Why Replace the Speed Sensor?

A faulty speed sensor can lead to serious malfunctions on your jet ski: erroneous or absent speed display, untimely triggering of engine alarms, or loss of control of speed limiting systems. Common symptoms of a defective sensor are:

• Speed displayed as zero or frozen on the dashboard
• Engine fault light illuminated (ECM error code)
• Erratic cruise control behavior
• Unexplained power loss at high speed

We recommend checking and replacing this sensor during each pre-season service or after 50 hours of navigation, to ensure the reliability and safety of your Sea-Doo jet ski.
