A friend of mine bought the Shockwave 36. Its a real cool looking boat but man his is slow. Well at least slower than I think it should be. It sounds to me like its over proped. The RPMs on the engine sound fairly low when its cruising around, but go way up any time he turns sharply. He has tuned the engine every which way and cant get any more speed. He did the head shim removal and adjusted the prop shaft but nothing helped that much. His boat on plane is still quite low in the water and just looks under powered. I'm sure theres something that can be done to make it better, any ideas? I wanted the same boat but seeing how fast his is I think I would get soemthing different.
