How Do You Properly Winterize Your Boat And Motor?

Taking the time to winterize your boat is an important method to safeguard your investment during the colder months. It also helps to guarantee that your vessel is ready to go when the season rolls around again.

The process may require some mechanical expertise and time, but having a vessel that runs in the spring is well worth it. Whether your vessel has a gas inboard, outboard, or stern drive engine, here are some ways that you must adopt to ensure you properly winterize your boat. Let’s take a look.

1. Replace Engine Oil

Old oil should be drained before storing the vehicle since the acids and moisture in it can damage the bearings as well as other engine parts. Before doing anything further, get the engine up to operating temperature while submerged in water.

This will allow the unclean oil to drain and the contaminants to be flushed out more easily. Then, follow the manufacturer's guidelines for oil and filters to ensure the best performance from your engine. When preparing a four-stroke outboard engine for storage during the winter, make sure to replace the filter and oil.

2. Drain And Flush The Cooling Water

Water must be drained from the engine to protect it from the expansion caused by freezing temperatures. You can use water muffs or something similar to attach a hose pipe to the cooling system and cleanse the engine using clean water. This works for both sterndrive and inboard engines. Once the engine has reached its usual working temperature, you can stop flushing.

The next step is to take off the drain stops. These parts are often found in the motor's block and manifold. It's also possible that you'll have to take the hose off the pump to empty any standing water.

When performing routine maintenance on an outboard motor, the first step is checking that all drain plugs are open. After that, fire up the motor and run some fresh water through the radiator to clean it out. Utilize water muffs or similar marine supplies online, attach it to a water hose and flush it out for a few minutes.

3. Safeguard Your Engine Parts Using Marine Supplies Online

Engine oil evaporates during storage. This leaves the engine vulnerable to corrosion as well as cylinder scuffing (the rubbing of two metal cylinder walls together) during the winter months.To avoid these complications, a fogging oil spray should be used. This substance is designed to get into the crevices of the motor and coat the moving parts with an anti-corrosion compound.
