Good To Know
Q: What are the symptoms of a bad neutral switch shift on my Mercury 250HP? A: A common symptom is the engine not cranking in neutral or cranking while in gear, which can cause sudden movement. Check the switch with an ohmmeter and replace it if the continuity does not match the shift lever position.
Q: Can I install this neutral switch shift without removing the lower unit? A: Yes, the switch is typically located on the shift plate or linkage inside the cowling, accessible without removing the lower unit. Always consult your service manual for the exact mounting location on your specific 6-cylinder model.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
