I'm wondering if anyone knows the spark plug gap for the evinrude 15hp 15404s motor? The plug I found out it takes is a champion L86c or L82c. I have the L86c plugs
Do yourself a favor and buy NGK B7HS and gap to .030". Those '74-'76 9.9/15hp points motors have a 'low tension magneto' (whatever that means) and seem to like the NGK's much better.
