Reply To: Stripped Spark Plug Hole?

[Bob Wight]

Mumbles is correct about the type of thread inserts you have to use for this repair. I used one of these on a stripped plug on a ’72 Evinrude 25hp and it worked perfectly. As an alternative, here’s a link to a list of parts for 1955 Evinrude and Johnson 3HP. They have a used cylinder head for $10 and I believe it will fit your 1954 model.
