Choosing the Right Hydraulic Steering Fluid

Use only OEM-approved hydraulic fluid for your steering system. Mixing different fluid types can cause seal damage or inconsistent steering response. Most modern systems like SeaStar and Uflex require non-silicone, anti-foaming hydraulic oils designed for marine use.

Check the fluid reservoir regularly for low levels or milky appearance — a sign of water intrusion. Bleed your system annually or after replacing hoses or fittings to remove air bubbles.

Reminder

Never substitute ATF or automotive power steering fluid in a marine system. Use only marine hydraulic steering fluid that meets OEM specifications. For smooth performance, flush and refill the system every 2 years or after any major component service.

Frequently Asked Questions

Can I use ATF in my boat’s hydraulic steering system?
No. ATF contains detergents and friction modifiers that can damage seals and affect steering response. Always use marine-grade hydraulic fluid.
How often should I change hydraulic steering fluid?
Inspect annually and replace every 2 years, or sooner if fluid appears milky, cloudy, or contaminated.
What fluid should I use for SeaStar or BayStar systems?
Use OEM-approved SeaStar/BayStar hydraulic fluid or equivalent ISO 15-grade marine steering oil. Do not mix brands.
How do I bleed my hydraulic steering system?
Attach a filler kit to the helm reservoir, open the bleeder valves at the cylinder, and pump fluid until no air bubbles appear. Tighten fittings and top off as needed.
