Doing it Yourself

How to do it yourself

The first step to winterize your boat is to of course check the owner’s manual. Because all boats are different, you will want to ensure you are doing everything properly and that you are not causing harm to your boat. By following the owner’s manual you will know that you are winterizing your boat correctly.

The second step is to check your engine. You will want to make sure there are no damages. If there are, you will want to get them fixed immediately. Check for loose wires, cracks, etc. After that, remove all the water from the engine. Next, apply a corrosion product to the engine.

Next, add a fuel stabilizer to the fuel system and then run the engine for ten minutes. This will allow the stabilizer to diffuse throughout the system. After you’re done with that, replace the engine’s fuel filter.

Fourth, empty the freshwater plumbing systems. You will want to check any sinks or anything else that uses freshwater to ensure it is drained. Next, add antifreeze to the plumbing systems. Then remove all plugs to the drains.

Fifth, place a cover on your boat. Make sure it is a quality boat cover that can help protect against harsh weather. The final step is to place the boat into storage.
