Actuator Replacement

Preparation

  1. Turn off the boat, including the engines and the Seakeeper Ride system.
  2. Cut off current shrink wrap and unclip the plastic casing protecting the Actuator wires.
  1. Unpin the current Actuator being replaced from the Ampseal plug case. Use a pick tool to gently move the plastic pieces holding the pins and pull the pins out.
  1. Loosen the Cable Gland from inside the hull to ensure the cable will be able to move freely.

Removal

  1. Remove the four (4) M8-1.25 x 20 mm Hex bolts holding the Blade in place.
  1. Remove the Seal Plate
    • Remove the six (6) M6-1.0 x 16 mm Flat Head Socket Cap Screws from the bottom edge of the Seal Plate. (Note: The Seakeeper Ride 600 system will have eight (8) screws).
    • Remove the six (6) M6-1.0 x 30mm Socket Head Cap Screws from the top face of the Seal Plate. (Note: The Seakeeper Ride 600 system will have eight (8) screws).
  1. Remove the Seal Plate and Actuator by pulling the cable out through the gland.

Rebuild

  1. Place the new Actuator in the Actuator Plate. Ensure the Actuator is in same orientation as it was mounted prior to removal.
  2. Set the Seal Plate back over the Actuator and secure it in place with two (2) M6-1.0 x 30mm Socket Head Cap Screws in wing positions. Apply Vibra-Tite 132 thread locker to the screws. Torque screws to 60 in-lbs (6.8 N-m). (Note: The Seakeeper Ride 600 system will have four (4) screws). Vibra-Tite 132 replaces the previously-specified thread locker.

Apply Torque two (2) times to ensure fasteners are seated.

  1. Secure the Seal Plate bottom with six (6) M6-1.0 x 16 mm Flat Head Socket Cap Screws from the bottom edge of the Seal Plate and apply Vibra-Tite 132 thread locker to the screws. Torque screws to 60 in-lbs (6.8 N-m). (Note: The Seakeeper Ride 600 system will have eight (8) screws). Torque of 60 in-lbs (6.8 N-m) is 20% greater than previously specified.

  1. Replace the Blade with four (4) M8-1.25 x 20 mm Hex bolts, apply Vibra-Tite 132 thread locker. Torque to 80 in-lbs (9 N-m). Apply Torque two (2) times to ensure fasteners are seated.
  2. Tighten the cable gland to ensure equipment is restored and water tight.

Reprogram

The new Actuator will need to be programmed and the Blade zeroed.

  1. Turn on the Seakeeper Ride system.
  2. From the MFD, select manual mode.
  3. Press the menu button in the top right corner of the screen and navigate to the Faults page.
  4. Find the System Disable fault, which will contain a link to programming the new Actuator. Click this link and follow on screen prompts.
  5. Follow the instructions for Controller Zeroing and Diagnostics for both port and starboard Controllers.

If the programming link is not found, perform a Factory Reset in the Service Menu to fully recommission the system.
