2017 + RT Models - Ranger 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. Steering Wheel Changeover Kit can be purchased here.
If you have a current sonar/gps unit mounted in the dash, please list in the box below. If there was no unit mounted in dash, please write "none".
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.
If you have smaller units that are not listed in the drop down menu for GPS/Sonar, then go to the RT178 / RT188 / RT198 - Single Mount
