I just found out after trouble shooting that I have a large amount of water in my fuel tank. When winterized each year (boat is 10 years old) I would put fuel conditioner in and make sure the tank was full. Every spring I would replace the water fuel separator filter. This has built up over time and or possibly some bad gas at that fill up. Is there anything you can add when fuelling up to minimize or eliminate this problem in the future? What do others do?
