Re: 1995 force merc... CUTTING OUT

Start at the gas tank and work your way throught the fuel system and check to make sure that you have no air leaks in the fuel line or fuel pump.

Next disconnect the battery!
Check all of the wiring on the engine one by one to make sure there are no loose wires, bare wires or ground wires in the engine wiring harness.
While checking and tighting the wires gently wiggle the crimped connections on the wire ends to see if any of the crimps are loose or broken.
Clean any corrosion from the wire ends and retighten.
Take your time doing this, it is easy to miss a loose or bare wire.

If the wiring and fuel are ok, you may need to check the engine for spark at each cylinder.
If so use the "search button" at the top of the page and type in "check engine spark" or something simular for your type engine.
I'd recomend removing the propeller when doing a spark check. (saftey!)
Good luck!
