-   1.402 kg

## 🔌 Function

Manages and coordinates the engine or control system functions across a triple or quadruple engine installation.

## ⚠️ Common Signs of Failure

-   Control or synchronisation faults across the engines rather than on one engine alone
-   Stored fault codes pointing at the control unit or its communication link
-   Warnings or instrument readings dropping out intermittently
-   Water ingress, corrosion or a green deposit in the connectors
-   Unit not waking or communicating at all when the system is powered up

## 🛠️ Service Notes

-   Confirm the installation is triple or quadruple before ordering, as this unit is specific to those layouts
-   Check supply voltage, earths and the communication wiring before condemning a control unit, since most faults blamed on one are connector or supply faults
-   A replacement unit may need configuring to the installation, so plan for that before the boat is needed
