Flexball Electronic Throttle Controls offers the latest electronic technology to control marine engines and gearboxes. Extremely responsive and reliable, the Flexball system is an alternative and perfect replacement to the more traditional morse cable or hynautic control systems. The Flexball 4500-MM11 is a system suitable for 1x Mechanical Engine and 1x Mechanical Gearbox. It connects via CANBus to 1x Flexball 4500 Single Throttle Station.

This system will suit any make and model of marine engine and marine gearbox. The Flexball 4500-MM11 offers extremely smooth feel and operates providing extreme precision control all the way through the rpm range from idle to full throttle. The feel the the Flexball throttle is much more refined than any hynautics or morse cable system and is a lot more responsive to small adjustments.

The 4500-MM11 system is multivolt 9-32V. The actuator box is mounted within the engine room and 2x morse cables are connected between the actuator box and the engine throttle and gearbox actuator. The 4500-MM11 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.

Extremely easy to install and calibrate. Flexball Electronic Throttle Controls can easily be retro fitted to any existing marine engine.

The 4500-MM11 kit includes everything you need electrically. The only component not included are the 2x morse cables which connect between actuator box to throttle and actuator box to gearbox. We always highly recommend these be made locally to custom length.
