the prop on there is a 15- 1/2 X 15 aluminum. She really jumps onto plane, since I had it repitched I can get 5000 on Tach ( if Tach is correct ) but doesn't feel that powerfull only 30 mph. on GPS. Last year I got 30 mph at 4000 RPM. I will do a compression test on all cylinders, if that is good I will research if doing a seafoam treatment that everyone talks about on this forum will be safe to do to my engine. maybe that is all it needs.
