Just picked up two 2014 90 horsepower Sparks. the original owner told me that he has been running what he thinks is probably E85 fuel. That confused me. Can it even be possible to run E85 in a stock 90 horsepower Sea-Doo? before I refuel I have to get this straightened out. My thought was if it's a stock 90 horsepower you run high octane unleaded fuel. could this guy have been putting the wrong fuel in there and if so would it even run properly?

Thanks so much for your help.
