HarryG, I am assuming you just removed or plugged the hoses going to the vents on the side? The vented caps are probably better all the way around --especially with the seas we can encounter in the Bay. I hadn't really thought about sea water going in, but I do not see why it wouldn't.

Brian, I am very familiar with Deltaville. I spend a lot of time there sailing with friends. Also spend a lot of money there at West Marine and BoatUS!
