The Importance of Winterizing Your Boat

As the boating season ends and the cold winter settles in, it’s important to protect the investment you’ve made in your boat by making sure that you winterize it properly. Failing to properly prepare your boat for the winter season can lead to problems while your boat is in storage, leading to a good chance that you need to make repairs to your boat in the spring.

Winterizing your boat may be more simple than you think. As Discover Boating discusses, winterizing your boat for the cold season is a worthwhile investment of time and money that helps you rest easy, knowing that you won’t run into any problems when it’s time to put it back into the water.

Winterizing Your BoatEngine

One of the first things you want to do when winterizing your boat is focus on the engine. For inboard engines, Discover Boating recommends allowing the engine to for a few minutes to warm up and then changing the oil and the oil filter. You should also flush the engine with antifreeze, using an intake hose connected to the water pump and running the engine briefly so that it circulates through. This is also a good time to check transmission fluids and spark plugs, as well.

For outboard engines, you should add fuel stabilizer to keep your gas usable through the freezing season. You should also run the engine for a few minutes with the cowl off and spray a fogging solution into the air intakes. As you do this, remove the fuel line and allow the engine to run off residual fuel until it stalls out, burning off any lingering traces of fuel in the carburetors and helping minimize any deposits from evaporated fuel. Last, grease the propeller shaft and threads with a water-resistant grease and change the lower unit’s gear oil. Finish with a wash and polish or wax.


As with the outboard motor, if your vessel has any gas tanks, be sure to treat remaining fuel balances with stabilizer. Some ethanol fuels can spoil easily in cold weather, while partially full tanks can leave more opportunity for condensation to form, adding water to the fuel. Whether you opt to store with a full tank or not, stabilizer is intended to minimize the impact of winter conditions and help preserve your tank for the spring boating season.

Onboard Systems

Before you leave your boat in storage, you also should go through and remove any valuables and electronics. Electrical items tend to suffer in cold weather, even when disabled, so taking them home to a climate-controlled space can prevent problems the next season. You should also pack up your flares, fire extinguishers and flotation devices. When you get the boating itch over the snowy months, you can look these over, making sure that they are still in good condition and clean or replace as necessary.
