I need a manual for a 1973 Mercruiser 888 serial number 3440268. I have the Seloc Stern Drives 1964-91 Repair Manual and Seloc On-Line, but neither are specific enough. What I need today is the wiring diagram for the ignition system and the pump solenoid. I rebuilt the engine and put in two new solenoids, but I still can't get it to start from the ignition switch and I want to double check the wiring to pump solenoid. Any help would be appreciated.
