so i got my new motor friday (YEA!!!) ive got a few loaner props from friends and the dealer right now im running a 14x17p aluminum and it seems to give the best rpm out of all the props ive run so far HOWEVER at 4900 WOT rpm im still a couple hundred rpms too low, reccomended WOT rpm is 5250 #1 will i gain or loose RPM going from aluminum to stainless ?? #2 how many rpms will i gain going down in diameter 1"? #3 ive ordered a 13x15p four blade rogue do you guys think im gonna be where i need to be with this engine? #4 how can i tell if ive got my jackplate up too high or if i need to go up a hole to lift the motor higher? #5 ive got trim tabs also, how should i run those when running at WOT all the way up ? straight out the back ? down a bit?
