Quicksilver Washer 34567
This genuine OEM washer is used in Bravo sterndrive exhaust and cooling system assemblies (serial 1G400000 and up). In these applications, washers like this provide the correct sealing surface, spacing, or load distribution between fastened components — and using the exact OEM part ensures the right dimensions and material for the assembly. A washer that’s slightly off in thickness or diameter can affect clamping load and sealing performance in a cooling or exhaust joint.
Key Specifications
- Part Number: 34567 (OEM ref: 12-34567)
- Type: Washer
- Known Application: Bravo – Exhaust / Cooling Systems and Extension Kits (serial 1G400000 & up)
- Genuine OEM — not aftermarket
Common Applications
Use this washer wherever the Mercury or MerCruiser parts diagram specifies part number 34567. It is documented in Bravo sterndrive exhaust and cooling system component groups for serial 1G400000 and up — always verify against your drive’s current parts diagram and serial number before ordering.
When to Replace
Replace if the washer is missing, corroded, crushed, flattened, or distorted, or whenever it is removed from a sealing or fastening joint during service. In cooling and exhaust assemblies, a compromised washer can affect sealing performance and lead to leaks.
Installation Notes
Clean mating surfaces before installation. Confirm the washer’s exact position in the Mercury parts diagram for your assembly. Follow the Mercury service manual for the correct torque specification and tightening sequence, and replace any related seals or gaskets disturbed during disassembly.

Parts Desk Insights
Best used as a direct OEM replacement during Bravo sterndrive exhaust or cooling system service where the parts diagram calls for 34567. This washer appears in a specific assembly group, so the safest match is the exact diagram location and serial number range rather than appearance alone. If you’re doing a full exhaust or cooling reseal, it’s worth ordering a spare — these small hardware items are inexpensive insurance against a repeat job. If your drive has been updated or repowered, cross-reference the current diagram to confirm this number hasn’t been superseded.
