585 MicroCommander
The 580 Mathers MicroCommander actuator was the fifth version of the MMC MicroCommander. This actuator controls one engine/gear with mechanical throttle and mechanical shift.

The 585 often had auxiliary boards to provide engine synchronization, and sometimes interfaced to the 813 or 813CE Troll actuator.

The replacement most often required for the Mathers 585 is the 91100 ClearCommand, however the 91102/3/4/5 can also be used.

We can assist you with selecting the best ZF 9000 series Micro Commander for  replacing your old 585 at affordable prices.

You can also use the existing wiring on your boat. You DO NOT need to change the entire system, just the processors and possibly a couple wires in the engine room; all control heads work with the new 9000 series ClearCommands!
I was the Service Manager at Mathers Controls Inc and at ZF Mathers, so know these systems thoroughly, and can provide tech support from system purchase, to dock trials and sea trials.
