Let me hear your opinions on which prop would be best for my boat to get top speed. There are so many SS props out there it's hard to pick one. I have a 17'9" Manta Ray bowrider but I'd put the actual length at around 16.5 cuz it has the molded in swim platform over the outdrive. The boat weighs around 2000# with a 135 Mercruiser 3.0 I/O. My best speed on the GPS is 42 with the Hustler 19P aluminum prop. I know that with the 3.0 it's never going to be a speed boat..alas..sigh.
