If your dash looks like this, then this mount will fit.
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.
