Impeller for Johnson/Evinrude V4 & V6 Outboards (85–300 HP)

Keep your powerful Johnson/Evinrude V4 or V6 outboard running at peak performance with this heavy-duty water pump impeller. Designed for high-displacement engines, it fits a wide range of 4-cylinder (V4) and 6-cylinder (V6) models – including classic 85–140 HP V4s and larger 150–225+ HP V6 outboards. This impeller meets the demands of these engines by moving a large volume of cooling water, which is especially critical when running at full throttle or on long runs in hot conditions.

The impeller is manufactured to OEM standards and corresponds to original OMC part numbers like 395864 and 5001593, used in many Evinrude/Johnson SeaDrive and large outboards. It includes both the drive key and a new O-ring, which help ensure a proper seal in the pump housing after installation. Replacing the impeller is key maintenance for these big engines – doing so will help avoid overheating that could lead to costly damage (such as scored cylinders or piston failure). Invest in this replacement impeller to maintain reliable cooling for your high-powered outboard.

• Broad Engine Coverage: Designed for OMC V4 & V6 outboards ranging roughly from the late 1970s through the 2000s. It covers engines used in bass boats, offshore fishing rigs, and powerboats that rely on strong cooling systems.
• Heavy-Duty Performance: With sturdy, high-quality rubber vanes, this impeller handles the stress of high RPM and extended operation. It’s ideal for big engines that generate more heat and require robust water flow.
• Complete Replacement Parts: Package includes the impeller, installation key, and O-ring seal. This ensures you have all necessary components to perform a thorough water pump service and secure the new impeller in place.
• Prevents Engine Damage: An efficient impeller is vital for large outboards to avoid overheating, especially during harsh conditions like towing skiers or running in warm shallow waters. This part helps maintain safe engine temperatures and consistent performance.
• OEM Equivalent: Matches or exceeds the original Johnson/Evinrude specifications for V4/V6 impellers. It directly replaces factory parts, making it a trusted solution for marine mechanics and DIY boaters maintaining their engines.v
