95 Merc 225 Offshore, runs very well untill warmed up then stalls. I can put in neutral and clear carbs and it will go approx 5 miles then stall again. It never dies just seems to foul out plugs. Has been at a merc dealer for 1 month with no cure. Dealer replaced plugs, checked fuel lines, replaced thermostats, popet valve, tested stator, swapped ignition switch, tested fuel enrichment valve.. Help!!!!!!

It only stalls after it warms up. Runs strong until then. Any suggestions?

If it only happens at idle I would suspect a low voltage problem usually caused by a stator or trigger winding heating up and breaking down, the free revving increases the voltage and cleans the system up and it runs OK for a few more minutes till low voltage causes the engine to load up again call the dealer and tell them they missed the problem, do they want it back or must you find someone else to repair it the lest that should do is get you to the front of the line and have them recess the first bill, if not you need to call Mercury Marine and ask if the have a servicing dealer in your area

Thanks for your reply, but it does not happen at idle it happens while cruising 3-4 k rpms. It falls flat and will not accelerate again untill after clearing carbs out.

thanks

Has anyone had any experience with an ignition coil not firing correctly after engine warms up?
