  • accelerator pump???-gctid804835

    Fired my boat up the other day on the hose...Launching next weekend and I have a problem...It's running great but when I go to give it gas it dies out....If I accelerate real slow or pump the throttle quickly it will get going and hold whatever RPM I go to...Seems to be more of a problem at low RPM. I changed the water seperater but not that little filter in the carb yet...Does this sound like a gummed up accelerator pump?

    In a panic this morning I one click ordered a new carb on the Amazon...Because it was $260 and a rebuild would probably cost me half that...Do we think the new carb will solve this? arrives Tuesday...Also, it's a Merc 350 with 2 barrel carb.

    Mainly because of time. Traveling all week for work and it's quicker to just slap a new carb on given that it's cheap enough. My haul is already scheduled and won't be able to get a new appointment for a while

      Does sound like the accelerator pump. With the engine off look down the throat of the carb while someone works the throttle forward. You Sould see a good solid spray of fuel being delivered.

        I've never remove the carburetor before. Is it just the bolts on the bottom and the fuel line and the wire for the electric choke. Simple? Then a new gasket when I put the new one on?
