- MerCruiser McGill Shift Interrupter Neutral-Safety Shift Cut-Out Kill Switch 39670A22
- Tested & working!
- A tear in the shrink tubing around the connections, but this was pretty common on all of these that I have processed & seen because of how they oriented the soldered wires coming off of the tab connections in conjunction with how the wires were typically routed.
- Generally found on In-line engines late 1970's through the early 80's where the unit is mounted to a horizontal plate at the back of the engine which also has the reverse-lock assembly on that plate.
- Purchase with confidence!
