I have a 2002 Sun Tracker 21 ft. Pontoon w/ MERCURY 40hp.
2-stroke. Two cylinder. I have a MERCURY Black Max prop
that is 12 1/2" X 9" (3 blade).....the top of the blades are the
same height as the bottom of the two toons.
I only get 4900 rpm's and 13 mph....and when it hits 4900 rpm
the prop blows out.
ANY SUGGESTIONS on the next prop???
(I'd like 5500 rpm with 15> mph.)
