Many (if not most) early outboards used a common spark plug of the time as used on very popular automobile Model T Ford
Louis
edit…a quick check for Model T Ford spark plugs at Mac’s gives a
price range $4.95 to $38.99…I am fairly certain the Model T spark plugs are correct fit. The low price plugs will work as well as high price
spark plugs…difference is functional vs original look. Choose wisely.
Welcome to Antique Outboard hobby
I am corrected on the spark plug type
Both Model T Ford and Evinrude Row Boat Motor applications
use the same selection of spark plugs offered by Mac’s
Same plugs Same price.
Turst me on this BUT look it up on line to verify.
