Quicksilver water pump impeller 47-89984T4 is an original impeller for the cooling water pump in documented Mercury outboard motors and MerCruiser drives. The impeller is manufactured to Mercury Marine's OEM specifications and is used to maintain cooling water flow through the engine's cooling system.
The flexible elastomer impeller vanes are designed to retain their flexibility at varying temperatures. A brass center insert is designed to resist tearing, while the durable construction supports a stable cooling water flow.
The impeller fits, among others, Mercury OptiMax 2.5L non-Pro from serial number 1B227000, Mercury 2.5L EFI and EFI Offshore, as well as selected Mercury Racing 200 EFI, 200XS, 225 EFI, 225X, S2000, and SST 120 models. Documented applications also include MerCruiser R/MR and Alpha One drives from 1983-1990 with serial numbers 6225577 to 0F386995.
The spare part replaces the previous OEM numbers 47-30221, 47-65960, 47-85460, 47-89984, 47-899842, 47-899844, and 47-89984B2. Since the application depends on engine model, drive, and serial number, the existing spare part number and the specific serial number group should always be checked before ordering.
