Your goal with a boat is to have reliable fun on the water, ditch any point’s style ignition and go with some sort of electronic version, if you’re on a tight budget, go with a GM HEI for about $100 brand new, or if you have more money and if your future sights are set on performance and possibly building more power go with the MSD marine ignition system, I have this on my jet boat and it has performed flawlessly.
