Sierra Water Pump Repair Kit Without Housing for Yamaha Outboards

The Sierra water pump repair kit without housing is a replacement service kit for the raw water cooling pump on Yamaha outboard engines. The water pump (also called an impeller kit or cooling pump kit) circulates water through the engine to prevent overheating. Replacing worn parts on schedule helps keep the cooling system working properly.

Key Features:

• Replacement kit for servicing the outboard water pump without replacing the pump housing
• Built to meet or exceed OEM form, fit and function
• Includes the impeller and related service components for a complete pump rebuild
• Helps restore cooling flow and protect the engine from heat damage
• Backed by Sierra International, a long-time supplier of marine replacement parts

Sierra designs its marine parts as aftermarket alternatives to OEM components. Routine water pump service is a common maintenance item that helps extend engine life and reliability. Choose the individual item that matches your engine application.
