I have a 73 v4 115 hp serial # 115393m ordered parts "rods" etc, and they say there not to be found, and need to buy a 74 crank. Has anyone heard of this before on the 73 What happened was the mechanic did the no=no on the rod caps and it knocked. I can not get them to sit without some lip on the caps now. So I am buying new rods, etc. or so I thought. The parts people are willing to sell me a used crank for only 100 bucks. Oh the parts people are outboardparts.com. Does anyone know if they are good or not.
