*grin* I've tried being such a contortionist, and have the fiberglass-abraded arms to prove it!
Every winter I stick a flexible hose through the engine mount cutouts and use my oil pump to drain it as best as I can.
OK, another question while we are on the subject....
There are two limber holes on the outboard ends of the track that holds the companionway steps. What happens to water that reaches those holes? Does it go to that undrainable void below the Yanmar? (Which would make no sense; why add limber holes if they can't drain anywhere useful?) Or did they do something special to get around the vermiculite problem?
