    Smile Weed Whacker Boat Motor Build

    I figured I'd share a little project I've been working on since last fall.

    I'm building a motor for my marsh rat duck hunting boat and I was finally able to get out an test my weed whacker motor build again. After the last test run in the fall, it was clear that I had to remove the clutch because it was slipping and getting really hot.

    All in all it did pretty well for being a little weed whacker. I had a pretty average top speed of 4.6 mph according to my GPS, but I need to look at all the data for an official number. I was also testing it for the optimum running depth.

    Here's some pics and a short video clip:

    Thumbs up

    Good thread. I posted a thread similar to this on the canoe forum, but I was thinking more of a surface drive.

    I just read your post. The little motor you have would probably work better on your canoe than a weed whacker since you have a regular transom height. I couldn't put that motor on my marsh rat without building a really tall transom.

    Actually, no. The transom mount on the Cruise n' Carry slides up and down the shaft housing to accommodate nearly any height motor mount. I would be interested in making a weed whacker into a long tail, like a mini Go Devil for going in really skinny water. I never thought about the clutch issue, although my little Tanaka has a clutch and it has presented no problem as yet.

    I didn't realize that! Can you tell me how much adjustablity there is? It would be a fun test to put these two motors to a back to back test!

    I say go for it! I'd guess that my clutch problem could be solved by reducing the size and pitch of my prop. It would have been cheaper if I tried that first, oh well.
