🔌 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
