Posted

A boat with an inboard engine can have tremendous benefits—but it can also require some special maintenance that boat owners need to be aware of. That’s particularly true when winter’s on the horizon and your boat has to sail through the cold months in the best possible shape. Here are some simple tips for winterizing an inboard boat the right way.

Reduce The Amount Of Air In The Tank

Just as experts recommend keeping a tank full of gas in the winter for your car, your inboard motor does well with less air in the tank and more fuel. Why? Because air has moisture. When the temperature dips, you don’t want all that moisture interfering with the proper functioning of your tank. When winterizing an inboard boat, make sure you have an engine full of fuel, because this reduces the amount of air left.

You should also add a fuel stabilizer designed specifically for your type of fuel. This will prevent any unneeded buildup in fuel lines. And keep in mind that now is as good a time as any to replace your filter in the fuel-water separator. Keeping your boat in the water can aid in the supply of water throughout.

Add Antifreeze For Proper Winterization

Ask around to make sure you use the proper antifreeze for your boat. Don’t be afraid to go to a marine store and ask for the proper “diagnosis,” so to speak. Picking the right product is essential and will yield the best results when winterizing your boat, not to mention the overall quality of your boat’s maintenance.

You’ll want to work with a warm engine (as you will with the next step) to facilitate the process of adding in antifreeze.

Change Your Oil

Changing the oil and oil filter is essential in preparing a boat for winter, which is why you should do it now. Think of it as knocking out two birds with one stone. This way, you can promote the health of your inboard motor, while helping to prepare it for winter. Keep in mind that you’ll want your engine warmed up. Changing the oil while the engine is still warm will help flush out old gunk and contaminants, which in turn makes the entire process easier. It also aids in the effectiveness of your winterization efforts.

Inspections For Long-Term Maintenance

Since you’re getting into the inboard motor, now’s the time to inspect areas like the exhaust system to ensure there are no cracks or leaks. You should also inspect the hoses for leaks, not to mention sealing off engine openings to make sure that your boat is properly prepared for the harsh environment that will come with winter.

Don’t proceed with winterizing an inboard boat without safety precautions, and make sure that you read any instructions thoroughly before you begin. Dealing with an inboard engine can be intimidating, but with the proper steps and the right products, you’ll do just fine.
