More about this item

EMP 46-00049 Water Pump Base

This water pump base is built for early MerCruiser inboard/outboard applications, specifically the 2.5L and 3.0L 4-cylinder 120-140 hp engines and the 4.5L V6 160 hp MC-1 Drive units from 1967 through 1969. It fits gear housings with a flush, screw-in design, so make sure your housing matches that configuration before ordering.

It's a direct replacement for Mercury OEM part 48748A1. The base forms the foundation of the water pump assembly, sealing against the gear housing and providing the mounting surface for the pump components above it. Getting this piece right matters for keeping your cooling system sealed and flowing properly.

Compatible Applications:
MerCruiser 2.5L-3.0L, 4-cyl, 120-140 hp (1967-1969)
MerCruiser 4.5L V6, 160 HP MC-1 Drive (1967-1969)
Requires flush, screw-in gear housing

Replaces OEM Part Number: Mercury 48748A1
