If you do make an outboard using the weedeater, what type of prop would you use, I only found props that spin about 1.5 times less than the engine rpm, yours would be direct drive (1-1 ratio) and like you said the motor would be probably higher rpm that most outboard motors.
I tried the muffs again today after using the boat (photos below), this time I cranked the hose up to full blast and water did come out the peehole, that was a relief. Having an idea about how many things can go wrong with these outboards I will always try to watch it closely. In fact today at 1/3 throttle, just before reaching plane it started to sound different, it went away after reaching plane and slower speeds. Hopefully the sound change was becuase of some type of transition between not on plane and getting on plane what do you think? Had a total blast today on the water, it brought back so many memories when my dad used to take me out on his yacht (33' silverton twin gas 300 hp engines) or his 16 footer/50 hp(we called it "the green boat"). We did not really take this boat on the open ocean, its a bit too small for that. Most boats should be at least 16' I think unless its a boston whaler then maybe a bit smaller. We launched at long beach harbor beacuse there two miles from the coast there is a break water jetty that runs parallel to the coast and is 8 miles long. It keeps the water calm for the cargo ships that come in. The only thing that seemed to go wrong was when I pulled the trailer out of the water, the right trailer light turn signal did not respond, althogh it did respond to the brake light. But I dont mind we had so much fun today. Photos below..
