I just bought a 1991 Four Winns with a 4.3L OMC with Cobra outdrive. I am going to store it in the corner of a dry, heated factory building. The temperature will never go below about 65 degrees. Doing a complete winterization seem a bit much. What do I really need to worry about over the 6-7 months it will be stored?<br />I just sold my Glastron with Volvo-Penta which I always winterized and stored outside for 10 cold Michigan winters.<br /><br />Advice and opinions would be appreciated.
