- Gasket/seal set specifically for the gear-shift mechanism on a broad range of Volvo Penta stern drives.
- Application includes 275A, 280-family, 285A, 290-family, SP-A/SP-C families and multiple DP/DPX drives.
- Used when the shift-mechanism housing is removed or resealed during stern-drive service.
- Helps prevent gear-lube leakage and water intrusion at the shift-mechanism interfaces.
- Identify the exact drive model before disassembly and inspect the shift shaft/mechanism for corrosion or wear while accessible.
Fitment for marine engine and drive service parts can vary by model, serial number, gearcase, cooling configuration and prior component supersessions. Compare the original OEM number and physical configuration before installation, and renew related seals, locking hardware or adjacent wear items when their condition requires it.
