Winterizing your favorite fish-catching machine is probably one of the least favorite chores of fall, but knowing how to winterize a boat is an absolute necessity in order to maintain the longevity of your boating lifestyle. The individual steps may vary slightly based on the average low temperatures for your area and the type of motors or accessories your vessel may have. However, the major goals of draining the water from the engine and lubricating as many of the internal engine surfaces as possible in order to prevent corrosion or internal damage will be the same.

By taking the time to thoroughly complete your boat winterizing duties, you'll prevent more expensive problems later down the line. At the same time you'll be addressing any issues that are best handled by an expert mechanic during the off-season when they are less busy. This will mean more time on the water and less time that the boat is in the shop or with the mechanic come spring. As with any type of boat maintenance, be sure to check your owner's manual for specific manufacturer instructions on winterization since boats and engines can differ.

Before you get started with the winterizing process, it will help to make a checklist of the items you'll need. This list will include:

boat stands

plywood bases

pressure washer


earmuffs or flushing kit

boat trailer

fresh water source

non-toxic antifreeze

fogging oil



lithium grease


oil filter

fuel stabilizer

grease gun

gelcoat paste

boat cover or tarp

tie-down straps

The more time you take storing and winterizing your vessel properly, the less money you'll have to spend on repairs, the more time you'll have on the water, and the more hassle-free use you'll get to experience next season.
