The EC300 Backup Propulsion Control System provides fully redundant propulsion control of EC300 Power Commander systems with electronically governed engine and Twin Disc Quickshift® marine transmissions. Only the wiring to the marine transmission is shared; all other control devices are independent for primary and backup propulsion control.

The Backup is available for electronically governed engines that require a 4-20mA throttle signal. Ask us about other throttle signal options.
