Type of spark plugs

[mav6759]

Does anyone know what type of spark plugs are used in a 115hp, 1977 Evinrude outboard. The motor came without plugs and I have no idea what type of plugs go with this motor.

Thanks,

QL16V Surface Gap or QL77JC4,if you use the QL77JC4 the gap is 0.30

Champion ONLY is recommended,the QL16V is the preferred plug.

Those older motors don't usually like the NGK or other brands...
