My 1985 (#406) 36' presently has a 2 blade 15RH13 prop (Universal 21HP)and I'm thinking about replacing the prop., especially for more reverse control. Any suggestions for a 3 blade prop replacement, ie
itch. I'm being told a 15RH9 to a 15RH12 and can't find a definite answer to the size that should be used.Thanks for your anticipated infoTom
