I have always had the dealer winterize, but this year am thinking about doing it myself <BR> <BR>my only issue is the oil change <BR> <BR>I have the hammerhead, and from what I've read, the oil change is a major PITA <BR> <BR>some posts on the Malibu Crew say that leaving the old oil in all "winter" could be bad for the pan and block <BR> <BR>my thought was to winterize but not change the oil <BR>till I hit the 50 hour mark next season <BR> <BR>the oil was changed about 25 hours ago <BR> <BR>do any of yall think that there is a negative to leaving the old oil in? <BR>.........either through the "winter" (I do the " " cause we don't have a winter like some of yall do) <BR>.....or after start up in the spring?

change the oil <BR>if you leave the old oil in the particulate in the oil will settle in the motor not good <BR>doing the oil change is the easy part <BR>you have a drain line from the bottom of the oil pan clipped to the passenger side block <BR>unclip it run it through the rear drain plug, undo cap nut, and let the oil drain <BR>after running the motor up to temp of course which you have to do anyway to fog the motor <BR>the impeller is the pain in the ass <BR>total time to winterize 30-60 minutes depending on how easy the impeller comes out <BR>have any other question about winterize you're boat drop me a line have the same boat

Change ALL of the oil that is in your boat.
