RPB-K Installation Guide

The following is a description of the installation procedures associated with the RPB Type-K rudder seal. Installation instructions are included with each unit and should be followed closely.

  1. Inspect that area of the rudder stock where the lip seal will rest and confirm that there is clean, smooth stock available to accept the lip seal.
  2. Block the rudder into position and disconnect the steering arm and rudder collar.
  3. Remove the blocking and carefully lower the rudder so that the rudder stock is beneath the upper rudder bearing. Confirm that there is sufficient clearance between the end of the stock and the underside of the shelf to add the Type-K unit.
  4. Remove the nuts from the threaded posts and the rudder port collar. Remove the flax packing.
  5. Inspect the upper end of the rudder stock. Remove any burrs, nicks or sharp edges which might damage the lip seal during installation or operation.
  6. Insert the red installation hat all the way into the Type-K until it covers the thin sealing edge of the lip seal.
  7. Run a bead of marine sealant (such as Lifecaulk™ or 3-M™ 101) on the underside of the flange of the unit for a watertight seal. Slide the Type-K onto the rudder stock, carefully guiding it through the red installation hat.
  8. Slide the Type-K down the rudder stock and over the threaded studs.
  9. Replace the mounting nuts (and washers) on the threaded studs. Snug.
  10. Jack the rudder back into position until the rudder stock passes through the upper rudder bearing. Block in place.
  11. Tighten the mounting nuts.
  12. Reconnect the steering arm and rudder collar.

Note: Before installing the rudder, insert the red installation hat into the lip seal. When rudder is in place, remove, invert and replace it on top of the Type-K unit to keep debris off the lip seal during use.
