Re: prop size for 21' 1986 sylvan offshore 2.5L

if you scroll down the menu a bit, there is a guy with a 22' 3.0L asked the same question. Don't know how much different it will be for the 2.5L Somebody here is going to ask, what is your RPM @WOT and speed. My 22' 3.0L has a 15 1/4 X 15P. Previous owner told me it was a finer pitch prop so he could get down to slower trolling speeds.
