So, I am in the process of completing the reassembly of a 1997 Seadoo GSX with 787 dual carb engine. This ski blew its MAG (front) piston either due to a lean condition (that's what I think after cleaning out the carburetor filters) or from excessive cylinder wall clearance (assessment of Fullbore.com, the company that did the boring/honing work for me).
Anyway, the catastrophic failure happened on June 10 of last year. At that time there was still 10 gallons of freshly pumped Non-e Rec 90 mixed with oil at a 40:1 ratio (We weren't sure if the oil pump was working, so we decided the lesser of two evils was double oiling and possibly fouling the plugs rather than killing the engine due to lack of oil). The ski has been stored in a garage with the fuel in the tank since then until about beginning of March when it came over to my place. Fast forward to yesterday, I pumped the 10 gallons of remaining fuel out of the ski in order to remove the fuel tank, make sure it was clean, etc. Now I have 2 5-gallon cans of fuel that I would like something to do with. In order of preference I would like to:
1. Pour it back into the ski and run it.
2. use it in my generator, power washer, and other assorted lawn equipment. This will take a bit longer as I don't typically go through more than a couple of gallons a month...
3. use it mixed with fresh fuel 1:1 (meaning half old fuel, half new fuel) in one of my seadoos (I have 2)
Can you all give me your opinion as to whether that fuel is safe to use on carbureted engines (all my yard equipment is carbureted), and how much longer do I have to do something with it before it goes bad? The fuel doesn't smell off or varnishy, but I am willing to dump it if its useless.
Thanks in advance for replies.
