Yep. You are covered.

The 360 will need a power source, I tapped into the power coming up front for my depth finder. I installed both the 20' ethernet cable and the short power cable to my front console and connect these to ethernet and power cable attached to the 360 each time I launch the boat. Apparently the 360 will drain your battery if you keep it connected to power.

By the way, I want to see just how brighter that screen is than my old 898.
