-   Mechanical interfaces match the specified linkage and fuel-control travel
-   Engine type, serial number, rated power and governed rpm are required for correct selection

-   Inspect linkage freedom, return springs and fuel-system condition before replacement
-   Engine type: Volvo Penta mechanically governed D5/D7 diesel

## 🔌 Function

Sets or transmits the specified governed-speed command.

## ⚠️ Common Signs of Failure

-   The engine cannot achieve or hold the specified rated speed
-   Speed response is delayed, erratic or affected by vibration
-   The control is incorrectly matched to the required rpm
-   Linkage travel or internal movement is restricted
-   Replacement is required after calibration cannot be restored

## 🛠️ Service Notes

-   Check the replacement carries the part number for your engine or drive installation before fitting — controls are matched to the system they work with and are not freely interchangeable
-   Note how the original is connected, routed and adjusted before anything is disconnected, and label the leads or cables as they come off so it goes back exactly as it was
-   Keep electrical connections clean and dry, seat connectors fully home, and route cables and harnesses clear of heat, moving parts and standing water with easy, unstrained bends
-   Mount to the original fixings and to the torque in the workshop manual for your engine, without pulling or springing the unit into position
-   Test the installation through its full range of function with the boat safely secured alongside before relying on it under way
