Fuel Problem, 1994 75 Mercury 3 cyl

[jandlwolverton]

Dealer has'nt been able to figure this out. Motor runs well most of the time, but will sometimes start cutting out, usually at medium to high speed. All 3 cylinders still fire, but the motor acts like its not getting enough fuel. I can choke it and pick up rpm for a few seconds. If I squeese the fuel line bulb it sometimes will straighten out, sometimes not. The problem disappears for no apparent reason, and will occur again, sometimes the next outing, sometimes not for a few months. The fuel lines, fuel filter and connections are good. The tank vent is clear. I run the boat year round, so I think gas is fresh and clean. ??? any ideas!!?

It could be that there is a speck of crud in the float bowl blocking the jets at random intervals or dirt in the tank blocking the fuel pickup.
