Good To Know

Q: What causes a camshaft position sensor to fail? A: Heat cycles, moisture intrusion, and vibration are the usual culprits on marine engines. Once the internal element breaks down, the signal becomes erratic or drops out entirely.

Q: Can I ride with a faulty camshaft position sensor? A: It is not recommended since the ECM may default to a limp mode or refuse to start. Replace it before your next launch to avoid being stranded on the water.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
