Quicksilver Power Trim & Steering Hydraulic Fluid 32 oz — Marine-grade, Anti-Foam Corrosion-Resistant

Quicksilver 858075Q01 Power Trim and Steering Fluid is a 32-ounce marine hydraulic fluid formulated to protect and lubricate power trim and hydraulic steering systems (excluding electric power steering).

This Quicksilver hydraulic fluid delivers reliable performance for outboards and sterndrives by reducing foaming, shielding seals and hoses, and resisting oxidation and corrosion. It is engineered to be compatible with most hydraulic fluids used in trim and steering circuits, making it a convenient maintenance fluid to keep onboard for seasonal servicing or emergency top-ups. Always verify your owner's manual for any system-specific fluid requirements before use.

How will this fluid help my boat’s power trim and steering perform?

The Quicksilver power trim and steering fluid maintains smooth, predictable hydraulic action so trim and helm respond accurately. By minimizing foaming and corrosion, it reduces erratic movement and component wear, helping hydraulic pumps and rams run more quietly and last longer. Regular use helps preserve system integrity and prevents premature seal or hose failure.

• Minimizes foaming for consistent hydraulic pressure
• Protects seals and hoses from premature degradation
• Limits oxidation and corrosion to extend component life

Can I mix this fluid with what’s already in my system?

Quicksilver 858075Q01 is designed to be broadly compatible and can be mixed with most conventional hydraulic fluids used in trim and steering systems. However, it is not intended for electric power steering systems that specify synthetic-only fluids or for non-power hydraulic helms that require a different hydraulic fluid type. When in doubt, consult the engine or vessel manufacturer’s specifications to ensure compatibility.

• Formulated to mix with many standard hydraulic fluids
• Not for systems requiring synthetic-only fluids
• Check owner’s manual for system-specific fluid recommendations

How often should I service my hydraulic trim and steering with this fluid?

Routine inspection and periodic fluid replacement protect hydraulic components and performance. Follow your engine or boat manufacturer’s maintenance schedule—many owners inspect fluid levels and condition seasonally and replace fluid every one to two years depending on usage and exposure. Replace fluid sooner if you notice foaming, discoloration, leaks, or degraded steering responsiveness.

• Inspect fluid condition and level at least seasonally
• Replace per manufacturer schedule or when contamination appears
• Monitor for foaming, leaks, or unusual steering behavior

What are the practical benefits of choosing Quicksilver brand fluid?

Quicksilver is a long-established marine brand trusted by OEMs and boaters for parts and lubricants, so this fluid is backed by decades of marine-focused formulation and testing. Using a brand recognized by Mercury Marine and other manufacturers gives confidence that the product was developed for harsh marine conditions and offers predictable protection. It’s an easy way to maintain performance and peace of mind while preserving warranty-compliance where OEM fluids are recommended.

• Developed specifically for marine environments and hardware
• Trusted by OEMs like Mercury Marine for quality and compatibility
• Tested to resist corrosion, oxidation, and foaming under marine use

Who is this for? Boaters, marine technicians, and fleet operators who maintain outboards or sterndrives and need a dependable hydraulic fluid for power trim and conventional hydraulic steering systems will find Quicksilver 858075Q01 practical and effective. It’s suited for routine maintenance, topping off systems between services, and as an OEM-compatible option for owners who want a proven, marine-grade product. Not suitable for electric power steering systems that require synthetic fluids or specialized non-power hydraulic helms—always confirm your system’s fluid requirements before using.
