Firing Order 5 hp 4 cylinder

[Uxboat]

Evening All,
Iam trying to put a old 5 hp 4 cylinder Evinrude Zephyr back together, finally with the help of a local old engine guy I got the last piece.Now to try and start it I need the firing order as all the spark plug leads are hanging loose.Anybody out there know which spark plug wire went where ? Thanks to everyone for looking.Mike

As I recall, two cylinders fire at the same time, but that's not much help is it? Post your question over at the antique outboard club, aomci.org Lots of Zephyr nuts over there.

Top/Bottom. Simple as that. It is an opposed quad, meaning the two top cylinders fire at the same time, and the bottom two fire at the same time, 180 degrees opposite the top...
