Re: Evinrude 40 plug gap
According to the OMC manuals, you should have a Champion plug - one of five:<br />(Q)L77JC4 = .030<br />(Q)L16V = Gapless<br />L78V = ??? .030 is best guess bassed on other plugs for that motor recommended by Champion<br /><br />If you have NGK's:<br />BUHXW-1 = Gapless<br />B7HS = .030<br /><br />If you have something else in there, you may want to switch to one of these. I have no way of cross referencing the Autolite, but I know they tend to be a popular option as well.<br /><br />Hope that helps
