Hello Everyone- I have a 1997 Sea Ray 190 Signature with a 4.3 Lt engine. The engine is brand new last year, and I mean brand new. the only thing that is used is the card, everything else is new. The last 2 weeks when I start the boat at the Marina it will run for 30 seconds and shut off. It will start rite up again and do the same thing. I can do this all day long. I changed out the old gas - thinking I had water in the tank. I cleaned the tank completely. Put new High Octane fuel back in. Changed out the water fuel separator filter. Changed out the small inline filter just where it goes into the carb. Still does the same thing. Runs for 30 to 40 seconds and shuts off. I have also checked the fuel fill lines for obstructions and there is none. I'm at a total loss. Could it be the fuel pump? any advise or suggestions would be great. The fuel pump in not in the tank.
