Sierra 18-2774 2774 Volvo S-Hose Kit Product Description
Keeping your Volvo Penta sterndrive running smoothly means staying ahead of wear and tear on critical components like the S-Hose. This vital hose assembly handles cooling water circulation and exhaust management, ensuring your engine stays at optimal temperatures during long days on the water. When cracks, brittleness, or leaks develop from age, UV exposure, or constant flexing, it's time for a reliable upgrade. Built to match original specifications, this kit restores factory performance while standing up to harsh marine environments.
Boat owners and mechanics trust it for its straightforward fit and long-lasting construction. Whether you're prepping for the season or troubleshooting overheating issues, swapping in a fresh S-Hose prevents costly downtime and protects your investment.
Key Features and Performance Advantages
- Durable, Marine-Grade Materials: Constructed from high-strength rubber compounds resistant to ozone, oil, and saltwater corrosion, ensuring years of reliable service even in demanding saltwater conditions.
- Precision-Molded Design: Exact replication of OEM shapes and dimensions for a seamless fit without modifications, reducing installation time and potential leaks.
- Complete Kit Contents: Includes the main S-Hose, necessary elbows, adapters, and stainless steel hose clamps for a full replacement job right out of the box.
- Enhanced Flexibility: Maintains pliability across a wide temperature range, from icy winters to scorching summer runs, to handle engine vibrations and drive movements.
- Leak-Proof Connections: Tapered barbs and heavy-duty clamps create secure seals under pressure, minimizing the risk of water intrusion into the exhaust system.
Why It Outperforms Standard Hoses
Unlike generic aftermarket hoses that may harden prematurely or mismatch your sterndrive's layout, this assembly uses reinforced walls to resist collapsing under vacuum or bursting from heat buildup. Real-world testing in choppy bays and high-hour applications shows it lasts 2-3 times longer than worn stock parts, saving you from repeated teardowns.
Step-by-Step Installation Tips for DIY Success
Replacing the S-Hose is a weekend warrior project that most boaters can tackle with basic tools. Always work in a well-ventilated area, engine cool, and battery disconnected for safety.
- Prep the Area: Drain cooling water by removing the petcock or loosening hoses. Tilt the drive up for better access and protect surrounding belts and wires with towels.
- Remove Old Hose: Loosen clamps with a flathead screwdriver or clamp tool. Gently twist and pull the hose free—apply penetrating oil if it's seized from corrosion.
- Clean Mating Surfaces: Wipe barbs and fittings with a wire brush and marine cleaner to remove buildup, ensuring a smooth seal.
- Install New Kit: Slide clamps onto the hose ends loosely, push onto fittings until fully seated, then position and tighten clamps 1/4 inch from the hose ends for optimal grip.
- Test Thoroughly: Refill with fresh water or antifreeze mix, run the engine at idle, check for leaks, then rev up to confirm no drips or unusual noises.
Pro Tip: Common Pitfall to Avoid
Overtightening clamps can crush the hose—aim for snug, not vise-like. Also, route the hose away from sharp edges or hot exhaust parts to extend its life.
Ongoing Maintenance and Troubleshooting
Regular checks keep your S-Hose in top shape. Inspect annually or every 50 hours: Look for soft spots, white powdery residue (delamination), or shiny cracks. Squeeze test sections for firmness—brittle hoses signal immediate replacement.
Warning Signs of Failure
- Engine overheating without obvious blockages.
- Water spraying from the drive bellows area.
- Steam or milky oil in the exhaust (water mixing).
- Unusual drive vibration from imbalance.
Pair this replacement with fresh gear lube and bellows inspection for comprehensive drive health. In cold climates, use propylene glycol antifreeze to prevent freeze damage during storage.
Perfect Fit for Common Volvo Penta Setups
Engineered for popular single and duo-prop sterndrives from the AQ and SX series, it slots right into configurations prone to hose wear. Mechanics note it's a direct swap for setups with inboard exhaust routing, restoring water flow efficiency without adapters.

Frequently Asked Questions
What does the S-Hose do in a Volvo Penta sterndrive?
The S-Hose routes cooling water from the pump through the exhaust manifold and into the drive, mixing it with exhaust gases to cool them and prevent overheating. It also helps vent water efficiently.
How do I know if my S-Hose needs replacing?
Check for cracks, bulges, leaks, or hardening. Symptoms include engine temp spikes, water puddles under the boat, or exhaust steam.
Is this kit compatible with duo-prop drives?
Yes, it fits many SX duo-prop models with matching hose routing. Confirm your engine's hose path matches the standard S-shape.
Can I install this myself without special tools?
Absolutely—basic screwdrivers, pliers, and hose clamps tool suffice. Block the trailer wheels and use jack stands for safety.
How does this compare to OEM hoses?
It uses equivalent materials and tolerances for identical performance, often at better value, with proven durability in marine testing.
What maintenance extends the life of the new S-Hose?
Flush after saltwater use, inspect seasonally, avoid dry running the engine, and store with antifreeze in cold weather.
Will this fix exhaust popping or backfiring?
If caused by poor water flow from a faulty hose, yes. Rule out ignition timing or carb issues first.
