Revitalize Your OMC Cobra Cooling System with a Complete Rebuild Kit

GHmarine presents a complete water pump repair kit designed for OMC Cobra stern drives. Built to support engines from 2.3L through 7.5L, this kit is tailored for interval maintenance and on‑site rebuilds. It covers assemblies from the mid 1980s to the early 1990s, aiming to restore steady coolant flow and reduce the risk of overheating. The kit also lists compatible references and replacement numbers to help you plan maintenance with confidence.

Specifically, this is a full rebuild set that helps you address common wear and seal challenges in the cooling loop. By replacing worn parts with a matched set, you can approach a more consistent pump operation and a clearer path for cooling water to reach the engine. While it does not guarantee results in every situation, many operators find a rebuild reduces nuisance leaks and simplifies service in the field or shop.
