Working on an old Evinrude, 2 cylinder 4hp outboard. (E4RLCSS)
Specs call for Champion L77J4 spark plugs which I can't find anywhere.
A salesman suggested going with L77JC4
Will they work?
Cheers
Neil
I had to do the same thing although I check out equivalent from other manufacturers. I think there are charts out there that have equivalent plugs. But I do believe their recommendation will work just fine. Mine was a 1961 3hp evinrude.
