I replaced all four tanks, with epoxy painted steel. I increased the aft tank sizes by 120 GL each. Total tankage is now 1240 US GL. Removing the tanks meant removing the engines. So I re-powered. Basically the ER was taken back to bare hull, painted, and mostly new stuff put back. A major re-fit.

Pics of rust below. First one show aft corner of tank where the leak was situated. Second pic after tank removal. The tank was resting against the hull side, trapping water. Water entry was from ER vents with vertical louvres that had no dorade protection. Water entry would mostly have been rain. It took over 30 years, but it ended up a big problem. There was a lot of flaking rust along the bottom edge of the tank.
Do you have any pictures to share of this major upgrade??
