I have a mercruiser mcm120 in
I have a mercruiser mcm120 in a 21 foot 1983 Galaxy cuddy cabin.I just put it in the water and I tried a 16X15 prop and I am only reaching 3000 R.P.M. and 1/2 the speed I was getting 2 years ago the last time I used the boat I do not remember the prop size and this is not the original prop.Any ideas on what the original prop might have been.This boat is pretty heavy.
