I have a 2000 LaveyCraft Sebring 20'8" with a Merc 3 liter, trim and jack plate. This thing won't pull a tube let alone a skier. I have tried everything from a 21-3 to a 24-4 blade and all I get is cavitation or bogging. I have tried various port sizes on the bravo line as well. Merc says the motor is putting out power but the only way to plane is to put everyone in the front of the boat and go slow.
I could have done this with an electric motor..any thoughts before I hand this motor back to Mercury.
