Product Description
Mercury Quicksilver 15-47397A1 is a shim set used at the forward-gear bearing outer race in specified Mercury and Mariner outboard gearcases. The shims are selected during gearcase setup to position the bearing and gear assembly correctly.
Key Features
- OEM number: 15-47397A1.
- Forward-gear bearing outer-race location.
- Catalog thickness designations: .002, .003, .005 and .010 inch.
Compatibility and Fitment
A documented application is the Mercury V-200 2.5L 1991-only standard-rotation gear housing, serial numbers 0C291520 through 0D081999, position 54. Other gearcases must be checked against their own bearing and shim callouts.
Replacement and Installation
Use the measurements and setup procedure in the matching gearcase service manual to select the shim stack. Do not duplicate an old stack automatically after changing gears, bearings or the housing.
