A friend of mine just bought a 1980? 16 ft. Skeeter bass boat w/1972? 115 Johnson on it, does not have power tilt and trim ( needs it ). It takes it forever to come out of the hole, it won't get above 3600 rpm's. when trying to come out of the hole until it (finally) starts to plane off, don't know what top speed is, but WOT is 4600. It has a 13 X 19 SS prop, 3 blade, needs work, don't know the mfr. Need to know what prop this boat should have on it................thanks.
