    Default Has anyone homebuilt a surface drive yet?

    Everytime I go to Home Depot the lawn mowers seem to suck me in. Some angle iron, some welding time, get a SD prop off the internet shipped up... it can't be that hard.

    I do see that a snowblower motor with the crankshaft coming out the side would be easier to work with than a lawn mower with the crank coming out the bottom.

    But still, it can't be that hard.

    Can't be that hard to build one if it is a long tail. I bought a China made horzontal shaft 6.5hp for $100 at Harbor Freight. Just haven't gotten round to working on it since I'm busy moving.

    I also came up with the jet drive unit from a PWC that has possibilities as a surface drive too....maybe next winter.

    Just do it so we can learn from your experiences!!!

    I built a 3hp long tail for my canoe. There wasn't a whole lot to that. I'm considering building a 20hp SD but haven't got to it just yet. My main hold up right now is a prop. They are about $200 and that's over my budget right now.

    Yup, $200 seems to be about the going rate for an SD prop. My main concern is coming with high enough grade angle iron that I wouldn't have to build it twice.

    I posted pics on page 5 of this forum on 10/14/2011 in a post about SD vs OB Attachments 54123,54124,54125 but they don't seem to work for me. Maybe I can post some more tomorrow if swmbo cuts me some slack.
