Compatible Engines

The SIERRA 118-32455 water pump impeller is a critical component of the cooling system, engineered for reliable performance in marine propulsion units. This part is specifically designed for HONDA outboard engines with 8 and 9.9 HP (from 2001) and 15 and 20 HP (from 2003). With precise dimensions of 45x14.8x16.2 mm, it ensures a perfect fit and efficient heat dissipation from the engine block.

Due to the nature of aftermarket spare part production, compatibility with other engine models should be verified by comparing the catalog number 118-32455 or the original OE number. If you have any doubts about selecting the correct part for your specific boat model, please contact our customer support team for assistance.

Installation and Maintenance

• SIERRA Original Quality – guarantees durability and wear resistance.
• Safe Operation – prevents engine overheating in harsh conditions.
• Easy Replacement – standard size facilitates servicing.
• Full Compatibility – fits specified Honda models perfectly.

Regular replacement of the impeller is an investment in your engine's longevity. We recommend checking the condition of the element before each season. If the impeller is worn, cracked, or has lost elasticity, immediate replacement with a new SIERRA 118-32455 will prevent costly breakdowns. Remember to clean the pump housing of debris before installation and use appropriate silicone grease to extend the life of the new part.
