well in usual fasion for my brother and i, we decided to build a few mud motors just before duck season. well they both worked for a few minutes lol. anyways it is a surface drive style with a centrifugal clutch and v-belt drive. i am using trailer wheel bearings (tapered bearings) and hub seals. this is not working as well as i had hoped. Ive been searching for good ideas and right now im pretty much just exhausted from hours of googling. should i just run some brass bushings on my prop shaft? also i started this build with a 3 hp briggs engine i had laying around and now im picking up a 13 hp honda to install on it. any ideas would be greatfully appreciated.

now that i have made a motor i am going to be buying a real boat this year, my dads 50 year old paper thin row boat is no longer an acceptable boat.

I will take some better pictures tonight to post them up. but here it is so you can get an idea

any good ideas for this setup?

Whats your question? Im building one. I have it setup from the pully to the prop, the pully, nylon washer, lock collar, sealed ball bearing, needle bearing in the middle, bearing, thrust bushing, brass washer, thrust bushing, single side sealed bearing, cap
