smart tabs on a heavy boat

That's been my experience - outboard too low. With the engine in neutral trim, you should barely need any tabs, or none, to avoid porpoising in flat water.

With an IO, engine height is not an option - obviously. They're left with motor trim, trim tabs, prop selection, etc as the alternatives.

the trim tabs work great but now i'm thinking about the prop,it says 5052-17 on the side,i cant even find it on the web it's a s/s prop the rpm and speed is close the motor does'nt overrev but with a 350 i think it should have some more get up and go
