Just purchased a 2006 Hewescraft 22' Ocean Pro with ET. The 2009 Suzuki 140 hp motor has 60 hours on it. The motor has a tendency to readily "cavitate" while trimming and I feel that the motor needs to be mounted one notch lower on the transome which I will do this spring. It runs great and the good thing is that it still has a 5 year transferrable warranty left on it.
Now the question: The boat presently has a 4 bladed 17 pitch prop on it. With three people on board and half tanks the boat does 23 mph at 4800 rpm on slick water. 33 at 6200 RPM. Seems like a lot of RPM for the speeds indicated. I'm going to go to the THREE bladed 17 pitch prop first and then try a 19 pitch three bladed prop. The 17 pitch will allow the motor to turn 6200 which the top number for the motor for maximum horsepower.
Does anyone out there had any information regarding my motor/prop/boat configuration?
