I top off the tanks in my Snow Machines as well as my River boat, at the same convenient gas station Northbound on the Parks hwy.. This fall when I was putting my River boat up, I emptied the two 15 gal plastic barrels I use for gas tanks. I had a bit over a pint of rusty water in each tank... I can see water infiltrating through the Bungs on top if they are not screwed down real tight, but even if rain somehow got in through the barrel bungs, that still doesn't explain the RUST in the water in plastic barrels... Fortunately I have a top of the line filter between the gas tanks and the motor, as well as the in-line filter on the motor... Earlier this fall, after the Boat had been put up, my grandson and I went to work on the snow machines to make sure they were ready... We started and ran all of them... That was before the real cold temps.... this weekend when we were thinking about taking a ride, my Skandic would not start... wasn't getting any gas.. I suspected frozen lines and dumped in a dose of iso-heet... The next day, after grinding on the starter for an excessive period of time, we finally got enough gas into the cylinders to burp and fire... it took several starts to get it to where it would idle on it's own... Has anyone else of late had water problems in the gas in their toys...?????
