Sierra 18-3023 Neoprene Impeller, 6 Fins, Replaces Suzuki 17461-94500, for Suzuki Outboard Motors

The Sierra 18-3023 is a neoprene water pump impeller built for Suzuki outboard motors. The impeller drives raw water through the outboard's cooling system, keeping the engine running at proper operating temperature. It is molded from neoprene rubber, a material chosen for its resistance to heat, wear, and the abrasive effects of sand and grit that can pass through a raw-water intake. The impeller features 6 fins (blades) that seal against the pump housing to move water efficiently at both idle and wide-open throttle.

This impeller is finished in white and is built to meet or exceed original equipment quality, making it a direct functional replacement for the OEM Suzuki impeller in this water pump. It is designed for a specific fit, so buyers should confirm their outboard's part number against the cross-reference list below before ordering. Replacing a worn or cracked impeller on schedule helps prevent overheating damage to the powerhead, and this part is sized and finned to match the original Suzuki water pump kit it replaces.
