Sierra 18-9701-2 97012 Power Trim & Steering Fluid, Qt.

Keep your Volvo Penta marine engine running smoothly on the water with Sierra 18-9701-2 Power Trim & Steering Fluid. This quart-sized formula is specially engineered for the hydraulic demands of power steering pumps and trim cylinders, delivering reliable performance in harsh marine environments. Boat enthusiasts trust it to maintain optimal system pressure, prevent wear, and ensure responsive control during every outing.

Why This Fluid Excels in Volvo Penta Systems

Volvo Penta hydraulic steering and power trim systems operate under extreme conditions—high pressure, saltwater exposure, and temperature swings. Standard fluids often break down quickly, leading to sluggish steering or uneven trim response. Sierra's formulation stands out by providing:

• Robust rust and corrosion protection: Shields metal components from saltwater damage, extending the life of pumps, cylinders, and rams.
• Oxidation resistance: Maintains viscosity over time, reducing fluid degradation and minimizing costly replacements.
• Low-temperature performance: Flows effortlessly in cooler waters, ensuring quick response even after overnight mooring in chilly conditions.
• Compatibility assurance: Matches the exact specifications Volvo Penta requires, preventing seal swelling or system leaks.

Unlike generic hydraulic oils, this fluid is tailored for marine outboards and sterndrives, helping you avoid the downtime and repair bills associated with incompatible products.

Essential Maintenance Tips for Peak Performance

Regular fluid changes are key to protecting your investment. Check levels before each season or after 100 hours of use—top off as needed. For a full service:

1. Run the engine to warm the system, then shut off and position the trim fully down.
2. Clean fittings and remove the vent plug to release pressure.
3. Drain old fluid completely, inspect for contamination like water or metal particles.
4. Refill slowly while cycling the trim and steering to purge air bubbles.
5. Monitor for leaks and recheck levels after a test run.

Pro tip: Pair with routine greasing of pivot points to maximize system longevity. Clean storage prevents moisture buildup, which can compromise fluid integrity.

Real-World Reliability for Boaters

From weekend cruisers to serious anglers, users report buttery-smooth steering and precise trim control that holds up trip after trip. It tackles the challenges of towing watersports gear or navigating choppy bays without hesitation. By choosing a marine-specific fluid like this, you're prioritizing safety and efficiency—critical when seconds count on the water.
