Sierra 18-6753 Hydraulic Trim Pump Assembly w/Stainless Bracket Product Description
Key Features of the Sierra Hydraulic Trim Pump Assembly
Upgrade your boat's power trim and tilt system with this robust hydraulic trim pump assembly, complete with a corrosion-resistant stainless steel bracket. Designed for seamless performance on the water, it delivers reliable hydraulic pressure to effortlessly raise and lower your outdrive, ensuring smooth operation during every outing.
- Direct Replacement Design: Engineered to match original specifications for plug-and-play installation, minimizing downtime on your vessel.
- Stainless Steel Bracket: Built to withstand harsh marine environments, resisting rust and salt exposure for longer-lasting durability.
- High-Quality Seals and Components: Precision-crafted internals prevent leaks and maintain consistent hydraulic flow, even under heavy loads.
- Compact and Lightweight: Optimizes engine compartment space without sacrificing power output.
Perfect Fit for Mercruiser Applications
This assembly fits 1983 and later Mercruiser stern drive models equipped with standard hydraulic trim systems—specifically those without quick-connect fittings. It's a go-to choice for owners of popular Alpha One, Bravo, and similar setups, restoring factory-like responsiveness to your trim controls.
Before installing, verify your system's hydraulic line types and bracket mounting points. Common mismatches occur with later quick-connect models, so double-check your outdrive serial number against standard Mercruiser charts for confidence.
Why Boat Owners Trust This Trim Pump for Superior Performance
A failing trim pump often leads to sluggish outdrive movement, unusual noises, or complete system lockup—issues that strand you dockside. This Sierra unit addresses these head-on by providing:
- Quicker Response Times: Stronger hydraulic pressure means faster trim adjustments, ideal for choppy waters or quick maneuvers.
- Reduced Maintenance Headaches: Fewer leaks and better fluid retention extend service intervals, saving you time and effort.
- Enhanced Safety: Reliable tilt-up capability during trailering or beaching prevents accidents and damage.
- Cost-Effective Reliability: Delivers OEM-level performance at a fraction of dealer prices, without compromising quality.
Marine enthusiasts report smoother operation post-install, with many noting it outperforms worn factory units after years of saltwater abuse.
DIY Installation Tips for a Hassle-Free Swap
Replacing your hydraulic trim pump is a straightforward weekend project for handy boaters. Here's a step-by-step overview:
- Prep the Area: Disconnect the battery, relieve system pressure by cycling the trim, and drain hydraulic fluid into a catch pan.
- Remove Old Pump: Unbolt the bracket, disconnect hoses (label them!), and detach electrical connections carefully.
- Install New Assembly: Mount the stainless bracket securely, reconnect hoses with new seals if needed, and wire per diagram.
- Refill and Bleed: Top off with compatible ATF or hydraulic fluid, then bleed air by cycling the trim slowly with the engine off.
- Test Thoroughly: Run full cycles on water or a test stand to check for leaks and smooth action.
Pro Tip: Always inspect hoses and rams for wear during replacement—proactive fixes prevent future failures.
Long-Term Maintenance to Maximize Lifespan
To keep your trim system humming season after season:
- Check fluid levels monthly and top off as needed—low fluid causes overheating and seal damage.
- Inspect for leaks around fittings after every 50 hours of use.
- Flush the system annually with a marine hydraulic flush to remove contaminants.
- Store with the outdrive trimmed down to equalize pressure.
Neglecting these steps shortens pump life; diligent care can double its service interval.
Frequently Asked Questions
What Mercruiser models is this hydraulic trim pump compatible with?
It fits 1983 and later Mercruiser stern drives without quick-connect fittings, including many Alpha and Bravo generations. Confirm by checking your hydraulic lines.
Does the stainless bracket make a difference in marine use?
Absolutely—stainless steel resists corrosion from saltwater and moisture far better than standard brackets, extending the assembly's life in harsh conditions.
How do I know if my trim pump needs replacement?
Signs include slow or jerky trim movement, whining noises, fluid leaks, or inability to hold position. Test by listening for pump strain during operation.
What fluid should I use with this pump assembly?
Use SAE 10W-30 or 10W-40 ATF, or a marine-grade hydraulic fluid specified for Mercruiser systems. Avoid mixing types to prevent seal damage.
Is professional installation required?
No, it's DIY-friendly for those with basic tools and mechanical knowledge. Follow a bleed procedure to avoid air locks.
Can this pump handle high-horsepower outboards?
Yes, it's rated for standard Mercruiser applications up to common V8 sizes, providing ample pressure for heavy outdrives.
What if my system has quick-connect fittings?
This model is for non-quick-connect setups only. Quick-connect systems require a different assembly to match the fittings.
