Keep your outboard engine running smoothly on every trip with the Sierra 18-99189 Fuel/Water Separator Gas Kit, designed as a reliable Racor-compatible solution. This kit tackles one of the biggest threats to marine engines—water contamination in fuel—by efficiently separating and trapping moisture before it reaches your motor. Boat owners know the frustration of sputtering engines mid-water due to bad gas; this rugged setup changes that, extending filter life and preventing costly repairs.

Built for Harsh Marine Conditions

Crafted with a corrosion-resistant painted aluminum bracket, this kit stands up to saltwater spray, humidity, and constant vibration without breaking a sweat. The heavy-duty construction means it delivers trouble-free performance season after season, whether you're trolling bays or pushing through rough offshore waves. Unlike flimsy alternatives, its robust design ensures a secure mount that won't loosen over time.

Smart Water Drainage for Longer Filter Life

Water in your fuel isn't just inconvenient—it's destructive, leading to corrosion, injector issues, and power loss. This separator shines by letting you easily drain collected water, preserving your filter element and saving you from frequent replacements. Regular draining becomes a quick ritual that keeps fuel flowing clean and your engine firing on all cylinders.

AquaVue Clear Bowl: Visibility You Can Trust

Perfect for outboard and above-deck use, the included AquaVue clear bowl lets you visually inspect fuel quality and water buildup at a glance. Spot problems early, drain without guesswork, and maintain peak performance. It's a game-changer for DIY mechanics who want transparency in their maintenance routine—no more blindly swapping filters.

Compliance and Safety First

For below-deck installations, swap to a flame-resistant metal bowl to meet USCG regulations. This kit gives you the flexibility to stay legal and safe, no matter where you mount it on your vessel. Prioritize protection without sacrificing functionality.

Real-World Reliability for Outboard Enthusiasts

Imagine heading out for a weekend fishing charter, confident that your fuel system's protected against ethanol-blended gas woes common in modern marinas. Sierra's engineering draws from decades of marine expertise, making this kit a go-to for Mercury, Yamaha, and other outboard owners seeking OEM-level performance at a smarter value. It's not just a part—it's peace of mind on the water.

Pro Tips for Maximum Performance

• Drain the bowl weekly or after every 50 hours of use to catch condensation early.
• Pair with high-quality fuel treatments to combat moisture from humid storage.
• Mount securely away from exhaust heat for optimal flow and longevity.
• Inspect the clear bowl during pre-launch checks—clear fuel means happy engines.
