Dealing with oil changes then is not worth it.Īnother reason to change your oil in the winter is that old oil has corrosive properties in it.

Plus, when the season starts, I’m ready to get on the water and have some fun. If you do it yourself, you’ll find many of the parts going on sale around the winter too. You’ll often find many dealerships willing to do an oil change with winterization combined for cheaper than it usually costs to get just the oil change in the summer. Not because it’s better but because supplies or labor to get it done is cheaper in the winter. I usually do my oil changes during the winter. Should I Change My Oil In My Jet Boat When I Winterize It? Just make sure to keep it somewhere ventilated and somewhere a smart charger can charge it. If you can store the battery somewhere warm like your garage, then do that. For solar chargers, you want to buy 10-watt ones with a built-in tender like this one on Amazon (Amazon Link Ad). You need to keep the battery active and using a smart battery charger (Amazon Link Ad), or a solar charger is the best way to do this. Flipping the battery switch to off is not good enough. Super Important – You need to put your battery on a charger or use a solar charger when you’re not using your boat. Just make sure to put them back in before going into the water.

Keep in mind boats are like a giant bucket, so rainwater can fill up the hull if you don’t take the drain plugs out. I’ve seen people not do this and have the boat sink on land. With the boat on land, make sure to take the drain plugs out. They like the taste of rubber but not the taste of the WD-40. This is to stop corrosion but also to keep mice away. I also like to spray down the whole engine compartment with WD-40. You can get this at any boat or camping store. You’ll need at least 1 gallon of the Pink RV Anti-Freeze per engine. Stick to Marine STA-BIL like this stuff on Amazon (Amazon Link Ad). Make sure to add some STA-BIL to the gas to keep it fresh while it sits for a few months.

Here is a great video that shows you how to winterize a jet boat. The intercooler for sure needs to be flushed out, and many jet boats have a dedicated port for that. Not only that, but if your jet boat has a supercharger, it also has an intercooler that is cooled by outside water. While the engine doesn’t take in the water, they still take in water to cool and muffle the exhaust. So they don’t take in any water, unlike the Yamaha Jet Boats. Some jet boats like Sea-Doo, Scarab, and Chaparral use a closed-loop cooling system. So you must get the water out before it gets cold. This water is located in tight spots, and if the water doesn’t have enough room to expand, it will grow and break your engine apart.īreaking the metal of the engine block or exhaust is not good as it can destroy them. The problem with water is that it expands when it gets cold. The biggest reason you winterize any boat is to get the water out of the engine.Īll boats use lake or ocean water to cool the engine. This could be where the confusion comes from. Jet boats do need to be winterized, but it’s not as involved as other boats. For some reason, people think jet boats don’t need to be winterized.
