Sierra 18-3097 Neoprene Water Pump Impeller, Replaces Suzuki 17461-98501, for DF4/DF6, DT2-DT8 Outboards

The Sierra 18-3097 is a neoprene water pump impeller with 6 fins, built as a direct replacement for the impeller used in a range of Suzuki outboard motors. It is the wear component inside your outboard's water pump that draws in raw water to cool the engine, and it is one of the most common maintenance parts on any outboard since neoprene fins lose flexibility and cooling efficiency over time, especially if the engine is ever run dry even briefly. Replacing the impeller on the recommended service interval helps prevent overheating and the more expensive damage that can follow, such as a cracked water pump housing or a scored driveshaft.

This impeller is designed for use in Suzuki DF4/DF6, DT2, DT3.5, DT4, DT5, DT6, and DT8 outboard engines. It is sold as a single impeller, one per package, and is intended to be installed as part of a water pump service along with the associated pump housing, gasket, and wear plate. It is also referenced for use with Sierra's 18-3259, 18-3260, and 18-3266 water pump kits and repair kit when a full pump rebuild is being performed rather than an impeller-only swap. Each Sierra part is built to meet or exceed the specification of the original equipment part it replaces.

How much does the impeller weigh? The Sierra 18-3097 impeller weighs 0.03 pounds.

What material is the 18-3097 impeller made from? It is made of neoprene and has 6 fins, the standard material and fin configuration for outboard water pump impellers.

Does the 18-3097 come with the water pump housing or gasket? No, the package includes one impeller only. The pump housing, gasket, and wear plate are separate parts, and a full rebuild can be done with Sierra's 18-3259, 18-3260, or 18-3266 water pump kits.

Is the Sierra 18-3097 a genuine Suzuki part or aftermarket? The 18-3097 is a Sierra-manufactured aftermarket replacement, built to meet or exceed the original Suzuki impeller it replaces rather than being a Suzuki-branded OEM part.

How do I know if my water pump impeller needs replacing? Reduced or no water stream from the outboard's tell-tale, overheating, or a whining pump noise are common signs the impeller fins have worn down and the 18-3097 impeller needs to be installed.

Can I install the 18-3097 by itself or do I need a full kit? The 18-3097 can be installed on its own as an impeller-only replacement, or alongside Sierra's 18-3259, 18-3260, or 18-3266 water pump kits if the housing and gaskets also need replacing.

What color is the 18-3097 impeller? The Sierra 18-3097 impeller is white.

Does the same impeller fit both the DF4/DF6 and DT2 through DT8 Suzuki models? Yes, the Sierra 18-3097 is the correct impeller across the listed Suzuki DF4/DF6 and DT2, DT3.5, DT4, DT5, DT6, and DT8 models.

Is the Mallory 9-45504 the same impeller as the Sierra 18-3097? Yes, the Mallory 9-45504 is a cross-referenced equivalent to the Sierra 18-3097 impeller.
