9.9 Evinrude (1981) spark plugs

[Jim Robbins]

Hi, I have a 1981 Evinrude 9.9 outboard motor ( E10RCID ) I think that the spark plugs that are to be used with this motor are Champion QL77J4 .
Can I use Champion QL77JC4 ? Will there be any problems that I should watch for? Thank-you.

Those are what you want, gapped to .030
