Full model list at the end of this description.

⚙️ Key Features

• Exact DPI-A drive application
• Measures transmission or drive rotational speed
• Factory electrical connector and sensing specification
• Supports EVC monitoring and control
• Installed in the gear-housing sensor assembly

🔌 Function

The sensor converts rotating gear or shaft movement into an electrical RPM signal for the transmission or EVC controller.

⚠️ Common Signs of Failure

• Missing or erratic drive RPM reading
• Transmission or EVC warning
• Shift-control fault
• Intermittent signal when warm
• Signal changes when wiring is moved

🛠️ Service Notes

• Note how the sensor sits and how its lead is routed before removing it, and support the harness so refitting does not leave the cable strained or rubbing
• Turn the sensor with a spanner on its hex only — never lever or twist it by the connector body or the wiring, which breaks the internal joint even when the sensor looks undamaged
• Renew the O-ring or sealing washer where one is fitted, and do not add thread sealant unless the manual for your engine specifies it; sealant on the threads can break the earth path of a sensor that earths through its body
• Tighten to the figure in the workshop manual for your engine — overtightening distorts the housing and shifts or destroys the sensing element
• Make sure the connector is clean, dry and fully latched home and check the pins for corrosion and spread — a poor connector accounts for a great many faults blamed on the sensor — then run the engine and confirm the reading or warning lamp behaves sensibly before returning the boat to service
