🔌 Function

The flexible impeller creates the suction that pumps seawater through the engine's cooling circuit and the wet exhaust.

⚠️ Common Signs of Failure

• Cooling water discharge at the exhaust weak or absent
• Impeller blades cracked, set or missing
• Engine running hotter under load
• Broken blade pieces found downstream in the heat exchanger
• Annual or hour-based impeller service due

🛠️ Service Notes

• Read the engine designation carefully - the 2003 and the 2003T take different impellers and the numbers sit next to each other
• If blades have broken off, find them downstream before running the engine again
• Kit 877194 packs this impeller with the oil and fuel filters for the same engines
• Always refer to the operator's manual for the recommended maintenance and service intervals for your engine and drive
• Listed against more than one engine or drive family - check the qualifier that applies to your own engine or drive
