AaronM Posted July 30, 2008 Share Posted July 30, 2008 I have an Evinrude Intruder 115 with a stainless 13*20 prop. I'm looking into aluminum props; I just replaced a lower unit and want to avoid that in the future. My hole shot is OK, and top speed I'm getting around 5,500 RPMs. What kind of pitch should I be looking at for aluminum? Same setup or should something be tweaked? Also, does my stainless have any trade-in value if I'd want to go that route? Thanks for any help! Link to comment Share on other sites More sharing options...
marine_man Posted July 30, 2008 Share Posted July 30, 2008 You probably could go to a 13 X 21 and keep the same performance, but your hole shot will suffer a little bit.You should be able to get some value for your stainless on trade in - that or sell it - stainless are always worth more than aluminum.marine_man Link to comment Share on other sites More sharing options...
ricqik Posted July 31, 2008 Share Posted July 31, 2008 Always go a pitch higher on aluminum to compesate for flex. Plus Evin will be happier, less sprung weight to turn. Link to comment Share on other sites More sharing options...
