Inboard Propeller Selection

[omaier]

I have a '76 SC23 Inboard that was repowered with a 230 HP Yanmar diesel. I currently run a 16x17 3 blade w/ light cup (Michigan Dynajet). The boat cruises at 28-30 kt and tops out at 33 kt.

My primary concern is initial acceleration out of the hole. When I have a load of people or full fuel tanks, it is difficult/impossible to get the boat over the hump. But, once over the hump and on plane, the boat accelerates and responds very well.

I was considering a 17x17 4 blade to help with initial acceleration.

What do you fellow inboard owners run? Any thoughts on what size propeller to use with my setup? How do the other inboards perform during initial acceleration?

Thanks in advance for your help!!
