i just bought a 2006 Sundeck 200 with a 4.3 MPI engine. I put a new prop (14.25 and 17 degrees) on it. It has very little power out of the hole and takes a while to plane. It tops out at 4,100 RPMs and only 28 mph. The engine only has 153 hours on it. It is disappointing. Is there anything I can do?
