Sierra Carburetor Rebuild Kit 18-7773, Replaces 5032424, Fits Johnson/Evinrude 25 & 30 HP Bosch Outboards

The Sierra 18-7773 Carburetor Rebuild Kit restores factory carburetor performance on applicable Johnson/Evinrude (OMC/BRP) outboards equipped with Bosch model carburetors. This kit is engineered to replace worn gaskets, seals, and internal wear components inside the carburetor so it returns to proper fuel metering and a clean, consistent idle. Carburetor rebuild kits like this one are the standard fix for outboards suffering from rough idle, hard starting, stalling, or poor fuel atomization caused by deteriorated carburetor internals, and rebuilding with a kit is typically far less costly than replacing the entire carburetor assembly.

This kit is designed for Johnson/Evinrude (OMC/BRP) outboards using Bosch model carburetors, specifically 25 and 30 HP applications covering the 2000-01 model years as well as 2004 and up. It directly replaces OEM part number 5032424, so it is a straightforward drop-in rebuild solution for anyone servicing these engines rather than sourcing a completely new carburetor.
