I've just purchased a 2005 225 mercury Optima for my 93 20xd, had a 200 efi on it before.My rpms are too high even loaded with 2 people tourny ready,i borrowed a trophy 26 pitch from a friend, running short straight stretch still hitting 6000 rpm and rising and alarm goes off, I'm guessing rev alarm??, I cant see how much over itll get to get the right pitch, want to find one where I can run wot even with just me and upper rpm with 2 tourny ready, and I didnt gain any speed really since gear ratio is lower than the 200 efi, so do I need to go with 3 blade with more pitch to get my speed back. Anyone have same setup, any help!! alot of money just to guess and not be right
