Spark Plug for Johnson 70 outboard ???

[spanboy]

What's the best spark plug for this 3 cylinder 1981 engine (Model J70ELCIM)? What is the recommended gap? An a general question, does the gap vary with the brand of the plug, type or is it fixed for a given engine?<br /><br />Thanks.<br /><br /><br />------------------<br />Spanboy

Hey, Spanboy. You want a Champion L77J4 gapped at .040.<br />Bon Voyage.<br />JB
