Like the title says I'm looking to update/upgrade the magneto/points setup in my 1975 Johnson 15HP to a newer 1985ish CDI system. I ordered everything in that system but the flywheel off eBay. Now that I've spent the money, anybody know if it's possible? Did I waste my money? Will I also need the newer flywheel?
