Proper plugs for 5.5 and 55

[338ftw]

What would be the correct plugs for a 1966 5.5 and 1976 55? Both have champion CJ6 plugs now.

1964 was the last year for the 5.5 model and uses J4C------Make sure thermostat is not stuck open.------And CJ6 is the wrong plug for the 55 HP model altogether.----Try L77J4C for that motor.
