When winterizing your boat you also need to be aware of your fuel system. When you winterize you need to protect your internal surfaces, make sure water is not sitting in your fuel, and stabilize your fuel for winter with fuel additives. Water is harmful to a boat’s fuel. If you add Starbrite’s Gasoline Water Absorber to your fuel, you will remove harmful water from your fuel system. We also carry Starbrite’s Fogging Oil and Fuel Stabilizer to keep your fuel as good as new throughout the winter.
