    Full tank to winterize?

    Do you guys fill your tanks and treat with stabil to winterize? I have seen different opinions. What are the major checkpoints to do a proper winterization?

    I use non ethanol gas and stabil. Fill it up and run it for a few minutes to get the stabilized fuel through the carbs.

    i put stabil in whats left run it through then drain the rest into my car. I dont like running 6 month old gas in the spring personally, especially in a modded ski.

    I empty my tank and run fresh gas in the spring.

    This is what Ive always done with my motorcycles as well. If you use non-oxygenated gas you shouldn't have any worries for 4-5 months of storage.

    I do the same thing.

    Where I'm at in south Texas, gas with at least 10% ethanol is all that is available. Even if I could buy ethanol free gas, I would still want to empty the tank and start with fresh gas in the spring.

    I feel both methods are valid and justifiable. Moral of the story, doing something is better then doing nothing. Just pick which method seems better to you.

    I do the following before winter. It may be overkill.
    1. Run the ski on land with the waterline adapter and flush the system for a few minutes.
    2. Shut water off and then open the throttle quickly a few times to blow out as much water as possible.
    3. Attach a funnel to a short piece of hose connected to the waterline adapter. Start engine and pour RV antifreeze into funnel. Continue pouting until you see the pink fluid come out the back.
    4. Shut off fuel cock and run it til it dies. I actually shut off the cock during step 3 to minimize the amount of time running the ski without water while the hoses / carbs run out of gas.
    5. Shoot fogging oil into the intake for the carbs. Remove each sparkplug and shoot some fogging oil into the combustion chamber. Reinstall sparkplugs. Crank engine for a few seconds.
    6. Remove all gas from the fuel tank. I use a cheap hand pump from harbor freight (http://www.harborfreight.com/multi-u...ump-66418.html). I run the gas through 'Mr. Funnel' filter to catch derbies and separate any water and then burn it in my truck.
    7. Remove the gasline going to the fuel filter and drain any remaining gas from the filter and lines.
    8. Use shopvac to remove any water from the bottom of the bilge.
    9. Let the ski sit open with the seats off in a area like a garage so that it can air out and let any remaining moisture evaporate.
    10. Cover it for winter.

    My .02 on sta-bil. I've taken apart carbs that were winterized with sta-bil that were not working right the next season. When I looked inside, I found that sta-bil shit gummed up all over the place more so than the gas. Sta-bil is a red/pink color, so its easy to spot. Save your money and run your carbs dry.
