i think your on the money here.
those b 3's grab a lot of water; thats the idea. both of them going bad at the same time isn't likely
also the b 3 doesn't use bushings. there are 2 nuts per drive to hold the props on and thats it. they spline up, metal to metal, on the out put shafts
i to think your looking for drag or performance issues
Performance would likely not be both engines and drives, they perform the same. When getting on plane, if I move one throttle slightly more than the other it will blow out that outdrive. I am only talking a slight throttle position differance, like a little accidental twist of my hand. I've done all the mechanical tests and been in contact with Signature Propellers and Mercruiser and they figuerd the same slippage and recommend 20P props and say it is not uncommon to have the wrong prop from manufacturer. I was just wondering if I am the only one with 22P's on a 310 that has changed them. Thanks for the input guys.
