## 🔌 Function

Senses the steering angle of the Aquamatic sterndrive at its steering arm and displays it on a helm gauge, so the operator can see where the drive is pointing when manoeuvring, docking or steering from a second station.

## ⚠️ Common Signs of Failure

-   Gauge needle stays at zero or does not move when the drive is turned
-   Reading drifts off centre or no longer matches actual drive position
-   Erratic or jumping needle from a failing sender or a poor connection
-   Corroded connectors or damaged wiring at the sender on the drive
-   Gauge fails to illuminate or read at all when the ignition is switched on

## 🛠️ Service Notes

-   Order by installation type, not by weight: this is the sterndrive kit and 1140465 is the rudder kit, and only 25 grams separate the two
-   This kit carries the connection parts for the drive steering arm, which the rudder kit does not
-   Zero the sender with the drive held dead ahead so the gauge centres correctly
-   This is the drive version - 1140465 is the kit for rudder installations
