Impeller Johnson/Evinrude 25-35 HP – High Reliability Cooling for Compact Engines

The Johnson/Evinrude 25-35 HP impeller is designed to improve and maintain cooling in compact outboards ranging from 25 to 35 HP, particularly those produced from 1977 to 1986. This impeller directly replaces the original parts with reference numbers 388702 and 395289, ensuring hassle-free compatibility and restoration of the factory water pump performance. With 6 flexible blades and optimized dimensions (Inner Ø 15.95 mm, Outer Ø 51.2 mm, Height 19.05 mm), it provides a steady flow of coolant through the engine.

The impeller is manufactured using high-grade materials that resist corrosion and wear, allowing it to withstand both saltwater and freshwater conditions. A pump gasket is included in the kit, which simplifies installation and prevents leaks – ensuring proper pressure and circulation of water in the cooling system. By replacing the impeller regularly (recommended annually), your Johnson/Evinrude 25-35 HP engine will maintain optimal operating temperature even during prolonged runs or demanding conditions. This means longer engine life and a reduced risk of unexpected breakdowns on the water.

• Perfect for Boats: This impeller is ideal for small to mid-sized boats (e.g., 3–5 m in length) – fishing skiffs, tow boats for watersports, or console boats equipped with 25-35 HP Johnson/Evinrude engines
• Restored Performance: Replacing the old impeller with this unit brings back full cooling capacity to older engines, allowing them to run smoothly whether idling for trolling, cruising, or at full throttle
• Easy Installation: OEM-matched dimensions and the included new gasket make installation quick and straightforward, with no special adjustments needed
• Extended Engine Life: By keeping the engine cool, the impeller reduces thermal stress on components, translating into less wear and fewer repair costs over time
• Maintenance Tip: Always flush your engine with fresh water after saltwater use and inspect the impeller at the start of each season – timely replacement will save you from headaches on the water
