Impeller Johnson/Evinrude V4/V6 (85-235 HP) – Durable Cooling for Mid/Large Outboards

This impeller is tailored for the powerful Johnson/Evinrude V4 and V6 outboards, roughly covering the 85–235 HP range. As a critical part of the cooling system, the impeller ensures that these larger multi-cylinder engines (V4/V6) receive ample water flow for cooling even under heavy loads. It is made from a high-strength neoprene/rubber material capable of withstanding the extreme conditions of marine use and the high RPM operation of such engines.

The Johnson/Evinrude V4/V6 impeller is engineered to OEM specifications, providing an ideal fit in the water pump housing. The included nylon bushing insert ensures proper alignment on the drive shaft and reduces wear. With regular maintenance (manufacturers typically recommend periodic impeller replacement – usually annually or after a certain number of hours), this component will keep your engine running cool and prevent overheating. This is especially crucial for older Johnson/Evinrude V4/V6 models and OMC Sea Drive units that rely on an efficient water pump for long-lasting, reliable performance.

• High Cooling Capacity: Ideal for medium to large boats (17–25 feet) powered by Johnson/Evinrude V4/V6 engines, where robust cooling is required for long cruises or towing activities
• Compatibility: Replaces OEM impellers in numerous V4/V6 2-stroke models from the 1970s, 80s, and 90s (including OceanPro series, Sea Drive units, etc.), restoring factory pump performance
• Overheat Protection: Maintaining strong water flow is critical – this impeller helps avoid dangerously high cylinder temperatures during high RPM operation or hot weather running
• Replacement Guidelines: Inspect and replace the impeller annually or every 100–150 hours on these large engines. Keeping a spare impeller on board is recommended for extended voyages
• Quality & Reliability: The Cef Marine V4/V6 impeller is a trusted choice by marine technicians – it’s rugged, deformation-resistant, and will help keep your valuable engine in top condition
