  1. Loosen the lock nut on the piston end and detach the mounting rod.
  2. Detach the bolt from the bracket hole, adjust the engine angle, then align the bracket with the engine mounting holes and secure it using bolts and nuts.
  3. Adjust the engine angle and piston rod length. Insert the stainless steel C-clip into the proper groove based on the spacing.
  4. After installation, tighten the locking nut to avoid piston movement clearance.

4.3 Hose Connection and Bleeding

  • Connect the high-strength hydraulic hoses between the helm pump and the steering cylinder using the provided quick-fit 5/16-inch fittings and elbow fittings.
  • Ziurtatu konexio guztiak estu daudela ihesak saihesteko.
  • Sistemaren odoljarioa: Before first use, the hydraulic system must be properly bled to remove all air. This ensures optimal performance and prevents spongy steering. Refer to the detailed bleeding instructions in the separate user manual provided with the kit.

5. Funtzionamendu-argibideak

Once the system is properly installed and bled, operating your hydraulic steering system is straightforward.

  • Zuzendaritza: Turn the steering wheel clockwise to steer the boat to starboard (right) and counter-clockwise to steer to port (left). The hydraulic system provides smooth and responsive control.
  • Lock-to-Lock Turns: The system provides approximately 5 turns lock-to-lock for precise maneuvering.
  • Engine Trim/Tilt: The hydraulic steering system operates independently of the engine's trim and tilt functions. Ensure these are adjusted as needed for optimal boat performance.
  • Eragiketa aurreko egiaztapena: Before each use, visually inspect the steering system for any leaks, loose connections, or damage. Confirm the steering operates smoothly from lock to lock.

6. Mantentzea

Regular maintenance will extend the life of your hydraulic steering system and ensure safe operation.

  • Fluidoen mailaren egiaztapena: Periodically check the hydraulic fluid level in the helm pump reservoir. Top up with the recommended hydraulic fluid if necessary. The fill port is located on the top of the helm pump.
  • Ihesak ikuskatzea: Regularly inspect all hoses, fittings, and seals for any signs of hydraulic fluid leaks. Address any leaks immediately to prevent system failure.
  • Mahuka egoera: Check hydraulic hoses for cracks, chafing, or kinks. Replace damaged hoses promptly.
  • Cylinder Rod Inspection: Inspect the cylinder rod for corrosion or pitting. Keep the rod clean and free of debris.
  • Ardatz zigilua: The helm pump features a replaceable shaft seal. If leakage occurs around the steering wheel shaft, the seal may need replacement.
