Yamaha Upper Driveshaft Seal 28019
The 28019 Upper Driveshaft Seal replaces Yamaha OEM part numbers 93101-28019-00, 93101-28018-00, and 93101-28004-00. This seal is used in Yamaha lower unit gearcases to prevent water intrusion and retain gear lube around the driveshaft.
Fitment Overview
This seal is confirmed through Yamaha OEM lower unit diagrams and is used across both 4.2L V6 and 5.3L V8 outboard platforms. It is installed at the top of the driveshaft in the gearcase assembly.
Compatibility
| Engine Model | Horsepower | Engine Platform |
|---|---|---|
| F200 / LF200 | 200 HP | 4.2L V6 |
| F225 / LF225 | 225 HP | 4.2L V6 |

| F350 / LF350 | 350 HP | 5.3L V8 |
Fits These Serial Ranges

- 4.2L V6 outboards (modern production models)
- 5.3L V8 F300 and F350 models beginning in 2007
Important: Because Yamaha uses multiple seal variations depending on gearcase design, always verify using your exact model and serial number before ordering.

What This Shift Shaft Seal is Used For
This shift shaft seal is installed in the lower unit to seal around the shift shaft where it passes through the gearcase housing or seal carrier.
A properly sealing shift shaft seal helps keep water out of the lower unit and helps keep gear lubricant inside the gearcase during operation.
Shift shaft seals are commonly replaced during lower unit resealing, water intrusion repair, shift shaft service, or complete gearcase rebuilds.
Replacing worn, hardened, or leaking seals can help protect internal gears, bearings, and shafts from water-contaminated gear lube.
