The question you didn't answer though is What do you do to get it running good again? |

Yes. It will run fine for a few days and then it starts acting up. Coil was replaced 12 years ago.

So what do you have to do to get it running again? Just reset the gap, clean the points, replace the points ? |

No. Ballast resistor not bypassed. Coil is stock.

Are you missing the ballast resistor? is it there but bypassed? Is the coil stock replacement or something else?
Too low impedance in the system will pull too much current than points can handle for long. |

I would determine exact cause of failure before making any system changes.
Check the spark strength, could be coil. Timing? Or ballast resistor. Or carb . . . You could start by checking voltage at + side of coil. |

I have a 1986 Martinique with a 351 pcm engine. We set the points to proper gauge and 3-4 days later engine starts missing with some backfiring and then boat won’t start. Considering electronic ignition but not sure it’s the best way to go. Any help appreciated. Thanks.
