Looking to replace a damaged prop on my 1984 mastercraft Stars and Stripes. It has 351w ford 1.52:1 power slot 1-1/8" shaft LH rotation. Current prop was 14x18 3 balde oj. Use of boat is slalom, wakeboard, knee board and tubing. At times will fill 1500lbs of ballast. Thinking 4 blade but not shure. Also looking at strut bushing and a dripless seal.
