I had some mechanical problems over the weekend. Put the boat in the water- went to start it up. The thing will start with a couple pumps, run for about one revolution and then quite. You can do this over and over again. Boat ran fine on Friday night- got to the ramp and it did this. It did it at home, same thing. I was thinking something is stuck open or closed; but I cant figure out why I can get it to fire; but not continue to run even when pumping the throttle.. Any help is appreciated.

Do you have an electric fuel pump? low pressure and high pressure, or if carbed maybe just low pressure.... check to make sure it or they are running when you turn key on... the fitting at top of the fuel pump, 2 pins can get corroded and not get any power, something to try, had it happen to both my motors last year.

I went in and did the diagnosis for the fuel system. narrowed it down to the relay- got a new one and it fired up. I also tapped on the outside of the card- so I may go back- put the old relay back in to make sure that was the actual problem. thanks
