This system controls 1x Electronic Engine and 1x Mechanical Gearbox. It connects via CANBus to 3x Flexball 4500 Single Throttle Station.

The Flexball EM systems are the ideal choice for upgrading unreliable throttle controls. Compatible with a wide range of electronic marine engines, including Caterpillar, Cummins, Yanmar, FPT, Doosan, and Hyundai, these throttles are suitable for both pleasure and commercial vessels. Whether you own a trawler, pilot vessel, commercial fishing vessel, or tourism boat, Flexball systems offer reliability and performance.

The 4500-EM13 system is multivolt 9-32V. The actuator box is mounted within the engine room and connects electronically using fly-by-wire to the engine throttle and mechanically to the gearbox actuator.

The 4500-EM13 kit includes all components required for connection, except for the morse cable required to connect between the actuator box and the gearbox selector, which we advise be custom-made to specific lengths for the vessel.

All Flexball 4500-EM series throttles are supplied standard with a “start interlock” safety function to ensure engines will not start if the gearbox is in gear. This Italian-designed and built system from Turin, Italy, is a quality and reliable solution.
