Sierra 18-72000 Carburetor Float, Replaces Mercury Marine 1395-9594

The Sierra 18-72000 is a carburetor float built as a direct replacement for Mercury Marine outboard carburetors. The float is a small plastic component that rides inside the carburetor bowl, rising and falling with fuel level to regulate the needle valve and keep fuel delivery consistent during engine operation. It is designed for gasoline-powered outboard applications and is suitable for use in salt water environments.

Constructed of plastic in a multicoloured finish, the float is compact and lightweight, matching the original equipment dimensions so it drops into the carburetor bowl without modification. It directly replaces Mercury Marine part number 1395-9594, making it a straightforward swap when an original float has cracked, absorbed fuel, or lost buoyancy.
