OEM Water Pump Face Plate for Mercury & MerCruiser Assemblies
This genuine Mercury Marine water pump face plate is a precision wear component used in Mercury outboard and MerCruiser sterndrive water pump assemblies. The face plate forms part of the pump's wear surface — when it's scored, corroded, or worn, the pump can't maintain proper cooling flow. Replacing it during water pump service restores the correct sealing surface and protects the impeller and housing from accelerated wear.
Key Details

- Related References: 32435B, 324351, 30605
- Type: Water Pump Face Plate / Wear Plate
- Genuine OEM — not aftermarket
Common Applications
This face plate fits Mercury and Mariner water pump gearcase service across many older 4-cylinder, 6-cylinder, and V6 outboards in the 65–225 HP range, as well as select MerCruiser R, MR, and Alpha One sterndrive gear housing applications. Always verify fitment using your engine or drive serial number and the correct water pump / gear housing parts diagram before ordering — this plate appears across a wide range of assemblies.
When to Replace
Replace the face plate when the water pump service area shows scoring, wear, corrosion, or overheating-related damage, or whenever the pump is already apart for impeller and housing service. Reusing a worn or damaged face plate during a water pump rebuild is a common cause of repeat failures.
Installation Notes
Confirm the exact Mercury or MerCruiser water pump diagram for the unit being serviced before installation. The face plate is part of a complete pump stack — match it to the correct pump body, insert, seal, impeller, key, screws, and washers during reassembly. Note that 8M0204677 is the current active replacement for 32435 and may be substituted where the diagram calls for either number.

Parts Desk Insights
Best use case: Water pump rebuild or impeller service on Mercury outboards (65–225 HP) and MerCruiser R/MR/Alpha One sterndrives where the parts diagram calls for 32435 or its current replacement 8M0204677. This is the part most often overlooked during a pump rebuild — technicians replace the impeller but skip the face plate, only to find the new impeller wearing prematurely against a scored surface. If the pump is already apart, replacing the face plate at the same time is the right call. Always match by serial number and diagram, not horsepower alone — small pump parts can look similar across families.
