MPower 18 ft Runabout


The MSRP price includes all NMEA 2000 wiring and connectors.

This system example is based on an MPower system designed for an 18ft Runabout.

Powering all your needs, the CLMD12 replaces the need for a traditional Main Breaker Panel handling your over-current protection and digital switching logic. Located in the helm area, the robust and waterproof MPower CKM12 provides a single point of control for quick access and control to all circuits. Use MPower to reduce weight and complexity in your vessel’s electrical system. Add a compatible MFD to have digital switching on a touchscreen or expand the system anytime with ease via NMEA 2000 networking.

The following table shows the necessary products for this system and what product features are being utilized for each product as it pertains to this system.
