Alternatively if your idle mix is a touch on the lean side, it just doesn't have enough fuel to get you over the hump, so to speak.

Easy test for that - as you open up, prod the choke. If it roars into life, it's too lean. If it coughs & dies, you may be too rich as Alystra says. A simple minute turn of an adjuster screw(s) on the carb(s) will cure it.

Guys , firstly before you start going for it and adjusting mixture screws and timing etc etc you NEED TO KNOW if this is a FUEL problem OR an IGNITION problem . I agree a fuel problem the engine will slowly gradually surge and loose RPM and then cut out , by the sounds of things here this OUTBOARD is cutting out immediatly as someone has pulled the kill cord . You really need to get it into someone who can hook up the computer to it ( i can do that ) and simply do a ignition drop test on each cylinder and diagnose the problem properly before seriously causing more problems . Also its already been said it could be a fault in the stop circuit from the control box and the wiring is shorting out taking that wire to an earth cutting the ignition spark . Is this engine E.F.I or a Carb Model ? cheers Baz

Having used the boat last week I've got more of an idea of the problem.

When accelerating hard the engine splutters slightly before cutting out- when I noticed it starting to splutter I throttled back and all was well.

Does this info help- makes me thinking its more fuel related than electric.

Thanks for all your help
