I have a 17.7 alumacraft tropy sport with a 1999 yamaha 115 tlry and a ballist tm 19 pitch prop on it. The problem is I have to over trim the engine to lift the boat out of the water then the prop blows out on corners. The engine is in the second hole mount, also on normal trim the engine sprays 2 water line up the back and 3/4 of the boat remains in the water. Do I need a different prop or should the engine be raised. wot I am running 5300 rpm.
