Getting rid of the smell
We had an obnoxious smell (like something died) on our boat once and one of the charter boat captains suggested it was probably the bilge. On his recommendation, we poured in a small amount of biodegradable dishwashing liquid. Then we took the freshwater hose to it, using the nozzle to give it a nice sudsy bath and let the bilge pump take it out. By the time we rinsed enough for all the suds to be gone, the smell was gone too! Can't hurt to give it a try.
