ECU Maxx Complete Replacement Control Kit
We made the ECU-Maxx Replacement Kit so you can continue to enjoy your DX (direct expansion) AC on your vessel. Simplicity, quality and perfection.

With the complete kit’s simple adapter plate, newly designed control board with a 15 foot 8-pin cable, and a small amount of rewiring to the attractive display, you will be chilling again in no time!

If your ECU Maxx is on the fritz, this is the replacement kit for the fouled up control board. It contains all you need to close the hatches and turn on the air conditioning again. Works in all DX (direct expansion) cabin control systems.

** Cable length is limited to 15 feet. Add a note to your order for special cable length.
