OK, so this is a bit strange. 2009 Mercury 4-stroke 9.9. Bought the motor used last year, and this is the first time out. Motor is seriously like new. I changed the engine and lower unit oil, cleaned the plugs, and gave it a good inspection. I've had it running a total of at least an hour before taking it out. Brand new Attwood 6 gallon tank. Brand new fuel line. New fuel connector at motor. Tank sits in the aft locker on a shelf. Fuel line runs up about 10", 3' horizontally (including the bulb), through a barbed bulkhead fitting, 16" downward to the motor.
Had to motor for about an hour on Friday, and it ran perfectly. Started and stopped about 4 times when needed without issue.
Saturday we had to motor for about 45 minutes or so, and she would try to die every few minutes. Would give the bulb a few slow squeezes and off she would go.
Same story on Sunday during 30 minutes or so of motoring.
Inspection of the hose/fittings netted no visible issues. All hose clamps are tight, connectors were solid with no leaks. Plenty of fuel in the tank, and the line inside the tank appears to be fine.
Were the installation at fault, I would think problems would have popped up on Friday.
Input is appreciated.
