Here's a start;

What shape is the rest of the boat in? What boat? What motor? Depending on knowing that we may be able to give you some pointers.

Was the boat sunk or exposed to the elements. In either case, the motor is the least of your issues

I think you can buy the engine harness as a bulk wiring set, at least I have seen them online in the past.

You will still have to figure out the navigational wiring and anything else not engine related.

Agree. Make sure this thing is running and worth it, no major leaks, transom is OK, floor not spongy, etc. before you throw any money at rewiring it.

You can't just use automotive or house wiring either. Marine wiring is tinned throughout it's entirety.

Don't make patches in the harnesses, get replacement harnesses.

If there's a fire on a boat, there's nowhere to run!

I would check the condition of the engine oil and the stern drive lube. If either one looks like a milkshake, there's water intrusion.
If all seems ok, I'd get the engine and stern drive running on muffs.

You better check the bellows too.
