Ran out of fuel, had to be towed to the marina, gas pump attendant asked how much I wanted, tole him 10 gallons. Noticed that the boat ran poorly, it was late so we pulled it out of the water and went home. I called the marina the next day, they said it was clearly stated that it is unleaded gas. After talking with others that grew up around boats they were surprised that the attendant didn't ask what type of mixture we needed. Anyway, I already had an appointment with a shop, so I am waiting for an answer back. I am hoping that there isn't much damage, just looking for an opinion. If it was running hot could that be why the power was low?
