Sierra 18-3602 Product Description
Keep Your Outboard Running Cool with Reliable Water Flow
Nothing disrupts a day on the water like an overheating engine. The water intake hose plays a critical role in your outboard's cooling system, drawing in fresh water to prevent dangerous temperature spikes. This durable replacement ensures consistent performance, whether you're cruising lakes or battling ocean swells. Measuring a precise 13 7/8 inches, it fits snugly into popular setups, restoring optimal circulation without the guesswork.
Boat enthusiasts know that even small components like this can make or break reliability. Skipping subpar generics often leads to leaks or restrictions, but investing in quality pays off in smoother runs and fewer breakdowns.
Engineered for Marine Demands
Robust Construction That Lasts
- Reinforced Design: Built to withstand constant pressure, vibration, and exposure to saltwater, resisting cracking or collapsing over time.
- Precise Dimensions: At 13 7/8 inches long, it matches original specs for seamless integration, avoiding airflow disruptions.
- Flexible Yet Tough: Maintains shape under engine heat while bending to fit tight engine compartments.
- Corrosion-Resistant Materials: Handles harsh marine environments, from chlorinated lake water to salty bays.
Why It Outperforms Standard Hoses
Unlike thin-walled alternatives that balloon or burst, this hose delivers unrestricted water flow. Boaters report cooler engine temps and quieter operation after swaps, especially on older motors showing wear. It's a straightforward upgrade that boosts confidence during long hauls.
Perfect Fit for Common Outboard Applications
This hose slots into a range of mid-range outboards from leading brands, ideal for powerheads needing reliable cooling paths. Check your engine's service manual for exact matches, but it's a go-to for mechanics tackling routine refreshes. No modifications required—barb ends grip securely with standard clamps.
Step-by-Step Installation Tips
- Prep the Area: Shut off fuel and disconnect the battery. Drain any residual water from the cooling lines.
- Remove Old Hose: Loosen clamps with pliers or a screwdriver. Twist gently to break seal—avoid forcing to prevent barb damage.
- Inspect Connections: Clean barbs and check for corrosion. Replace O-rings or gaskets if worn.
- Install New Hose: Slide over barbs, ensuring full coverage. Position for minimal kinks—route away from hot exhaust paths.
- Secure and Test: Tighten clamps evenly (not overtight). Prime the system, run the engine on muffs, and watch for leaks.
Pro tip: Apply a light marine lubricant to barbs for easier installation, but wipe excess to avoid slippage. Most swaps take under 30 minutes with basic tools.
Extend Life with Simple Upkeep
Regular checks keep this hose performing season after season. After every 50 hours or saltwater trip, inspect for softening, cracks, or debris buildup. Flush the cooling system with fresh water post-use to minimize mineral deposits. During winterization, disconnect and store dry to dodge freeze damage.
"Swapped this in after noticing sluggish cooling—engine runs like new, no more steam on hot days." – Experienced angler
Pair it with a full cooling system refresh for peak efficiency, catching issues early.
The Edge of Trusted Marine Parts
Backed by decades in the industry, Sierra components mirror OEM quality at a fraction of the hassle. They're rigorously tested for marine extremes, giving peace of mind when you're miles from shore. Boaters choose them for consistency—fewer returns, more time on the water. Whether DIY or pro install, it's engineered to exceed expectations.
