Making the set screw holes might work fine, these are like industrial grade bearings, the spec. sheets on them actually gets into the 1000's of pounds capacity. The reason I got them was because they were the only ones I could find. So I am thinking I will try the holes first rather than deal with a thrust bearing adding to this design. As for the math, I dunno I am just thinking back to high school physics I think. They numbers could be way off and it was kind of odd that it did not account for boat mass. The truth is, I do not have a boat lol. I plan on putting this in a garbage can full of water to test it and if I am lucky maybe I can rent a skiff to try the motor out on or maybe somebody else will test it out for me on thier boat. I figure the boat plus people (up to four) and everthing might be like 700-1000 lbs, pretty heavy for that little motor but then again it doesnt have to push it that fast. (the reason i came up with 5 mph is because that is the harbor speed limit, I want to be able to keep up with traffic so we dont get run over by some huge yacht). Piping the exhaust to the water is a great idea, the motor is going to be louder than your normal outboard. I wonder if piping it to the water would make it quiter. Are exhaust threads on these things pretty standard? I wonder if a threaded copper or plumbing pipe would screw right in where the muffler goes.
