ignition switch woes

[oxlacey]

The ignition switch plastic nut is cracked so it won't tighten.  I'm sure I'm on borrowed time.  Anyone know of a wiring diagram, part # for switch replacement, size of the plastic nut?  The key doesn't turn so easily either so is there something i can do to make the key turn easier?

You can try liquid graphite. Put a couple drops on the key and slide it in and out of the slot. See if that helps, usually takes care of it.

What motor is it for? Wiring diagrams for the OMCs are fairly simple to follow and wiring up a new key switch is not too difficult to swap out. If the key doesn’t turn easily, I am wondering if corrosion is the cause?

ok, nothing tricky evidently.  3 wires to the ignition switch.  Hot (RED) goes to common.  Run (PURPLE).  Start (YELLOW).  I do have additional wires to the switch that I wish the Vendor had provided instruction:  yellow/stripe, black and another black wire.
