This may help as well. These are the Mercury standard wiring color codes. You can also order a manual for your year that will have all the wiring diagrams. I'd recommend getting hold of a wiring diagram of some sort before trying this. You can get the manuals on Amazon or find them online as turtles suggested. Keep us posted on how it all goes.

I had to use a meter and check for continuity through the key switch, in the off, run and start positions, then using the wire color chart I was able to determine where each wire needed to be. Good luck you can do it !!!

Re: 1965 Mercury 65hp

I just got a boat with A 1965 MERCURY 650 65HP ON IT. When I restored the interior of the boat, the fuel line was bad so I took it out and threw it away, not thinking about the fittings to the motor. Can anyone tell me where I can get a fuel line fitting for this motor, or even show me a picture of what it looks like? I cant seem to find anything about it online.
