Sierra 18-2563-9 Impeller Gasket, Replaces Honda 19232-ZW1-003, Fits BF8/BF9.9/BF15/BF20 Outboards - Pack of 2

The Sierra 18-2563-9 Impeller Gasket is a glass-material gasket engineered to seal the water pump housing on select Honda BF-series outboards. Sold in a pack of 2, it gives owners a spare on hand for the next scheduled water pump service, since impeller gaskets are a wear item that should be replaced whenever the housing is opened. Each gasket is manufactured to meet or exceed original equipment quality, so it seals and fits like the factory part it replaces.

This gasket fits Honda BF8 outboards from 2002 and up, BF9.9 outboards from 2002 and up, and BF15 and BF20 outboards from 2003 and up. It directly replaces the Honda OEM gasket numbered 19232-ZW1-003, making it a straightforward drop-in during impeller replacement or general water pump maintenance. At 0.25 inches thick, it is sized to match the original gasket's sealing profile.
