Have you considered lower pitch prop? It will hold speed better and be easier to fine tune speed. You will lose top-end speed and with 90hp, you may not have much to sacrifice. How important is top-end speed and is wakeboarding the primary use of the boat? PP is is a good solution and probably the most expensive. I would look to more economical solutions to the problem. Or, take the $$ for PP along with the Bayliner and trade in for a boat thats up to the task. One more suggestion - ride as a passenger when not on the board and coach your back-up driver instead of taking the wheel everytime your in the boat. It's tough because you want to give everyone a perfect ride, but then your ride sucks. After all it is your d*mn boat and your entitled to a decent ride. I completely surrender the helm to my wife when the boards come out and enjoy the ride. She doesn't ride so everyone gets the same pull - maybe not as good a driver as me, but when it's my turn on the board, I end up with a much better run. I enjoy nice long runs on the water 'cause after all it's my d*mn boat.
