Everything you need to know about properly prepping your boat for the off season.
No one is ever happy at the thought of stowing away the suntan lotion, fishing rods, wakeboards, and water toys for the winter months. But facts are facts: It’s about to get too cold for boating, especially in our part of the country. That means it’s time to prep the boat and all your gear for winter storage.
In Wyoming, our boats spend the offseason in dry storage on land. While there are several elements to preparing a boat for dry storage, the primary job is to eliminate water from the boat’s systems and keep water from getting in during the ensuing months. Water can add excessive weight to your rig, saturate and ruin fabrics and foams, and cause freeze-damage, which is the greatest risk of all.
To prevent any issues, you’ll need to accomplish three basic tasks, in addition to finding a safe place to store the boat:
- Fully drain all systems in the boat that might hold water, including the engine and propulsion system, tanks and plumbing, and the hull itself.

- Remove and stow delicate parts of the boat, such as seat cushions, fabrics, and other soft goods.
Also, it’s important to winterize the engine before storage. Mercury Marine® has several helpful resources for winterization, including the article How to Winterize Your Outboard. The process for a sterndrive or inboard engine is similar, but engines and drive units each have their own requirements, check your owner’s manual to get the full scoop, or you can schedule winterization service with our fully authorized Service Department today.
Once the engine is winterized, heed the following advice to make sure the rest of the boat is ready to go come spring.
Drain the Boat’s Systems
It’s important that the boat is dry when it’s first put away and that it stays that way all winter. Start by draining off every system. Tilt outboards into the full down position so water can drain out. Next, drain all water tanks, including freshwater and sanitation systems. Then pull the boat’s drain plug(s), and make sure the bow is slightly elevated so no water pools up inside.
With the major components now dry, run raw water accessories that have pumps (such as livewells and washdowns) until all the water is out of the system. If you still hear gurgling as the pump runs, that means the system didn’t drain completely on its own. Try blowing the lines out with compressed air or add environmentally safe propylene glycol antifreeze. To add antifreeze, remove the intake hose from the seacock, submerge the end in a bucket full of the antifreeze and run the pump. You might need to elevate the end of the hose and pour antifreeze in to prime the pump.
If the boat has freshwater plumbing, open all the faucets or outlets with the pump running and wait until they go dry. Then close them back up, shut the pump off and add propylene glycol antifreeze to the water tank. Next, open the faucet farthest from the tank, turn the pump back on and let it run until antifreeze comes out of the faucet. Close it, go to the next farthest outlet, and do the same. Repeat the process until antifreeze is running through all the pipes and faucets and your boat’s plumbing systems are fully protected.
One tank you don’t want to drain is the fuel tank, since condensation can form in the empty tank and introduce water into the fuel supply. However, untreated fuel can cause issues when left to sit all winter. Treating the fuel is usually one of the steps of the engine winterization process, but it’s worth repeating here that, after your final fill-up of the season, the fuel tank should be treated with Mercury Quickstor® Fuel Stabilizer. Add the appropriate amount based on the instructions on the bottle, then run the engine(s) long enough for the treated fuel to make its way through the entire system. About 10 to 15 minutes should do the trick.
Prevent Water Intrusion
The best way to stop water from getting into the boat over the winter is to keep the boat covered. A garage is the ideal storage option, but if you don’t have space available, you could have a pro shrink wrap the boat for outdoor storage. Shrink-wrapping fees usually range from $20 to $25 per foot of boat, depending on the prevailing rates in your area, but that’s a worthwhile investment. Shrink wrap completely seals out the elements. You can also use a canvas cover if it’s properly supported and can take the weight of snow and ice.
One final note: Inexpensive poly tarps should be avoided for covering boats. They rarely last for more than a couple of seasons, tend to rip, or sag if they become covered with weighty snow and can wear away a boat’s gel coat or an outboard’s shiny finish if they whip-saw in the wind.
Remove Soft Goods
If you have a safe, dry place like a garage or basement where you can stow the boat’s cushions, canvas and curtains, pull them off and bring them indoors. Keeping them in a humidity-controlled environment will help prevent mold and mildew, extend their useable life, and keep them from developing musty odors. If your boat has clear canvas curtains, remember to roll them up rather than folding them so creases don’t develop over the winter.
Although it certainly isn’t a soft good, another item you might want to remove is the boat’s battery or batteries. Put them on a trickle charger in a well-ventilated garage or basement throughout the winter so they’ll be in prime condition when spring arrives.
After taking all these items off the boat, if you live in an area where rodents could be problematic, consider adding mothballs or heavily scented dryer sheets to a few of the compartments, especially areas where a rodent could get access. The smells they give off will help deter mice and other critters from setting up house inside of your boat.
Boat Storage Options
If you don’t have access to a garage, a driveway large enough to store a boat or a lift where the boat can spend the winter, you can store your boat with Casper Marine and Recreation.
We have monthly, yearly, and winter season rates in both indoor and outdoor options.
