I just got a Z 21. It came with a Minn Kota 440 PC charger which is fairly small. I have a 460 PC charger which I want to install on the boat. The 440 is mounted on the sidewall of the battery compartment behind the passenger seat. The footprint of the area where the 440 is mounted is too small for the 460. Does anyone have a Z-21 with a 460 charger? Can you post pictures of where it is mounted?
