Reply To: Martin “60” spark plug

[JOSEPH BRINCAT]

Good “catch” Tubs… Yes, that could be a problem with the Martin. It sure is with the Evinrude Zephyr and their close-fitting shrouds. Although Champion makes a short body plug, the terminal is not threaded to take a nut and ring wire terminal. I found that NGK does make short body plugs with threaded ends (although metric thread) . I use the NGK  BM7A in my Zephyrs , the heat range seems comparable to the Champion “8” .    If you need to change from the push -on terminal to a nut, you will need to look for the correct metric thread.
