    Switching from a 2 stroke to a 4 stroke. Reading about all the ethanol problems with fuel injectors. What is the best solution??
    1. fuel additives or
    2. pay the price for gas at the fuel dock (supposedly doesnt contain ethanol)?
    Also, how much more can I expect to pay per gallon at the fuel dock? Thanks

    If I was to repower I would go with an E tec. That being said the gas at the fuel dock is questionable also because you don't know if they actually ever clean their tanks the gas in Dana point is cleaner than the gas in Oceanside I don't know about San Diego also the cost of gas at the fuel dock is about 1.50 more per gallon

    Fuel at the fuel docks in California has the same ethinol street gas has.

    Ninj is correct, all gas (other than race/aviation) has ethanol. If you use your boat often, no additives needed. I know Verados like 91 octane, other 4-strokes like my Suzukis are very happy with cheaper 87 octane.

    Wow, I always (maybe it's chgd.) heard dock fuel didn't have it, or is it less %. Either way sounds like everyone just uses the 'ol gas station fuel, with an additive or two, and follows all the usual procedures: run the carbs empty, run it often, don't use old gas, get a fuel/water separator.
    I don't know anything about "Ring Free" so I'll be researching that one today. Sounds like a Yamaha product.
    Thanks again.

    If you don't want to add ring free, buy 91 octane from Chevron. I use only 91 Octane from various brands for my Suzuki but manufacture said 87 is acceptable. I add Startron fuel Stabilizer and motor purrs all day long.

    Install an inline fuel filter/water separator. Add StarBrite StarTron to each tank of fuel.

    In mission bay gas price was 4.55 last Saturday, so it's .50 to .70 a gallon more, not a 1.50

    Keep 'em coming this is a great thread. Everyone has there "secret" formula for keeping 'em running strong.
    How about tanks? Poly Moeller, should I keep it full when stored (less condensation, but I e heard ethanol breaks down the plastic sides), or put it away close to empty?? Opinions??
    I just want this thing to perform for all its worth...both up front and in the long run.

    Ethanol can break down fiberglass tanks but never heard of any problems with plastic.

    Older plastic tanks are permeable enough that you may get the smell of fuel in an enclosed space. Don't know exactly how long, maybe 3-4 years now. but the new standard is much less permeable.

    IMO less than 8-10 months store it full. If its going to sit for much longer than that consider storing empty.

    Don't skimp on the quality and size of the filter/water separator.

    The problem with alcohol in fuel is it goes into the tank at 190 proof plus and from there absorbs moisture...boats generally have vented tanks that can't be sealed off so the best solution is to run it frequently(you can tell the wife I said so) or add a stabilizer.Once the alcohol has absorbed all the moisture (it's hydroscopic) it can and there are varying temps and moistures during the day night cycle it will precipitate water to the bottom of the tank when it cools and reabsorb more when it heats up.

    drive the boat often enough and you'll be putting "dry" gas back in that will absorb some of the moisture in the bottom of your tank keeping it to a minimum..so they are doing you a favor...fish early fish often...you just have to!
