This stems from a post I put up a couple of weeks ago. In a nutshell, I've been draining my block and exhaust manifold after each use. Boat probably sits on the trailer inside dry storage at least two weeks before I put her back in the water. My thinking was keeping the cast iron parts dry, will prolong exposure. However, others here have said just the opposite, especially since I'm running a fresh water cooling system. That got me to thinking when it comes to winterizing, what do ya'll do? Do you totally drain the block and manifolds, or do you get antifreeze in the block and manifold and then store it. I typically will drain the block/manifold and pour some antifreeze down into the water pump and call it good. That methodology has worked for me since '99. I'm just wondering if I'm actually doing harm as opposed to doing good to those problematic rust areas.
