Motorized Fishing Kayak With Powerful Outboard Gas Engine – Korea

Sungjin Kim, from South Korea, takes kayak fishing and touring to a new level. He’s the first to have outfitted a Wavewalk 500 kayak with a full fledged, 2 HP outboard motor:

Stand Up Kayak Fishing Movie From Korea

Sungjin Kim posted this new kayak fishing movie, featuring local kayak anglers:

It’s the rain season in Korea now, and powerful rainstorms are frequent. But although the wind is blowing hard, the anglers in Sungjin Kim’s movie are seen fishing and paddling standing up in their W500 kayaks, undaunted and hardly disturbed at all.

One of the W500 kayaks is outfitted with a powerful outboard gas engine. We hope to get some video of this beast in action!

Airjet Motor on W500 Stand Up Fishing Kayak – Movie

This movie shows a ‘proof of concept’ test we did with the W500 kayak.
The setup includes a 32 cc, 1.2 HP, 4 cycle gas engine we took from a small leaf blower.
4 stroke engines are easy to start, and less noisy than 2 stroke engines.
They produce very little fumes, and therefore are not as stinky as 2 stroke engines are.
You can run for a long time on a 1 quart tank, and carry more fuel on board.

Clearly, the W500 would benefit from a more powerful engine 🙂

This W500 setup presents many advantages, including the lack of both rudder and immersed propeller, which makes it ideal for shallow water, as well as for water where seaweed is abundant.
Naturally, it also makes beaching and launching easy.

You can keep paddling while the motor is running, whether you’re looking for more speed, or for better steering. Needless to say, that you can troll and fish with both hands while the motor is running.
Killing the engine is easy, just by pushing a button on the throttle.
Starting the motor is easy as well, and so is refueling.

Small, Outboard Gas Motors Suitable For Fishing Kayaks

Electric trolling motors work well for trolling on flat water, but when it comes to going in choppy water and in the ocean, another type of propulsion comes to mind, and that is small, lightweight, portable outboard gas engines.
This is because electric trolling motors have a low effective power output relatively to the combined weight of their engine and battery, or batteries. They offer a reduced effective activity time, and that could be a problem in long trips, or in adverse weather.

Another advantage that gas (fuel) motors have is the fact that refueling them is easy, so their range is not as unlimited as the range of electric motors is.

An overpowered boat, or kayak, is unsafe, and keeping safety in mind, most outboard boat motors are too big and powerful for kayaks – even for the stablest kayak, which is the W500.
However, smaller outboard gas motors would work well with the W500.

We do not recommend using big and powerful engines, simply because going too fast in such a small boat (or any boat, or vehicle) can be dangerous, as both directional stability (tracking) and lateral stability are reduced at high speed that can be reached with such motors. Also, the more powerful the engine, the heavier it is, which could lead to steering problems.
