Good To Know
Q: Will this neutral switch fit a Mercury 150HP EFI Verado 4 CYL with a serial number after 2005? A: Yes, the 8M0052939 replaces the original switch across most Verado 4 CYL production years, but confirm your serial number against the OEM cross-reference before ordering.
Q: Does this switch require adjustment after installation? A: No, it is a bolt-on replacement with a fixed plunger travel, so no adjustment is needed once it is secured to the shift linkage.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
