Velvet Drive 13.25” Damper Plate 1004-650-007
Part Number: 1004-650-007 (Velvet Drive / Borg-Warner)
The Velvet Drive 1004-650-007 is a 13.25-inch replacement damper plate for compatible Velvet Drive marine transmission installations. The damper plate mounts between the engine flywheel and the transmission input, absorbing torsional vibration and smoothing power transfer from the engine to the marine gear. It is the correct replacement when 1004-650-007 is specified on the transmission or installation documentation.
Specifications
- Outside diameter: 13.25 in.
- Weight: 3.5 kg
Compatible Applications
- Velvet Drive transmissions paired with GM 454 marine engine configurations requiring a 13.25” damper plate
- Velvet Drive transmissions paired with Ford Lehman marine engine configurations requiring a 13.25” damper plate
Fitment Notice
Damper plates can appear similar but vary significantly by outside diameter, bolt pattern, hub spline count, hub depth, spring configuration, and offset. Diameter alone is not a reliable fitment reference. Confirm the following before ordering:
- Engine model (GM 454 or Ford Lehman)
- Flywheel diameter and bolt pattern
- Transmission model and input configuration
- Original damper plate number: 1004-650-007
- Hub spline count and depth
Cross-Reference Part Numbers
- Velvet Drive / Borg-Warner: 1004-650-007
When to Replace the Damper Plate
- Damper springs are loose, broken, or missing
- Hub splines are worn or damaged
- Plate body is cracked or bent
- Rivets are loose or sheared
- Driveline shows excessive rattle, vibration, clunking, or poor engagement feel under load
- Transmission is being removed for overhaul and plate inspection reveals wear
Installation Notes
- Remove the transmission according to the manufacturer’s service procedure before accessing the damper plate
- Inspect the flywheel surface and ring gear for wear or damage while the transmission is off
- Verify the replacement plate matches the original in diameter, bolt pattern, hub spline count, and depth before installation
- Install the plate squarely against the flywheel and torque all fasteners evenly to specification
- Confirm full spline engagement with the transmission input shaft before closing up
- Check bellhousing alignment and mounting hardware during reassembly
- Replace any disturbed transmission oil seals or gaskets during reassembly

Parts Desk Insights
The 1004-650-007 damper plate is the correct choice for Velvet Drive installations on GM 454 or Ford Lehman-powered vessels where the transmission or installation manual specifies this part number and a 13.25-inch plate. It is a fitment-sensitive component that comes up most often during transmission removals, overhauls, or when driveline vibration and rough engagement point to a worn or broken plate.
The most common ordering mistake is selecting a damper plate by outside diameter alone. The 13.25-inch dimension confirms the overall size, but the bolt pattern, hub spline count, hub depth, and spring configuration must all match the original. A plate that is dimensionally close but not the correct specification can cause misalignment, vibration, or engagement problems after installation. Always confirm against the original part number stamped on the plate or listed in the transmission documentation before ordering.
