1963 18 hp evinrude point gap

[squid121]

My manual says if the motor has flywheel cd breaker points the gap should be .012 (used) all other point gap systems should be .020. My question is which point gap system do I have ? The points are under the flywheel but I don't know what the "cd" means. So I don't know which gap to use. Thanks in advance. Ronnie

If your coils are under the flywheel, you have the system that requires .020". If the coils are mounted on the cylinder head, you have the system that requires .012"...

CD stands for Capacitor Discharge, an electronic ignition system. The ones that used points were the first generation sytem. Later ones were breakerless...
