Mercury Marine 8M0077147
WATER PUMP BASE ASSEMBLY
This part sits in the cooling-water pump stack and typically requires removing the lower unit to service, so rework is costly and leaks can have serious consequences. The OEM assembly is application-specific and most likely to deliver correct water-passage alignment and durable sealing with the included gaskets and pre-installed seal.

OEM Mercury/Quicksilver water pump base assembly (assembled in the USA) with a molded housing and pre-installed shaft seal. Includes the application-specific fiber-style gaskets and O-ring intended to match Mercury water-passage alignment and sealing requirements.

Aftermarket pump base kit with molded housing and pre-installed seal, but it is not a 1:1 match to the Mercury 8M0077147 kit and is labeled as replacing a different OEM number. The mixed gasket set (including an extra paper-style gasket and unmarked fiber gaskets) suggests a multi-application approach, so careful application verification is important to avoid sealing or passage-misalignment issues.
