W Kayak Transom Motor Mount For 20″ Long Propeller Shaft

Fishing yayak transom motor mount

W kayak transom motor mount

Model TMM 20 For motors featuring a 20″ long propeller shaft.

Kayak Compatibility: This W Kayak Transom Motor Mount fits W kayaks from the 500 series.

Motor Compatibility: The W Kayak Transom Motor Mount fits electric trolling motors, and outboard gas motors up to 3hp.
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 W 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 W 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 W Kayak Transom Motor Mount is 4.25″ high and 22″ wide, and it weighs 6 lbs.

Attachment: This W 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

How to attach transom motor mount to kayak

  1. Remove the bungee hooks from the cockpit rear
  2. Place the W Kayak Transom Motor Mount on the deck, in the location where you’re going to attach it, preferably as seen in these images
  3. Mark the position of the two holes, and remove the mount
  4. Drill the two holes in the deck with a drill bit whose size is slightly bigger than the bolts’ 5/16 diameter.
  5. Install the bungee hooks back in their place
  6. Insert the bolts in the mount’s holes, put the mount in its place, and push the bolts down, into the hulls
  7. Tighten the nuts with the metal part facing downward, to secure the mount in its place

The kayak’s plastic wall will get slightly squeezed between the mount’s horizontal plate and the nuts.

  4. Another great design brought to you by Wavewalk.

    It is a beautiful motor mount, and best of all, light weight and will not rot from getting wet.

    What is best about the mount, you could leave it on at all times.

    It won’t get in the way of getting in and out of the W500.

    Tight Lines and MoPaddle safe all.

  5. Thanks Rox,
    I’m glad you like it!
    We made 4 prototypes before we came up with this design, and that’s without counting the early designs from Sungjin, Gary T, and yourself :)
    We contracted a local craftsman named Matt Cross who’s doing a superb job turning the Trex boards into something that’s as pleasing to the eye as it is sturdy.
    Each side of this mount is assembled using 6 decking screws (total 12), to assure many years of service.

    Good looking motor mount. I have a 2 H.P. long shaft Honda that I would like to try out. How do I buy one?

    Do I attach eyelets to the motor mount to hold the bungee for the flotation of just leave a bit of room for them?

    at first, using decking material for a motor mount seemed inappropriate to me, but on a second thought this thing is used in outdoor pools and spas, and the way you designed your mount makes it look not too bad.
