I have been on many boat forum sites looking for wiring diagrams for the Mariner 25 EL outboard and found none, so to help others out I have made a mud map of one that has a harness to connect to a key ignition switch.
If you have any questions regarding this diagram or anything you would like to see on this site , please contact me.
I will do my best to help out.
The Black and orange wires from the CDI connect to the capacitors for the spark plugs in the diagram below.

A closer view of the orange and black wires.
magneto wiring from CDI and the blue sheath contains the green wires
A view of solenoid showing brown and black wires plus + battery connection.
A view of choke: blue to choke switch, black to earth.
To connect the harness to a Narva 64008 keyed ignition switch connect:
Red to power
Brown to S (start)
Blue to C (choke)
White to M
Black to MG (earth)
Leave " I " vacant
Green leave vacant
Pink to neg terminal of battery
To connect a kill switch: connect one side to White and the other to Black.
