As the temperatures start to cool and the days grow shorter, the boating season is drawing to a close. While those sunny afternoons on the water may be behind us for now, it’s important to make sure your boat is ready for the months ahead.
Properly preparing your boat for winter can prevent costly damage and ensure that it’s ready to hit the water again when spring arrives!
To help you navigate the winterizing process, we’ve compiled 10 must-know tips that every boater should follow. Whether you’re a seasoned captain or a first-time boat owner, these steps will help protect your investment and keep your boat in tip-top shape during the off-season.
#1. Thoroughly Dry Your Boat Before Wrapping
Moisture is your enemy when it comes to winter storage. Make sure your boat is completely dry before wrapping it for the season. Any remaining water can lead to mold and mildew, which can cause extensive damage to the interior. Use a dehumidifier, towels, and fans to eliminate as much moisture as possible. Remember, a little extra effort now can save you from dealing with costly repairs in the spring.
#2. Prevent Animals from Nesting in Your Boat
Animals love finding cozy spots to shelter during the winter, and your boat could be a prime target. To keep them out, eliminate as much access as possible by sealing gaps and securing covers. Consider installing a Shrink Wrap Door so you can easily check inside periodically throughout the winter for any signs of intrusion. Rodents, in particular, can cause significant damage by chewing through wiring and upholstery, so it’s worth the extra diligence.
In addition to sealing your boat, use natural deterrents to keep pests at bay. Place mothballs throughout the interior and under the trailer to discourage rodents. Rodent-repellent oils containing mint and other essential oils are also effective, as many critters dislike these scents. Bowls of Pine-Sol can also help repel animals; place them strategically in and under the boat.
#3. Change Gear Oil, Engine Oil, and Filters
Changing your gear oil, engine oil, and filters is crucial before winter storage. Gear oil should be replaced annually to prevent corrosion and maintain performance. Also, replace your vent and drain plug gaskets.
Engine oil changes are not required every year, however, this really depends on how often you use your boat. If you frequently boat, an oil change before storage would be a good idea. Don’t forget to inspect and possibly replace the fuel filter and spark plugs, depending on their condition.
#4. Flush the Coolant System and Add Antifreeze
If you have an inboard/outboard (I/O) engine, flushing the coolant system is essential to prevent freezing damage. Use a RV antifreeze rated for at least -50 degrees Fahrenheit (or -100 degrees for extra protection). Waiting too long to do this could result in serious engine damage, so make it a priority before freezing temperatures hit.
#5. Care for your battery
Proper battery care is key to extending its life. You have two options: either disconnect the battery, turn off the switch, and leave it in the boat (but remember, you’ll need to charge it at the start of the next season), or remove it from the boat entirely and connect it to a trickle charger/maintainer. The latter is the best option for battery longevity, and it’s ideal to store it indoors if possible.
#6. Use Desiccant Bags and Vents When Wrapping
When wrapping your boat, use desiccant bags and vents to control moisture and promote airflow. Desiccant bags help absorb moisture trapped inside the wrap, while vents allow air to circulate, reducing the risk of condensation, mold, and mildew. These small steps can make a big difference in maintaining your boat's interior condition.
#7. Opt for High-Quality Wrapping Material
Not all boat wrapping materials are created equal. Use a quality shrink wrap that is at least 7 mil thick (thicker is better) to provide adequate protection against snow, ice, and UV rays. Thinner plastic may be cheaper, but it’s less effective at safeguarding your boat from harsh winter elements.
#8. Add a Fuel Stabilizer and Run the Engine
Add a fuel stabilizer to your gas tank to prevent the fuel from degrading and gumming up the fuel system over the winter. After adding the stabilizer, run the engine for a few minutes to ensure it circulates throughout the system, protecting the engine from corrosion and moisture.
#9. Fog the Engine to Protect Internal Components
Fogging the engine coats the internal components with a specialized oil that contains rust inhibitors. This helps to protect the engine during storage by creating a barrier against moisture and corrosion, effectively putting the engine into a "hibernation" state for the winter months.
#10. Inspect Your Trailer Thoroughly
Don't overlook your trailer when preparing for winter. Check the wheel bearings, electrical wiring, and tire pressure to ensure they’re in good condition. Inspect the bunks (the parts your boat rests on) for wear and tear, and address any issues now. If your trailer has surge brakes, check the brake fluid level and top it off if necessary. Taking care of your trailer will ensure it’s ready for a smooth launch next season.
