=D> 1980 Monarch 14ft x 48in short transom 15in
8) 1980 15HP Johnson with 9 1/2 x 10 prop (what it came with from manufacture) short shaft 15in
Mini Jacker provides 3in lift
:x So that puts my anti-cavitation plate 1/2in above keel.
So what went wrong. Today think I had a blowout (spun hub on three week old prop. Had to baby it back to boat ramp as it would not go over 5mph. Got home to check my lower end oil that's good. Looked at prop but can't tell it's slipping just by looking at it.
Me, wife, some fishing gear full tank of gas 5,000 rpm @ 16mph. This motor should be in the 5,500-6,500 range.
