i have a 21ft seville cuddy with a 205 i/o the prop on now is factory 14x19. how big or small can i go with pitch and diameter to change it up for skiers and outright cruising? is 23 pitch too big? any ifo would be great !! thanks jeff
How big or small you can go depends on your WOT RPMs. A good three bladed prop that lets you reach your max WOT RPM is what you want for cruising. Stay with a 19 pitch if you can reach your max RPMs for your engine. If you are reach your max RPM with a 19 pitch, a 23 pitch will turn 800 rpms slower. I would get a good four bladed prop for skiers. Or a wide diameter prop at a lower pitch, like a Mercury Mirage. Try Mercury prop selector. Don't estimate on your speed or RPMs.
