Produktbeschreibung

【Universal Compatibility】This water pump repair kit fits 2-stroke 18HP outboard motors from , , and Johnson, directly replacing OEM parts 350-65016-0 and 334-65021-0. Engineered for precise alignment with engine cooling systems, it restores water rates to 12-15 L/min at 5,500 RPM. Critical for maintaining optimal operating temperatures in high-thrust applications like waterskiing or heavy-load towing. for commercial charter boats or recreational users needing c 【Premium Construction】The 316 stainless steel housing resists saltwater , while the neoprene impeller with nylon backbone withstands temperatures from -20°C to 100°C. Lab tests confirm 1,000 hours of continuous operation without blade deformation – 3x longer than standard rubber impellers. The investment-cast housing features smooth internal contours to prevent cavitation erosion, extending pump lifespan in muddy river conditions. 【Cooling Efficiency】Rebuilds water circulation efficiency to 95% of new pump performance. The precision-machined impeller vanes maintain 0.8mm clearance with housing walls, reducing friction losses by 25% compared to worn components. Users report 15% lower engine operating temperatures during summer use, preventing overheating shutdowns in tropical climates. 【OEM Quality Assurance】Meets or exceeds SAE J1928 standards for marine impellers. Each kit undergoes 3-stage pressure testing (0-80 PSI) to prevent housing leaks. Includes serialized etching for traceability and installation documentation with torque specifications (10 ft-lbs housing bolts, 6 ft-lbs impeller nut). Backed by 2-year against material defects. 【Complete Repair Solution】Kit includes pre-coated stainless steel housing, neoprene impeller, wear plate, gaskets, and mounting hardware. The modular design allows gasket- assembly using thread sealant. Compatible with OEM thermostats and water temperature sensors. Ideal for marinas offering pump rebuild services or boat owners performing annual maintenance. Each package includes installation guide with decarbonizing instructions for optimal performance.
