The best way to stabilize the gasoline in your boat [SOLVED]

Thanks for the question Ron. At a minimum, add 1 ounce of Marine PRO for each gallon of fuel in the tank. It’s also a smart idea that you run the treated fuel through your entire fuel system and into the upper engine before storing. After adding Marine PRO to the fuel, run the engine for at least 10 minutes to pull the treated fuel through the entire system.
