15hp conked out, family vacation...HELP...wife and kids rebelling....

[bluebrownie]

Hi, have a 1996 15hp gamefisher (merc/force)...on vacation with family, motor started running badly and finally conked out, won't start.
History: when start, no problem (up till this incident), idles fine. in neutral i can full throttle up... revs fine.
Whne I Put into gear, and i turn handle/throttle slowly, it bogs down... and stalls... when i quickly punch the throttle to FULL THROTTLE /WOT, bogs for second then runs fine...if i were to start out slowly and slowly increase throttle speed...it will conk out..so i punch it to full throttle to avoid the conk out. Now it won't start at all... any ideas????

FUEL PUMP PROBLEM????? thx guys

How long has it been sitting? Bad gas ? Dirt and gunk in carb bowl? Could be a host of things but it sounds like fuel/ carb problem. Never hurts to check the plugs could be fouling hope you get it going. Hate to hear you had to walk the plank!!!

sounds like a carb problem ..... you probably need to pull the carb off and clean it. Sounds like the slow speed circuit is plugged. In order for the motor to run it needs fuel and air, add air with no fuel and it boggs, add fuel and no air, it loads up. Sounds like you are lacking fuel at low speed and when you punch it, the high speed circuit is clear and it revs up.

Carb cleaning a couple months ago unfortunately means nothing, it only takes a little dirt in the tank, old fuel sitting, any number of things can clog a carb. I would pull it off and clean it.
