I'm trying to figure out how to read the wiring diagrams.

When it says "Bilge Pump(Brn+Brn/Wht+GND)" that should mean three wires right? A brown, a brown with white stripe, and a ground?

Then what does "Blower(Yllw-14+GND)" mean? Does the 14 represent gauge or a color code (yellow 14)?

Last, are there wiring diagrams for the motor itself out there? I'm trying to figure out what all the wire color codes at the starter are.

I believe you're right on the first one. If I still had my boat at the house, I'd check for you. I'll check next time I'm down at the marina.

The second one, is yellow colored 14 gauge wire and a ground. I believe they labeled wires that were a different gauge than the standard wires they normally used (as a way to tell them apart).

There are mercruiser wiring diagrams, in the service manuals, which you should have access to. It might take a little bit of searching, but I believe it's in the electrical section. Or it could be in the ignition section, I can't remember which.

Thanks! I just spent an hour pouring through them and I think I found everything I need to figure out the entire 'non-Mariah' portion of the electrical system. I really wish there were detailed diagrams out there on how all the Mariah accessories are supposed to be wired in these things. I get confused on how all the three position switches are supposed to operate and I have a few hanging wires.
