Re: Need to winterize mercruiser 4.3 I/O, manuals are waterlogged
Since you say you are a newbie, do a search on this forum for winterize. There have been a lot of postings with recomendations for what to do to winterize your boat. <br /><br />A good winterize procedure includes a lot of things, many of which are not specific to any particular engine. (change oil, fog engine, store cushions where they will not grow mildew, pull battery to keep charged, etc.)<br /><br /><br />Regarding questions specific to your engine can you give us details. What model boat, model engine, model drive, etc. For example, I have a 1988 Chapparrel model 198XL with a 5.0L GM engine and an OMC sterndrive.
