Need some help diagnosing a problem. I have a 1997 mercruiser 350 magnum tournament ski - carbureted motor and today on the lake it ran fine for about an hour then started to skip and misfire then idled very roughly and died - could not start it again. Boat did the same thing a couple of weeks ago and in between, I checked the water separating fuel filter and there was no water in the gas (it had a brand new filter from the beginning of the season), checked the fuel tank vent - and no clogs. I also changed the spark plugs, distributor cap and rotor (it has the thunderbolt electronic ignition), I also reset the timing and cleaned the spark arrestor - thinking it was starving for air. The fuel pump seems fine - it looks like it is pumping normally and I can see fuel going into the carb. The boat ran fine in the driveway all the way up to 4000rpm when I tested it, but today it died again on the lake after an hour or so.
At this point, I'm thinking coil?
Any other suggestions from those of you in the know?
Thanks.
