Steering into the Season – Pre-Launch Tips for Your Hydraulic Steering and Autopilot Systems
As launching season approaches, many boats are being readied after months of storage. One system that often gets overlooked – but is absolutely critical to enjoy safe and enjoyable sailing—is you’re the hydraulic steering and autopilot setup.
Whether you’re navigating tight harbours or cruising offshore, your steering must be responsive, smooth, and reliable. Before you hit the water, here are a few essential checks and maintenance tips from Mathew Erato, Hydraulics Department Project Manager:
1. Check Hydraulic Fluid Levels
Start with the basics. Make sure your helm pump reservoir is filled to the correct level. Low fluid can introduce air into the system, leading to spongy steering or sluggish response.
Pro Tip: Always use the manufacturer-recommended hydraulic fluid. Avoid mixing fluid types. If doing a complete flush, can opt to change fluids entirely, keeping to manufacture guidelines of course!
2. Inspect the Fluid Condition
Fluid that appears milky, discoloured, or contains visible particles may be contaminated with water, air, or debris. This reduces performance and can damage seals and components.
How to check: Dip a clean white cloth or swab into the reservoir. Healthy fluid should be clear and uniform in colour. If it looks off, consider flushing and replacing it.
3. Inspect All Connections
Give all hose fittings, unions, and helm/pump interfaces a careful visual once-over.
Make sure that:
- Locknuts on autopilot rams are secure and torqued to spec.
- Hoses are properly pinned or secured with clamps or fittings.
- There is no visible corrosion, cracking, or swelling on hoses or fittings.
4. Check for Leaks and Seal Integrity
Look around rams, fittings, and helm pumps for any signs of oil leaks or dampness. A minor leak on land can become a major issue when system is under pressure.
What to look for:
- Oil around ram shafts (a sign of worn seals).
- Fluid drips under the helm or near the cylinder.
- Gradual drop in fluid level over time.
5. Bleed Out Any Air
Air in the system will cause “spongy” or inconsistent steering. If the wheel feels soft, noisy, or doesn’t return to centre properly, bleeding may be required.
Simple DIY method: Turn the wheel lock-to-lock several times while topping up the reservoir. For full system bleeds or recurring issues, have the system serviced by a professional.
6. Test the Autopilot Linkage
Once everything is tight and fluids are checked, engage the autopilot to verify full range of motion and smooth operation. Listen for irregular noises or hesitations—these can signal binding or worn components.
Final Thought
Steering is one of the critical systems on board. A 30-minute pre-launch check now can prevent hours of downtime—or worse—later on.
If your system has not been professionally serviced in the past few seasons, or if you are unsure about any of these checks, get in touch with our team. We will ensure you’re steering and autopilot systems are ready for a safe, smooth season on the water.
