correct prop/pitch for 20' w/ 175 opti

[RidgeRunner]

Sting like a bee there ESD.
I think a large diameter big blade 15P like the Mirage would do it for the Seafari with the 2.5liter 175 Opti. Maybe a 17 Stiletto or Tempest. Post them numbers Whitly.
I got an education on props. I could turn a 19p Quicksilver to 5800 RPM on my boat or a 17P Mirage at 5800. BUT a 17p Quicksilver was the fastest WOT overrevving to 6100. Blade design and diameter make a huge difference. Ken at PropGods is one way to go about testing before you buy. Wealth of knowledge there..
