My locker developed a leak in the hose connection of the locker to the transom. A 1.5 in x 10 in Hose. Very difficult to find. When the boat is heeling to Stbd, the transom fitting is below the waterline and backfilling water into the boat. This area is very difficult to work in but some Rescue tape and tightening the clamp got me by. I plan to replace that hose in Spring.
I have no LP gas appliances on my 1984, Hull 484. I use the locker for beer and ice since it has a drain.
