Hi Guys
I recently purchased a 1987 Chapparral Model 187 outboard. I need to find the wiring diagram. The previous owner disconnected many of the wires to add fishing equipment, radios etc. He is not an electrician. The running lights are not working,many fuses are missing and I have 5-6 wires that are just hanging. I need the diagram for the fuse box to all accessories. Appreciate any help so you can point me in the right direction. Thanks, Tym

Never existed.

Look at the factory service manual for the outbound. It will have motor and control related wiring schematic

The rest of the boat, you will need to trace wiring

Start pulling and tracing one wire at a time, it's the only way to go.
