Neutral Switch Shift for Mercury
This neutral switch shift assembly, part number 8M0052939, is a replace component for Mercury outboards, functioning as a shift interrupter to allow smooth gear changes. It is compatible with Mercury 135HP EFI Verado and V6 2.5L models, serving as a direct replacement for OEM 8M0052939.
Overview
This neutral switch shift for Mercury is an ignition interrupt switch that momentarily cuts the engine spark when shifting out of neutral, reducing load on the gears.

Good To Know
Q: Is this the same switch for the Verado and the older V6?A: The part number 8M0052939 is specified for both Mercury 135HP EFI Verado and V6 2.5L models, but always verify your specific serial number because some improvements were phased in.
Q: Can I replace this without pulling the lower unit?A: Yes, the switch is mounted on the powerhead or bracket and is accessible with routine engine work, though you may need to disconnect the shift cable.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
