Mercury marine.. Have your engine serial number, go to their website and place your order...

Or are you looking for this?

As it's useless, I have removed it...

what do yall think about the seloc manuls advertised on this web site. is there enough info for a 23 year automotive mechanic in them to saftely work on a 40 hp merc? plus their cheaper and ill need the extra cash for parts

I'm no expert but, the experts on this forum don't recommend seloc or clymer manuals. Too general and too many models covered. Try ebay or kencook.com. Hope this helps.

Either buy the manual or look at the drawing I posted... If that isn't a wiring diagram, what is it?
