2005 Yamaha F225 Making Hissing Sound. The sound resembles the sound a motor makes when the spark plug is not tight, the sound apears to be comming from under the flywheel on the oposite side that the VST tank is located. The fuel rail and injectors seem to be tight. I have it on film cant figure out how to attach video of the motor running.
