For use with EC300DP Power Commander and Twin Disc marine transmissions

The EC300 Backup Propulsion Control System provides fully redundant propulsion control of EC300DP 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.
