Engineered Marine Products OMC Water Pump Impeller Impellers

Engineered Marine Products OMC water pump impellers are replacement outboard water pump impellers for OMC-style outboard and sterndrive cooling systems. The impeller is the flexible, vaned rubber part inside the raw water pump. It draws water through the lower unit and sends it to the engine to carry away heat. A worn impeller can cause overheating, so replacing it is a basic part of outboard maintenance.

Key Features:

• Replacement impeller for the raw water pump in OMC-style marine cooling systems
• Flexible vanes seal against the pump housing to keep water flowing
• Made as an aftermarket replacement for the original OMC impeller
• Suitable for routine service and for rebuilding the water pump
• Available in several part numbers within the product line

Replacing the impeller on schedule helps keep engine temperatures stable and protects your powerhead. It is a good time to also inspect the pump housing, face plate and seals. Select the part number that matches your engine from the variants listed on this page.
