went out today for about fifteen minutes and went back to the dock (the motor ran fine). i started it back up around ten minutes later and the engine would start and idle fine but when i put it into gear it would stall out. I found that only one of the three cylinders (the midddle one) was firing. Any sugesations of what this might be? The plugs are new and it has a new fuel pump. this was also the first time the motor has been in water in a few months.
