Engineered Marine Products Water Pump Impeller

The Engineered Marine Products Water Pump Impeller is a replacement outboard cooling system part. It is also called a raw water pump impeller or water pump vane impeller. The impeller sits inside the water pump housing and spins with the drive shaft. It draws water from the lower unit and pushes it through the engine's cooling passages, which helps keep operating temperature under control.

Key Features:

• Replacement impeller for outboard engine cooling water pumps
• Flexible vane design that moves water as the pump turns
• Supports steady cooling water flow when the pump is in good condition
• A common wear item that is serviced as part of regular outboard maintenance

A worn, cracked, or hardened impeller can reduce water flow and lead to overheating, so replacing it on schedule helps protect the engine. Engineered Marine Products offers this impeller line as an aftermarket replacement for outboard owners and marine technicians. Choose the individual part number from the options on this page.
