CORE COOLING SYSTEM INTEGRITY AND OUTBOARD ENGINE SAFETY: Restore the vital raw water circulating mechanism of your high-performance powerhead with this precision-molded impeller. Engineered to restore coolant head pressure and resolve weak telltale streams, this component is critical for preventing thermal engine deformation during momentary dry runs and high-RPM operation. By providing consistent water volume, this marine-grade part mitigates catastrophic "spun hub" failures and helps clear overheating component alarms caused by abrasive debris ingestion in harsh saltwater environments.TECHNICAL PARAMETERS AND HARDWARE SPECIFICATIONS:Outer Diameter: [ 3.54 in ] precision engineered for high-volume head pressureHub Shaft Insert Diameter: [ 0.89 in ] for zero-tolerance drive shaft fitmentImpeller Axial Height: [ 1.42 in ] ensuring proper water pump housing compressionBlade Configuration: [ 6 Blade ] design optimized for maximum lift and circulation velocityStructural Integrity: High-strength [ Vulcanized Brass Hub ] designed to resist high-torque shear stressComponent Material: Corrosion resistant marine-grade elastomer for prolonged elasticity memoryEXHAUSTIVE OE CROSS-REFERENCE AND AFTERMARKET INTERCEPTION:Replacement for Yamaha: 6CE-44352-00-00 ; 6CE-44352-01 ; 6CE-44352-00 ; 6CE-44352-03Replaces for Sierra Marine: 18-45617Replaces for GLM Marine: 89300Replaces for Mallory Marine: 9-45617Replaces for CEF Aftermarket: 500401Replaces for OBR Red Rhino: YA-112Associated Component Kits: Designed for use in complete water pump repair kits 6CE-W0078-01-00 and 6CE-W0078-02-00Related Hardware: Interfaces with Woodruff Key 90280-04002-00for Yamaha 2010 to 2025 Four-Stroke 4.2 L Precision Compatibility Matrix:225 HP F225 Models: Trims: XCA, NCA, XB, NCB250 HP F250 Models: Trims: XCA, UCA, NCA, XB, XCB300 HP F300 Models: Trims: XCA, UCA, NCA, XA, XC, NSBEXPERT DIY MAINTENANCE TIP AND INSTALLATION GUIDE: To maintain peak engine performance and prevent cooling failure, replace this marine impeller every 100 to 300 hours of operation or every 1 to 2 seasons. Always inspect the stainless-steel wear plate for scoring or pitting and lubricate the housing with marine-grade grease prior to installation to prevent dry-start tearing. Professional installation is recommended to ensure proper head pressure and long-term cooling system integrity.
