Quicksilver OEM Washer — Part No. 29245
- Part Number: 29245
- Current Superseding Number: 8M0204649
- Brand: Quicksilver (Genuine Mercury Marine OEM)
- Type: Washer
- System: Hardware / Fasteners — broad application across Mercury and MerCruiser assemblies
What This Part Does
This genuine OEM washer provides correct load distribution, stack height, and spacing in the fastener assembly where the Mercury or MerCruiser parts diagram specifies 29245 or its current superseding number 8M0204649. The correct washer thickness and diameter directly affect clamping force and alignment — a generic substitute that differs in any dimension can compromise how the joint performs under vibration and load in a marine environment.
Supersession note: Mercury has assigned 8M0204649 as the current active replacement for 29245. If your parts diagram shows 29245, this is the correct OEM replacement. If sourcing the current number, search for 8M0204649.
Compatible Applications
- Any Mercury or MerCruiser assembly where the current parts diagram specifies 29245 or superseding number 8M0204649
Always confirm the exact diagram position using your engine or drive model and serial number before ordering — this washer appears across multiple Mercury and MerCruiser assemblies and the diagram position matters.
When to Replace
- Washer is missing from the assembly
- Corrosion, bending, flattening, or distortion visible
- Washer no longer sits correctly in the fastener stack
- Assembly is being disassembled for service and hardware renewal is appropriate
Installation Notes
- Confirm the washer’s exact position in the Mercury parts diagram before installation
- Match with the correct fastener for the assembly being serviced
- Tighten the associated fastener to the torque specification in the Mercury service manual for your application

Parts Desk Insights
The most practical thing to know about 29245 is that Mercury has superseded it to 8M0204649 — if you’re sourcing this part, either number should get you to the correct OEM washer. As with all small Mercury hardware, order by the part number from your diagram rather than trying to match by appearance or caliper measurement. The correct OEM washer maintains the intended clamp load and stack height; a washer that’s slightly off in thickness or diameter can affect how the assembly torques and seats.
