I have a Martec prop on my J-30 (hull # 195). When I hauled it out I noticed that one of the cotter pins that hold the shaft that the blades pivot on was missing. This caused the forks of the propellor housing to spread apart. I used a "C" clamp to push it back together. I now have a crack across the forward part of this assembly. Has any one had a similar probleb -if so how did they repair it? Can it be welded. Also how do you get the propellor off? Is it threaded on or what?
