    Don't Treat Your Fuel Prior To Winter Storage? Here's What You Can Expect

    I picked up a couple of used STXs a month ago. They have not been run in several years, and it's pretty apparent that they were not prepped for storage.

    I siphoned the remaining 'fuel' from the tanks:

    The brown gunk has the consistency of gasket sealer.


    I pulled the siphon hose from the tank and this brown goo covered the outside of my siphon hose.


    I lifted the JetSki with my forklift to make it drain faster. I stopped the process when I saw this slug of gunk moving through the hose.

    Yep, experienced that. And it drys to a hard resin type substance that is a bugger to get out and off everything. The only 2 treatments I HAVEN'T had problems with are Stabil and Startron.

    Well, perhaps my title was a little extreme. However, having bought a bunch of used 'Skis (18 to be exact), I can tell you that most owners never realize that their last ride is actually the last. Most plan to ride again in a few months and just put it away in the backyard or driveway. When next season rolls around, life happens. Accident, illness, loss of job, new job, divorce, wedding, (in my case, the lake dried up!). One winter turns into two, then three...

    The point is to run stabilizer near the end of each season. I've gone a step farther. I now drain the fuel out of my 'Skis at the end of the season and then run them on avgas for a few minutes on the hose to make sure the fuel systems have fuel that I know will be good for years.

    I have seen fuel so varnished and thick in the bottom of the tank that I had to put in acetone and let it sit a day to break down. I've also seen a few occasions where untreated ethanol fuel "phase seperated". It looks more opaque like milk.

    here's a tip for those getting started on wrenching

    don't let fuel or oil of any type touch your bare hands

    skin is not impervious, as people in the gardening business that have used roundup are starting to discover.

    you will suffer the effects as it's cumulative

    and for pete's sake Steve, your fingers are not cared for well. Get some lubriderm and some soak gloves my friend.

    My doctor advised me a few years ago to do something about my lung exposure to exhaust. Told me my lungs were damaged from over 20 years of driving in NYC traffic

    Luckily my lungs are kinda on the large size ( those that have them always need "long plate" x-rays)

    I stopped working on two strokes a couple of years ago because of this

    I have chronic bronchitis/COPD developing now and its not fun. The last ten years being in the ski business didn't help much

    These days I only work on 4 strokes and I always wear nitrile gloves when working around fuel/oil

    to dispose of such syrpy looking crap, mix it with cat litter for disposal

    I had an stxr sitting for a few years kind of forgot about it. I recently started going through it and found a few gallons of fuel in it which melted all the rubber parts off the fuel level sender.

    Yuk! I bought a lawnmower years ago at a yard sale guy said it used to run… When I got it home and took the carburetor out the gas was hard as glue. I got it running but it was kind of a pain.

    the smell of old gas reminds me that I should be thinking about retiring soon, before I start smelling the same way
