I have an 1820 Robalo CC. When I first got the boat a had a terrible time getting up on plane and controlling porposing. I added a hyrdafoil to the top of the cavitation plate which mada a remarkable difference in performance and fuel consumption. Last year I invested in a pair of Bennet Sport tabs. My opinion.......I should have invested in tabs sooner. I get a much better hole-shot, the ride is smoother, drier, and I spend fewer $$ on gas.

I've got a Mercury 150 Black Max (hydrafoil is off, but the holes in the cavitation plate have been filled). I have a 1994 1820, which is an extremely beefy boat for its class (Robalo has changed the layout and scaled the boat down in recent model years). Part of the problem is the weight of the boat, and I'm certain that an even greater part of the problem is the prop. I have a 17 pitch stainless prop, which really pushes the boat along at top-end, but kills the hole-shot.
