1985 omc 3.0

I sure could use some help. Went out on the big lake for a test ride on Sunday ( first time out this year ) . Boat started find ran very well , for about 1 hr. Started going back in at 3/4 open tack started jumping all over the place then engine started runing rough, then stoped.

points where new - shot now,

Where dose the coil get it power from when engine is runing?
If I were to put a balest resitor in where do they go?

When new ignition points burn out prematurely, two things come to mind:

The points somehow got grease or dirt on them.

The points were set too close. (Dwell would have been wrong)

Or both of the above.

I'd also put in a new condenser, this is there to stop the unwanted arcing between the points while they are open.

All replaced new at same time. Don't think grease on them. Thanks for the help I will have to keep look'in

Put in another (New) set, many folks seem to be suffering from quality issues these days especially those with the solenoids. Set the dwell, check the timing. You should already have a resistance wire in there coming from the alternator, possible a bad start solenoid could be giving the coil a full 12V all the time bypassing the resistance wire?

I can't wait to get home I think it could be a lose wire by the key. Thanks Bob I will also look at that
