URB Low Profile Installation Guide

The following is a brief description of the installation procedure for the URB-LP. Complete installation instructions are included with each unit and should be followed closely.

  1. Block up the rudder securely.
  2. Remove steering arm/quadrant from the rudder stock.
  3. Disconnect rudder collar and remove.
  4. Remove existing rudder bearing bolts and remove rudder bearing.
  5. Fill the existing bolt holes left in the shelf from the old bearing with fiberglass and resin.
  6. Slide the URB unit onto the rudder stock and into position on the rudder shelf.
  7. Using the URB-LP unit as a template, trace the diameter of the base onto the rudder shelf so that a clearance hole may be cut.
  8. Remove the unit and, using a jigsaw, cut a clean hole through the rudder shelf.
  9. Align/rotate the unit so that new bolt holes can be drilled through the shelf. (Backing plates are available for extra strength).
  10. Drill new holes through the shelf using the holes in the flange as a template.
  11. Align the unit with the pre-drilled holes in the shelf. Insert the required number of stainless steel hex bolts (with washers and lock washers) through the assembly and secure to the rudder shelf. Large fender washers or backing plates should be used against the bottom of the rudder shelf.
  12. Reposition the rudder collar so that it contacts the bearing in the URB unit and secure. Use washers as necessary to align the rudder collar with the original set screw "dimples".
  13. Remove the blocking from the rudder and verify that the rudder swings freely.
  14. Reassemble the other steering system components (arm, quadrant, etc.).

NOTE: To be properly installed, the "barrel" portion of the URB-LP must be at least 50% supported. See diagram below for details.
