Staying Dry in a Motorized W500 Kayak

Bob Glandon (duck hunter) travels a good distance in the water to reach his hunting spots. To speed things up he mounted a 15″ outboard motor to his W500.

Since such short-shaft (S) motors are not standard for use with Wavewalk kayaks, at high speed he was still getting some water splashing up and into the boat from the open space between the shaft of the motor and the cockpit.

Engineering is Bob’s background and here is how he solved the problem:

Short-Shaft Motor on W500

Bought two 11x32x1-1/4″ open cell kick-boards at the grocery store (only used one).  A little stiffer than a pool noodle stock.

I stuck one end up above the underside noodle floats and bungied the back to the motor mount with it sticking back to make contact with the motor shaft.

Ran it around in the chop of Lake George, NY, off my dock and didn’t get any water in except some side splashing.
I rode forward slightly but kept the bow up for the wake chop so I’m sure I would have gotten water without the deflector.


Didn’t shape the Decorative fins but could to shape to motor. Foam meets the motor above the swivel point so I can get a tight fit.

Secured splash-blocker… no drilling!

Back shock cord goes up to motor mount. One 6″ forward goes up onto inch clips on deck.  The unused board gives perspective. A 13″ wide would have been a snug fit but the side flanges of the motor mount seal it fairly well.

This provides an additional 16# floatation should you swamp — or slide way back while catching a big fish!
Simple and cheap!

Thanks Bob, a really smart solution!

Note that Wavewalk recommends motorizing with 20-inch shaft motors, so that the head can be tight to the cockpit, the unwanted splash eliminated, and overall performance optimized.
