I have a 2008 190 SSI with a 4.3 220hp Volvo Penta, with a 4 blade 19" 14.25" prop. I want to increase the low end performance to get on plane easier and quicker. Would changing the prop to a 17" (or even lower) SIGNIFICANTLY improve the low end performance. I'm OK loosing some top end performance. With 4 or 5 adults on the boat, it is hard to get on plane (even with 2 of them in the bow). Would this create any issues or overload the engine? Would a stainless prop make much difference. Any suggestions or experiences from others who have the same boat?
