Sparkplug Numbers Question?

[Boilermaker]

I have a 1978 115HP Johnson.<br /> The manual calls for L77J4 Champions. <br />Is this basicly the same plug as the L77JC4???<br />I was at Walmart the other day & they had a bunch of the L77JC4, but no L77J4.<br /><br />Thanks

Same thing. They added the C when they went to copper plugs.

The QL77JC4's will work also. The Q indicates a noise suppression sparkplug. I get them at Walmart too at only $1.87 each for either one.

The advantage to running the (Q)L77JC4's over the L77J4 is that the (Q)L77JC4's are available and the L77J4's are not available.<br /><br />The only disadvantage to the suppressor plug is that it's slightly more money.
