Winterizing a boat and motor is the most important maintenance a boat owner can perform to help ensure safe boating next spring and summer. Regardless of where your boat is stored when not in use (inside or outside), you will need to protect your boat engine.
Boaters who aren’t comfortable doing their own maintenance, should have all the procedures performed by a qualified marine technician. If you have your boat winterized at a marina, boat dealer or boat repair shop, better make that reservation early to ensure getting in before a freeze hits. It only takes a few hours of below freezing temperatures for the water in the engine to freeze and crack the block. Taking a little time in the fall to get your boat and motor ready for winter means that you can be one of the first boaters out on the water next spring. It also helps ensure you won’t have an expensive repair bill!
If you are handy and want to winterize your boat yourself, you will need a good checklist of what needs to be done for the type of motor you have. Inboard, outboard or I/O. You should check your owner’s manual for procedures that are particular to your own brand of boat, engine and trailer. Below is a typical list for each type of boat.
