KoopNautic FAL 125 Fin Stabilizer Control Unit, P/N 601.00.04 is an OEM electronic control component for a KoopNautic hydraulic fin-stabilization system. It receives vessel-motion and system feedback signals, calculates the required fin correction, and commands the hydraulic control valves so the port and starboard fins counteract vessel roll while underway.

We recently acquired a large inventory of items, these items are used, and may have minor cosmetic blemishes from previous storage (See Photos).

Please Take Note ; This unit requires physical hardware configuration using internal DIP switches and analog adjustments during installation or replacement. Proper configuration is necessary for correct operation.

We are unable to conduct a full bench test to verify its complete functionality. Therefore, we offer the buyer a 30-day period to thoroughly test the item. If it does not function properly during this time, they can return it for a full refund.
