If your Dash looks like this one, this mount plate will fit.
This mount fits the Ranger 522D.
If you have smaller units that are not listed in the drop-down menu for GPS/Sonar, then go to 522D Boat Dual Mounts
Note: If your Boat does not have tilt wheel, then you will need a 1-1/2″ steering spacer. These are available in the Other section.
Disclaimer: The Apex Factory Gimbal brackets have a Hole Pattern in them that “Does Not” match any previous hole pattern used by Humminbird in the past. We will send a Hole pattern with mounts that have a Apex model graph and you will need to mark your factory Apex gimbal Bracket and drill 9/32 holes them to match our pattern.
Note: The BBT Cheyenne Series Apex Gimbal Brackets will have the same hole pattern in them as Helix and Solix Gimbal Brackets.
