Re: Keel Bolt Questions from new owner
Is your fuel tank aluminum? My 1992 PSC 34 is and if bilge water can complete the circuit with your SS keel bolts you may get pitting in the tank. I pulled my tank and had to have plates welded onto my tank. I then epoxied over the bolts in a way similar to what you show in your photos. I think that's an excellent way to prevent a bimetal reaction.
