Hi folks!

I just bought a boat with a mariner 30hp outboard and I can't find a
manual for it anywhere.

Specifically, on the front of the motor near the choke and whatnot there
is a 1" round threaded cap covering some sort of electrical connector
and I have no idea what it does. Any ideas?

If you don't get an answer here, manuals (don't know how good they
are) can be found at:

You can sometime find various "factory manuals" on E-bay.
