Mercury/Mariner 6–9.8 HP Impeller – Efficient Cooling Performance

This Mercury/Mariner 6–9.8 HP impeller is designed to maintain efficient cooling for small outboard engines. It fits popular models in this range, including classic 2-stroke Mercury/Mariner 6HP, 8HP, and 9.8HP engines. Crafted from high-quality neoprene with 6 sturdy blades, it ensures a steady flow of cooling water. This means your engine is reliably protected from overheating whether it’s idling at low revs for trolling or running at full throttle.

Thanks to precise OEM-standard dimensions, this impeller installs easily onto your water pump housing. The replacement doesn’t require specialized tools – basic hand tools suffice, and the process is quick. Regular impeller changes (typically yearly or per manufacturer guidelines) are an inexpensive way to protect your motor from costly repairs. A new impeller restores optimal cooling performance, which is especially crucial for older engine models that may run hot if not properly cooled.

Mercury/Mariner outboards from 6 to 9.8 HP often power small inflatable dinghies, rowboats equipped with auxiliary motors, or serve as kicker engines on sailboats around 5–6 meters. This impeller is perfect for such uses – it keeps your engine cool during long trolling sessions while fishing or when pushing your boat back to shore. As part of preventive maintenance, it’s wise to carry a spare impeller on extended voyages or when operating in unfamiliar waters.

The impeller replaces the original pump rotor (equivalent to Mercury OEM #47-22748) and adheres to strict quality standards. It delivers the same performance and reliability as the genuine part. With this high-reliability impeller installed, your Mercury/Mariner 6–9.8 HP engine will run optimally, giving you confidence and safety on the water.

• Optimal Cooling Effect: Keeps small engines at steady temperature, preventing overheating during prolonged operation or hot weather.
• Great for Auxiliaries: Ideal for kicker motors on sailboats or dinghies used for maneuvering and docking – ensures your auxiliary engine stays cool.
• Reliable for Fishing: Lets your outboard run at slow speeds (trolling) for extended periods while fishing without the risk of overheating.
• Easy Preventive Care: Regular impeller replacement provides long-term engine protection – an inspection and change at the start of each season is recommended.
• Certified Quality: Manufactured to standards equivalent to the original, guaranteeing full compatibility and high efficiency.
