The Borg Warner 71-9C is an OEM-style case / planetary bushing for select Velvet Drive 71 and 72 series marine transmissions. Current transmission-parts references identify 71-9C as the bushing used in the planetary, where the input shaft rides inside the assembly.
Current references also note that this bushing helps seal forward clutch pressure inside the planetary assembly, making it an important internal transmission service part rather than a general external hardware item.
Key Features
- Borg Warner / Velvet Drive planetary case bushing
- OEM reference: 71-9C
- Used in the planetary assembly
- Supports the input shaft in the planetary
- Helps seal forward clutch pressure
Transmission Compatibility
Current supported references associate 71-9C with Borg Warner / Velvet Drive 71 and 72 series marine transmissions. Additional transmission-parts listings also show overlap into 1004, 1005, 1017, and 1018 series Velvet Drive applications.
Serial Number Fitment Notice
Fitment should be confirmed by transmission model, ratio, and internal parts breakdown before ordering. Matching by OEM part number 71-9C remains the safest method.
When This Part Needs Replacement
Replace the bushing if it shows scoring, wear, looseness, shaft play, or pressure-loss-related transmission issues during teardown. Because this is an internal planetary bushing, replacement is typically done during transmission rebuild or major internal service. This guidance is based on the part’s function; the reviewed sources mainly confirm identity and application.
Installation Notes
Current service-part references note that this bushing is sold individually. They also state that 2 are required per transmission, except for 2.10:1 and some early 1.52 ratio units with a rear seal holder, which may require 3.

Parts Desk Insight
This is one of those small internal transmission parts that does a lot of important work. The key detail is location: 71-9C is the planetary bushing for the input shaft, so correct quantity and ratio-specific fitment matter before ordering rebuild parts.
