Twin Disc Quickshift and certain other model marine transmissions use Proportional Solenoids for engaging Forward and Reverse clutches. The proportional solenoids, along with Twin Disc proprietary clutch design, provide for smoother and faster clutch engagement. These proportional solenoids cannot be connected direct to battery power. Therefore, these marine transmissions are supplied with an EC050 Control Module.
The EC050 Control Module provides users of Quickshift and non-Quickshift Marine Transmissions with the means to operate the transmission. The module can receive commands from a mechanical lever with switches, or it can receive commands from a non-Twin Disc propulsion control system.
Quickshift model marine transmissions can be ordered with the standard EC050 Control Module for clutch engagement, or with an EC050 Control Module with Troll for both clutch engagement and Troll Mode. Both versions have the following features (except as noted):
