1975 SF 18 going under the knife.

Only thing I can think of is more moisture around the tank.

So Boo, you are saying the coffin just gives moisture the opportunity to linger around the tank?

[uncleboo]

Thinking if you mount the tank in the bilge, it will be exposed to more moisture. My coffin has a 1" drain hole in the rear and the hole where the rigging goes through allows it to have some airflow, not much, but, some. I installed inspection plates over the fill hose fitting, sending unit and pick up fittings so I can inspect or vent if it gets moist.
