The MS540-12946 & MS540-12947 are the old Mathers ClearCommand
for boats with MAN or MTU electric throttle, and electric solenoid shift.
The replacement most often required for the these MS540's is the 92200 ClearCommand, however the 92202/3/4/5 can also be used, or even the 9221X or 9222X.
We can assist you with selecting the best ZF 9000 series ClearCommand for replacing your old MS540 at affordable prices.
USE EXISTING WIRING!
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.
