Re: Homemade outboard motor using briggs 2hp

68.4.213.15

Tried ebay for the gearbox, no dice. The centrifugal clutch is not a bad idea..where can I get one where I can just drive and pick one up other than have to order it? The ones I remember when I was a kid were really noisy though, like a sledgehammer hitting steel 3 times a second.
I am concerned about the idler pulley causing the belt to come off too, but even with a clutch I must have a way to take up slack in the belt. If I weld this thig together to exactly fit the belt, it may stretch later or I make be 1 inch off etc. I thought it safer to be able to loosen tighten the belt at will. I pretty much got done with the drawing except for the idler pulley assembly if I do that. I found a smaller drive and driven pulley to use (1 3/4" drive and 3" driven) so the lower PVC T in the drawing will hopefully be much smaller than shown. I estimate that this thing is going to weigh in at least 50 lbs with motor (the motor is about 30 lbs I think). I might just start builing this thing and wait and see what it looks like before dealing with the idler/clutch issue.
