    Forgot to mention that I change my fuel water separators in the spring since I run the cocktail through the engines when winterizing. Probably could change them after running the cocktail through but it's just the way I do it. I agree that the use of ethanol is a scam. What's worse is the price they charge for so called "Marine Fuel" that is available to them without ethanol, but they choose to sell us the other crap to make a few bucks more.

    Methanol = Water -- so with this in mind.
    1 I keep Fuel tanks as full as possible - now this 100 / 125 gal per side. More fuel / less condensation / water that can be absorbed by tank.
    2. Kept in Marina Yard all winter (Nov till May)
    3. Change Oil either Nov or Spring -- need to remove condenstation from there as well
    4. Treat Gas before having boat pulled.
    5. Winterize boat in water except for outdrives - Run in yard and filled antifreeze
    6. Pull batteries and keep them charged over the long / cold / winter (well not so cold this winter)
    7. April - replace batteries - hook up hose to out drives and start engines --
    ****** No Fuel / Start Problems
    8. After in water at dock -- Change Fuel Filters (Generator on Tank and both "Cool-Fuel" Filters and screen" **** Remember Methanol acts like a detergent and will clean your tank and fuel lines ****.

    Eventhough Mercruiser "Cool-Fuel Filters and Screen" can run about $70 per engine -- it is much cheaper than engine repairs. Water will cause your Engine to run Lean - which may cause you to burn holes in your Pistons, etc. ----- $$$$$ Very Very Expensive Repairs.

    I have seen many boat owners add Fuel Filters with visable bowls that will allow them to drain the water filtered out the bottom via a stop cock. This can run about $90 per filter / housing + Installation.

    So in six years you never had a carb issue? Do you use an additive? Are you 100% certain your usual fuel has ethanol? The reason I ask is the signs say "up to" the amount of ethanol.
