How to Winterize a Sea-Doo

How to Winterize a Sea-Doo

One of the worst days of summer is the final day where you have to take your Sea-Doo out of the lake! While the last PWC Joyride of the year might feel a bit bittersweet, you need to remember to winterize your Sea Doo after. This helps ensure your favorite toy works as intended the following boating season.

The six steps below will teach all PWC owners how to winterize a Sea-Doo properly and efficiently. Learning how to winterize Sea-Doo is key to keeping your PWC in tip-top condition for years to come. Keep in mind that while our advice will help prep your Sea-Doo or PWC for next year, we always recommend consulting your owner’s manual for your manufacturer’s specific instructions on Sea-Doo winterization.

1. Drain The Water

Right after you take your PWC out of the water for the season, we advise you drain the excess water from its cooling system. A Sea-Doo naturally utilizes the cool water from the lake or ocean to lower the temperature of its internals.

To drain all the water, we recommend running the engine in 30-second intervals while tilting your Sea-Doo’s handle back. After all the water is out of the system, we suggest flushing the cooling system to ensure all dirt, algae and grime is removed from the vessel. Again, you should follow the instructions in your owner’s manual to ensure you flush your system thoroughly as part of your regular Sea-Doo winterizing process.

2. Clean Your Toy

It’s extremely important that you clean your Sea-Doo before you dock it for the season. Wash the hull of the PWC with a mild soap. After you scrub the hull, clean and wax the shell of your vehicle to protect it from UV damage and wear. Next, clean the bilge area of your PWC to wash away any excess grime.

3. Fill & Lubricate Your PWC

Another important step in winterizing a Sea-Doo is to fill the gas tank up to the top with a stabilizer to keep it clean. Make sure to read the directions on the stabilizer bottle before adding it into your fuel tank. You should run the engine in 30-second intervals to ensure the stabilizer is well mixed in the fuel. After stabilizing your fuel, you should lubricate all seals and cabling using a lubricant and protectant recommended by the PWC manufacturer.

4. Oil Your Sea-Doo

Your next step in this Sea-Doo winterization process is to spray the carburetor and spark plug cylinders with a fogging oil. You will need to remove the air filter from your Sea-Doo in order to access these parts. Once the filter is removed, turn on the engine and spray the spark plug cylinders and carburetor while the engine is idling. You should continue to spray until the engine stalls and replace your air filter once you’re done.

When this is complete, make sure your spark plug wires are grounded and then remove the spark plugs. Spray fogging oil into each hole for a couple of seconds. We suggest placing a rag over the holes and turning the PWC on. This will allow the oil to coat the internals of the vessel. It is normal if your engine does not start. Once this is done, clean the mess you might have made and reinstall the spark plugs.

5. Remove The Battery

Leaving your Sea-Doo battery in over the winter can reduce its charge. As part of your regular Sea-Doo winterizing process, you should take the battery out of your PWC by removing the negative connection first, followed by the positive connection.

6. Safely Store Your PWC

We suggest storing your Sea-Doo on a trailer with the trailer wheels off for easy maintenance. You should also place some kind of noninvasive material in the exhaust to prevent animals or bugs from crawling in the engine. Believe us, this does happen! Next, cover and store your vessel in a safe spot.
