Spark Plugs- 1967 6hp Evinrude

[matt-fortmyers]

I'm replacing the plugs on a 1967 6hp Evinrude. I purchased it used, and it came with plugs that say "Champion 5843." Are these the correct plugs? Should I purchase an identical pair to replace them? I'm a total novice at this so any advice is appreciated. I could use advice on setting the gaps, too. Can I purchase the plug at most marine supply stores?

Best,
Matt

Champion J6C, or, NGK plugs B6S are the right plugs for your motor gapped at .030.

Only Champion J6C or J4C, gapped at .030", as old cat says. The J4C is better for extended high speed operation, the J6C for all-round operation.
