" i used the boat one day and it ran great, then next day i took it out and i had no spark at all, so i changed the coil, and still nothing....what else could be wrong?
possibly the points out of adjustment? "

"Points could be frozen open or closed, coil wire to the distributor could be shot.

I have a question for you, too. I have a 1974 OMC 120. I don't have any manuals and I need to know the gap on the plugs and points. Can you help me with that ? I'm not a member of this post, so if you have any info could you email it to me at [email protected] (""). Thanks."
