Engineered Marine Products Water Pump Impeller for Mercury Mariner Outboards Impellers

This water pump impeller from Engineered Marine Products is a replacement part for the raw water cooling system on Mercury and Mariner outboard motors. The impeller sits inside the water pump housing and pushes cooling water through the engine. Replacing it on schedule helps the engine hold a steady operating temperature and avoid overheating.

Key Features:

• Replacement outboard cooling water pump impeller for Mercury and Mariner outboards
• Flexible vanes made to seal against the pump housing and keep water flowing
• Made as an aftermarket alternative to the original impeller
• Several part numbers are offered in this product line, including 6-blade designs, so you can match the impeller to your outboard's pump

A worn impeller is a common cause of weak water flow and overheating in outboard motors. Replacing it as part of regular maintenance helps protect the powerhead and lower unit. Match the part number to your motor's water pump before you order.
