One solution is to close the sea cock, I prefer to install a hose and valve to the drain on the muffler.
Its required to winterize , should that ever be required.
Accidentally leaving the muffler drain open is no big deal , you will hear it and the bilge pump will easily keep up.
Far easier to close a valve than do 2 oil changes.
I like the drain idea but don't want to have to go down there to try to install a drain. The muffler is in a bad place and I'm tired of contorting myself.
After removing and reinstalling the injectors I did close the engine seacock thinking I might have to crank for awhile, bleed lines, etc., but to my surprise it started right up. I figured those injector lines would have some air in them but I guess not. I think I read somewhere that this JH Yanmar was "self bleeding", however that works.
