I would like to get a little more top end out of motor for 14' Stumpknocker. Motor is short shaft with SE 200 foil...cav plate currently sits about 1" below transom but I do plan on raising it 2-3" with riser/JP. I tested it with the following results...OEM RPM range is recommended 5200-5800. Current prop is OEM 3 blade, 9.2x9. Light load....3 gallon tank, me, motor, and about 30 # of junk in side storage. Best trim setting was # 3 hole in bracket....average 21.8 mph at 5550 rpm. At next trim setting, # 4 hole, top end increased about 1 MPH but so did extended bow rise during take off. I'm open to considering a better prop like Powertech...perhaps a 4 blade in pitch of 8 with heaving cupping???
