The SEI Water Pump Impeller Kit is a cooling system component specifically designed for Mercury Outboard Motors, replacing the original OE# 47-19453Q2 part. It is manufactured from high-quality materials to ensure proper circulation of engine cooling water, thereby preventing engine overheating.
Water Pump Impeller Kit Advantages and Features
- Effective Cooling Performance: Ensures high-flow water circulation, keeping the engine cylinder block and head at optimal operating temperatures.

- Stainless Steel Plate and Housing: Includes a stainless steel wear plate and housing within the pump body to prevent abrasion.

Application and Usage
The impeller and water pump kit should be replaced if no water comes from the engine's tell-tale (pee hole), if the engine overheats, or during each annual periodic maintenance.
Maintenance and Installation Recommendations
During impeller installation, the vanes must be bent in the direction of engine rotation. Applying a small amount of soapy water to the pump housing during installation prevents dry friction during initial startup.
Frequently Asked Questions
What is the difference between an impeller kit and a complete water pump kit?
An impeller kit includes only the impeller and gaskets; it is sufficient if there is no wear on the housing and cover. If there is wear, a complete kit should be preferred.
Is this kit an equivalent of which OEM number?
No, this product is an aftermarket (equivalent) product that is fully compatible with the original part. It replaces the original Mercury kit with OE# 47-19453Q2.
