Keep your OMC outboard running cool and reliable with the Sierra 18-3202 Water Pump Kit, a trusted aftermarket solution designed for seamless performance on the water. Whether you're prepping for a weekend fishing trip or tackling longer offshore adventures, this kit ensures optimal cooling to prevent overheating and extend engine life. Boat enthusiasts know that a failing water pump can sideline your vessel fast—don't let that happen.

Precision Engineering for OMC Engines

Crafted with high-quality materials, the Sierra 18-3202 mirrors OEM specifications while delivering enhanced durability. The nitrile rubber impeller resists wear from sand, salt, and debris, common culprits in marine environments. Its neoprene housing provides superior flexibility and heat resistance, maintaining peak efficiency even under demanding conditions. This isn't just a replacement; it's an upgrade that boaters rely on for consistent water flow and pressure.

Complete Kit for Easy Rebuilds

• High-performance impeller for maximum water pickup
• Durable wear plate to protect against abrasion
• Stainless steel fasteners for corrosion resistance
• Gaskets and seals for leak-free assembly
• Key shaft and housing components for full rebuild capability

Everything you need arrives in one package, saving time and hassle during servicing. No more hunting for individual parts—get back on the water quicker.

Perfect Fit for Popular OMC Models

This kit fits a wide range of OMC outboards, including many Johnson and Evinrude models from the 1980s through the early 2000s. Always cross-reference with your engine's serial number for the best match, but it's a go-to for 40-150 HP inline engines. Boaters upgrading from worn factory pumps report smoother operation and quieter runs, thanks to the balanced design that minimizes vibration.

Installation Made Straightforward

DIY-friendly with basic tools: Drain the gear case, remove the old pump housing, inspect the drive shaft, and assemble the new kit using the included instructions. Pro tip: Apply marine grease to the impeller splines for smooth engagement and longevity. Most installs take under an hour, but flush the cooling system afterward to clear any old debris. Regular checks every 100 hours of use keep it performing like new.

Why Choose Sierra 18-3202 Over Others?

Unlike generic kits that fail prematurely, Sierra's rigorous testing ensures reliability in real-world saltwater and freshwater use. It supports higher RPMs without cavitation, crucial for towing skiers or powering through choppy waves. Owners praise its value, noting fewer breakdowns and lower long-term costs compared to dealer parts. Invest in peace of mind for your prized outboard.

Maintenance Tips for Longevity

To maximize lifespan:

1. Inspect annually or every season for impeller wear
2. Winterize by removing and storing dry
3. Monitor engine temp gauges closely
4. Use ethanol-free fuel to avoid gumming

Pair with a fresh gear lube change for comprehensive lower unit care. This proactive approach keeps your OMC humming season after season.
