Maiden voyage observation

They help the boat plane at slower speeds, cheap trim tabs and not as efficent, they do work though. They will provide spray, particuliarly if the engine is mounted to low, keep the cavitation plate about 1" to 1 1/2" above the keel. They also cut some top end.

Whether you want to drill new holes or not you may have to - that is some crappy rigging. Not sure on the motor tilt but I would bet its way too low hence the dol-fin. That lower hole will not allow to raise it I guess, but I will bet to get to 1-1 1/2" above you will have too. Not that bad just do it right and its not that hard, these guys can tell you exactly how to plug the old ones. keep that 115 under 5400 RPM though - just say'in

Yeah hard to imagine the boat yard that sold this boat in FLA. thought that those bolt patterns were correct. I don't officially know what is correct but I'd prob. lean toward mounting bolts in the middle of the bolt pattern which would allow for motor up down adjustment without new holes.

That said I have a 1 hole adjustment left. I'm not sure where that puts the cavitation plate on the transom, I'll play with that tonight. Never the less, I'm going to rip those dol fins off as I think they look silly and I think the payoff to be minimal.

New prop on the way, the mangled one was a 13.25x17. I'm trying out a 13.25x19.

Tx for your previous reply!

That will probably be too much, you will need a 17 especially for water sports
