CANBus Extension Harness Length

This system controls 2x Mechanical Engines and 2x Mechanical Gearboxes. It connects via CANBus to 1x Flexball 4500 Single Throttle Station.

The 4500-MM21 system is multivolt 9-32V. The 2x actuator boxes are mounted within the engine room and 2x morse cables (per actuator box) are connected between the actuator box and the engine throttle and gearbox actuator for both the port and starboard engine. The 4500-MM21 system also has the ability to override the electric motors and move the levers on the side of the actuator box by hand in the event of a power failure, so you know you will always be able to get home.

The 4500-MM21 kit includes everything you need electrically. The only component not included are the 4x morse cables which connect between actuator boxes to throttles and actuator boxes to gearboxes. We always highly recommend these be made locally to custom length.
