I'm running a 1998 champion 203 with a 225 optimax and I bought the boat with a trophy 4 blade 25p prop that's stamped "champion" on it. Guy says it's the original prop he got with the boat new. Boat won't power load at all. When I try to pull up onto bunks a little it stutters. Merc 3.0 forum says I need a different prop. Going from the 4 blade 25p what pitch should I get in a tempest? Right now I'm getting 5700rpms at 68 to 69 mph on a perfect day. I don't really want to turn anymore rpms since the opti is a 98. Would like it to last as long as possible. Should I get a 25p tempest or 26 to test out?? Any tips would be greatly appreciated as I don't really want to have to buy multiple props just to get something that will work decent
