hey guys, i purchased a boat last year, and it runs great it's a 2004 four winns h170 with a volvo penta 3.0 engine 135 hp and a SX drive, it has the original prop on it that is in pretty decent shape, it is a 14.25 X 21P alluminum prop. It seems to do pretty well even though i put a few dings in it last year due to low water levels. So my plan is to get it refurbished this year and use it as a spare because i dont have one right now, and i wanna get a new one, reason being is that the max WOT RPM recommended is 4600rpm and i can easily get 5000rpm out of it (havent tried to get anymore, i stop trimming up at 5000) so i would like to go to possibly a 23P prop and get a few more mph's out of it and drop the rpm's a little bit since i'm going over the max wot rpm. So i've been researching props lately and i'd like to get a stainless steel 23P prop but i'm not sure which one i should get, the diameter of my current one is 14.25, but i see there is other diameters, what's the difference in diameters? i know the difference is that much, but they are different. Also my next question is, what's the better brand? or does it make a difference, i see some under $200, and some up to almost $500. Sorry for the long post but there are so many choices and i have never bought a prop before, so if you could at least get me started, i would appreciate it.
