Parts Desk Insights
The strongest fitment cross-reference for 8M0235190 is the older 8M0037225 — if a customer has that number on their existing switch, 8M0235190 is Mercury’s current replacement. The most common issue is customers describing a trim switch problem without knowing the exact switch location or part number. Before selling, confirm whether the switch is cowling-mounted, remote-control-mounted, or dash-mounted, and verify the connector matches. Wiring and connector configurations are not universal across Mercury families.
