Sierra 18-4526 Impellers & Parts The Sierra 18-4526 is a complete impeller kit designed specifically for Evinrude G2 outboard engines ranging from 150 to 300 horsepower. This comprehensive kit includes everything needed for a complete water pump impeller replacement, ensuring your engine's cooling system operates at peak efficiency. The impeller is the heart of your outboard's raw water cooling system, drawing water from outside the boat and circulating it through the engine to prevent overheating. Manufactured to meet or exceed OEM specifications, this Sierra impeller kit features a high-quality rubber impeller with precisely molded blades that create the pumping action necessary for proper water flow. The kit typically includes the impeller, gaskets, seals, and other components required for a complete service. Regular impeller replacement is one of the most critical maintenance tasks for outboard engines. Marine engine manufacturers typically recommend impeller replacement annually or every 100-200 hours of operation, whichever comes first. Impeller blades can become worn, cracked, or damaged from debris, dry running, or normal wear, leading to reduced water flow, overheating, and potentially catastrophic engine damage if not addressed promptly. Designed specifically for Evinrude G2 engines from 150-300 HP, this kit ensures proper fit and function for your specific engine model. The quality construction provides reliable performance and durability, giving you confidence that your engine's cooling system will function properly season after season. Regular impeller service is essential preventive maintenance that protects your investment and prevents costly repairs from overheating damage. Whether you're performing routine annual maintenance or replacing a failed impeller, this Sierra kit provides all the components needed for a professional-quality water pump service on your Evinrude G2 outboard.
