Mine is a single-output, but other than that, yes - the same one. The mount is nice to have - makes it so easy. I would recommend testing the plug in the mount before you install it. Mine had a little play in it, so I used a tie-wrap around it to hold the tab down on the mount.
I picked a spot that I could reach without getting on the boat to plug it in. I also wanted to make sure I could access the back side of the hole to tighten the nut install the tie-wrap. You will notice the cup holder right below the mount. I removed the cup holder and could reach up to do everything pretty easily. That way I didn't have to stand on my head to access it from the engine compartment. Used a hole saw to drill the hole, w/ masking tape covering about 4x the hole size to protect the gel coat.
I mounted the charger in the engine compartment, using stainless steel bolts and nylock nuts. The other side of the charger is the under-seat storage compartment, so you can't even see the bolts with the carpet in the compartment.
I did have to extend the battery connections because the battery is on the starboard side, and the mount for the plug is on the port side. Not a big deal. I love the setup.
