Keep your Suzuki outboard running cool and reliable with the Sierra 18-3097 impeller, a precision-engineered replacement for the OEM Suzuki 17461-98501. Designed for boaters who demand performance without compromise, this impeller ensures optimal water flow through your engine's cooling system, preventing overheating during those long days on the water.

Perfect Fit for Suzuki Outboards

This impeller matches the exact specifications of the original Suzuki part, making it a seamless upgrade for a wide range of Suzuki models. Whether you're maintaining a compact tiller or a powerful offshore rig, the Sierra 18-3097 slots right in, restoring factory-level cooling efficiency. Boaters report smoother operation and extended engine life after swapping in this reliable aftermarket option.

Built to Withstand Harsh Marine Conditions

• Durable Neoprene Construction: Resists swelling, cracking, and degradation from ethanol-blended fuels, UV exposure, and saltwater corrosion—common killers of stock impellers.
• High-Performance Vanes: Precision-molded for maximum water pumping capacity, delivering consistent flow even at high RPMs.
• Exact OEM Dimensions: 2.17-inch outer diameter, 1.18-inch inner diameter, and 1.57-inch length ensure no modifications needed for installation.

Unlike flimsy generics, Sierra's engineering focuses on longevity, with many users logging thousands of hours before the next service interval.

Spot the Signs: When to Replace Your Impeller

Overheating warnings, steam from the tell-tale, or reduced water pressure? These are red flags from a worn impeller. Neglect it, and you risk warped heads or seized pistons—costly repairs that sideline your boat. Routine checks every 100-200 hours or annually keep you ahead of trouble. Pro tip: Always inspect during winterization to catch hidden wear from debris or dry running.

Simple DIY Replacement Tips

1. Drain the water from the lower unit and remove the pump housing cover.
2. Pull the old impeller with needle-nose pliers or a puller tool—twist while pulling to break it free.
3. Lubricate the new Sierra 18-3097 with marine grease, align the keyway, and press it onto the drive shaft.
4. Reassemble, prime the system, and test-run to confirm strong water flow.

Total time: Under 30 minutes for experienced wrenches. No special tools required beyond basics.

Why Sierra Over Other Brands?

Sierra stands out in the aftermarket marine world for rigorous testing that mirrors real-world abuse—think prolonged idling, cavitation, and temperature swings. It's not just a part; it's peace of mind, backed by a boating community that trusts it season after season. Skip the OEM markup and get equivalent (or better) quality that performs in freshwater lakes or salty bays.

Maximize Engine Longevity with Proper Care

Pair your new impeller with fresh gear lube and inspect the pump housing for scoring. Flush after every saltwater trip to rinse salt buildup. These habits extend service intervals and keep cooling performance peak. Boaters who've made the switch rave about fewer breakdowns and more time fishing or cruising.
