Wavewalk® Model TMM 20 For motors featuring a 20″ long propeller shaft.
IMPORTANT: We recommend using 20″ (long) shaft motors, since they can be mounted at the rear end of the cockpit, and not a few inches behind it. When the motor is closer to you, it’s easier for you to start it and access its controls, and it makes steering easier. Only 20″ long (L) outboard motors fit outboard manufacturers’ requirements for the depth of the anti-ventilation plate below the boat’s lowest point. Do not use 15″ short (S) outboard motors with this motor mount.
Kayak Compatibility: This Wavewalk® Kayak Transom Motor Mount fits W kayaks from the 500 series.
Motor Compatibility: The Wavewalk® Kayak Transom Motor Mount fits electric trolling motors, and outboard gas motors up to 3 hp.
Important: We recommend outfitting the motor with a long, articulated tiller extension that enables the driver to steer from the middle of the cockpit and not from its rear.
Important: This model of Wavewalk® Kayak Transom Motor Mount can take only a motor featuring a 20″ long shaft. A motor with a shaft shorter than 20″ would be useless for steering if mounted on it, since its propeller would turn in the space between the W kayak hulls, and not below them.
Material: The Wavewalk® Kayak Transom Motor Mount is crafted from 1″ thick Trex board.
Trex is an environmentally friendly, composite material made from recycled and reclaimed plastic, and reclaimed wood. No trees are cut down for the purpose of making Trex. This material is widely used as decking and railing material since it will not splinter, rot or deteriorate due to harsh weather or insects. Trex resists damage from moisture and sunlight, which makes it a better alternative to wood for this matter. Unlike wood, Trex requires no painting, coating or maintenance.
Dimensions: This Wavewalk® Kayak Transom Motor Mount is 4.25″ high and 22″ wide, and it weighs 6 lbs.
Attachment: This Wavewalk® Kayak Transom Motor Mount is easily attached to the W kayak by means of two bolts. We recommend attaching the W Kayak Transom Motor Mount as close as possible to the cockpit, in order to improve stability, access to the motor, control, and safety.

Attaching Instructions For This Motor Mount Model
- Remove the bungee hooks from the cockpit rear
- Place the Wavewalk® Kayak Transom Motor Mount on the deck, in the location where you’re going to attach it, preferably as seen in these images
- Mark the position of the two holes, and remove the mount
- Drill the two holes in the deck with a drill bit whose size is slightly bigger than the bolts’ 5/16 diameter.
- Install the bungee hooks back in their place
- Insert the bolts in the mount’s holes, put the mount in its place, and push the bolts down, into the hulls
- Tighten the nuts with the metal part facing downward, to secure the mount in its place
The kayak’s plastic wall will get squeezed between the mount’s horizontal plate and the nuts.

Safety and Operation
Before going on a motorized trip, verify that the wide wooden bolt knobs that secure the motor mount to the boat are safely tightened to the maximum. Failing to tighten the bolt knobs could result in unwanted vibrations and noise. If you feel such unusual vibrations and/or hear unusual noise, stop the motor, turn around, and tighten the bolt knobs to the max.
Driving with loose bolt knobs is hazardous, similarly to driving with the motor’s clamp screws loose, and it could result in an accident.
Never operate the motor without the motor’s stop switch (“kill-switch”) attached to your arm.
For motor operation and maintenance please refer to the motor’s owner’s manual.
