I could sure use some help. I have a 2006 Crownline with a 4.3L MPI with a 1.62 Alpha 1. With the stock Merc 3-blade(14.25 x 21P) I push 4700-4800 rpm and 53-55mph trimmed out. My problem lies in that this boat has a horrible hole shot(struggles to get on plane). It struggles to pull a deep start slalom skier weighing 175lbs(points the nose to the ski and spins). It is trimmed all the way down. I had a 2002 Glastron SX175 with a 3.0L that could pull a skier better than this thing.
The sympton is that it seems like the boat ca't get enough water around the prop to push it. By easng into the throttle it seems to help. I have tried a Alpha 4 (14x20) although it helped we are still not their...I also push close to 5,000 rpm with that. My brother has a Sea Ray with the 4.3L 1.81 Alpha 1and when using the Alpha 4 (14x20P) he can literally pull the rope out of your hand. Please help as I'm extremely disappointed. Should I be going in the opposite direction(higher pitch)? Please help, at this rate this boat will be sold next Spring.
