MS541-11749 MS540-11790

The MS541-11749 & MS541-11790 are the old  Mathers ClearCommand for boats with Cummins electric throttle, and mechanical shift.
The replacement most often required for the these MS541's is the 92100 ClearCommand, however the 92102/3/4/5 can also be used, or even the 9211X or 9212X.

We can assist you with selecting the best ZF 9000 series ClearCommand for  replacing your old MS541 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.
