Re: Need wiring diagram for my 50hp Johnson
Minority opinion:
To be fair, the Clymer manual has over 90 pages of wiring diagrams including one for your motor. They are black and white, but quite usable.
The large Clymer manuals are very helpful for general purposes across a wide selection of motors, and often have updates which could not possibly be included in the copies of the original factory service manuals.
