Sierra 18-2435 Product Description
Upgrade Your Boat's Power Trim System with Reliable Hydraulic Performance
Nothing disrupts a day on the water like a faulty power trim hose. Leaks, pressure loss, or sluggish operation can turn your boating adventure into a hassle. The Sierra 18-2435 power trim hose steps in as a robust replacement, engineered to restore smooth, responsive control to your outboard's hydraulic trim system. Crafted from high-grade materials resistant to saltwater corrosion, oil, and extreme pressures, this hose ensures your trim and tilt functions flawlessly even after repeated exposure to harsh marine environments.
Boat owners rave about its direct-fit design, which mirrors original equipment specifications without the premium markup. Whether you're tilting up for trailering or fine-tuning your prop angle for optimal performance, this hose delivers consistent hydraulic flow to keep you on plane and fishing longer.
Perfect Fit for Popular Outboard Models
Designed as a drop-in replacement for legacy power trim components, the Sierra 18-2435 aligns seamlessly with a range of Mercury outboards from the 1980s through early 2000s. It's commonly paired with inline and V6 engines where hydraulic trim systems rely on durable hoses to connect the pump to cylinders. Check your engine's service manual for the matching OEM reference to confirm compatibility—many DIY mechanics find it bolts right up, saving hours in the shop.
- Supports high-pressure hydraulic circuits up to demanding marine specs
- Flexible yet durable construction handles tight bends in engine compartments
- Resists abrasion from rigging and vibration during high-speed runs
Key Features That Stand Out in Real-World Use
What sets this power trim hose apart isn't just its specs—it's how it performs under pressure. Built with reinforced rubber layers and brass fittings, it withstands bursts up to 1,500 PSI, far exceeding casual weekend use. The nitrile inner tube shrugs off hydraulic fluid degradation, while the braided polyester cover fights off UV rays and chafe from cowling movement.
Owners report fewer air intrusions and leaks post-install, leading to quieter operation and better fuel efficiency from precise trim adjustments. It's not just a part; it's peace of mind for anyone who trailers their rig frequently or pushes their boat in rough chop.

Step-by-Step Installation for DIY Boat Mechanics
Replacing a power trim hose doesn't require a marine yard lift. With basic tools—a wrench set, flare nut wrench, and hydraulic fluid—you can swap it out in under an hour. Start by powering down and relieving system pressure: cycle the trim a few times with the key off.
- Disconnect battery and battery switch for safety.
- Loosen fittings at the trim pump and cylinder—use penetrating oil if seized.
- Remove old hose, noting routing to avoid kinks.
- Install new Sierra 18-2435, hand-tighten then torque to spec (typically 15-20 ft-lbs).
- Top off fluid, bleed air by cycling trim slowly, and test under load.
Pro tip: Inspect O-rings and seals during swap; worn ones amplify hose failures. A quick freshwater flush post-install extends life.
Prolonging Hose Life: Essential Maintenance Routines
Marine hydraulics thrive on prevention. Annually inspect your power trim hose for cracks, bulges, or weeping fittings—early signs of fatigue. Rinse with freshwater after saltwater runs to neutralize corrosion, and store your boat with trim tilted down to minimize stress.
Avoid over-pressurizing by not forcing tilts against stops. If you notice spongy response, it's often trapped air or fluid loss rather than hose failure. Regular checks keep downtime minimal and your adventures uninterrupted.
Why Trust Sierra for Your Engine Parts Needs
Sierra has built a reputation among boaters for precision aftermarket parts that punch above their weight. Unlike generics that balloon under heat cycles, Sierra components undergo rigorous testing to match OEM durability at a fraction of the cost. It's the choice for savvy owners who value reliability without compromising their wallet—backed by mechanics who swear by it for everything from weekend warriors to charter fleets.
