Yeah, so much for the simple solution, seems to sound stronger in the tank than on the boat, but seems to be running on both cylinders.
RPM seems pretty high, but not much thrust coming from prop in the tank. Is the prop in good shape, shear pin and rubber prop hub OK?
Doesn’t idle worth a fart, but that may be due to what looks to be the wrong needle valve jammed into the carb.
Have you done a compression test? Sounds like it has an exhaust leak (leaky exhaust cover?) as well.
Again, seems to wind up, so I don’t think the high speed jet is partially plugged, would probably just bog and die if that were the case. Doesn’t sound rich either, but anything is possible.
Just thought of something. Is this a lightwin or a yachtwin? A yachtwin has a right angle drive propeller, someone may have put a yachtwin gearcase on this engine with the larger pitch 5hp prop which the 3hp could never spin up.
