That could have been a contributing factor, and certainly needs fixed.

Are you sure the drive that came with the 502 is the same ratio?

That could be the problem. You don't have a prop issue. You have an issue with the engine not making the power it should. You should be bumping the rev limiter with the HP increase and the same prop.

I agree with you with diagnosis, I would bet you are on the money.
