Just replaced water pump on engine used in the salt. Finally pulled the shaft out of power head and pulled PH to look at end cap. The SS shaft is great but the receiving splines in the PH have turned to dust. I have already broken one lower end cap bolt and I'm afraid to continue. Are the receiving splines attached to the end cap or will I also have to replace part of the crank? First time boat repair, any advice is appreciated.<br /><br />Thanks,<br /><br />LS
