If your dash looks like this, then this mount will fit.
TRITON TXP Models - Triton changed the steering wheel to a 1 piece Steering Wheel/ Cog. If yours boat has Hydraulic Steering, then your steering wheel should measure from the dash to the inside top edge of steering wheel, it should read about 6 3/8 - 6 5/8", If that is the case, then no spacer should be needed in most cases. If it is 4" on that measurement, then you will need a complete changeover kit to be able to add a spacer to increase area between steering wheel and unit. Pictures here shows the Steering Wheel Kit Installed
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.
