I'm about to winterize my 2000 18 Classic. I have always drained the block and filled with anti freeze. These block drains are an absolute PITA to get to. Can I get away with just using the gravity feed plastic containers that feed the anti freeze into the block while it's running? I always do that anyway and then back fill from the thermostat area after I shut it down. The boat will sit outside covered in New England. Just trying to make things easier.
Thanks for any input.
