted with an alternator and an AC to DC converter. Note that such accessories cost hundreds of dollars.
The electric current produced by this system can be used to power lights on board, or to charge a trolling motor’s battery. Such setups are common in bigger boats (e.g. bass boats) that feature much more powerful motors. Although some Wavewalk owners have outfitted their W700 with two motors (a powerful one for driving and a small one for trolling), we don’t know of anyone who’s outfitted their outboard motor with an electric current generation system.

Why an outboard motor?

Skiffs, Jon boats and other small boats sometime come with other motors, among which are air drives or air motors (large diameter propellers) for running marshes and flats, jet drives (similar to personal watercraft, a.k.a. jet-ski), long shaft mud motors for going in shallow water and over obstacles, and outboard motors that run on propane.

While each of these motors offers certain special advantages, and we’d love to see the W700 outfitted with any of them, as well as with other propulsion systems ranging from sails to oars, and even pedal drives… we think the common small outboards such as we listed here offer the optimal mix of price, performance, reliability, versatility, ease of use, and ease of maintenance – Just think how common are boat dealerships and repair shops that service these motors… And if you know how to use your outboard motor and you take care of it, it’s truly a wonderful thing that you’d enjoy for years, and possibly even decades.
