MerCruiser 4.3 Parts Catalog

HOW TO SEARCH MERCURY MARINE PARTS DIAGRAMS

Option 1 - Using the new Mercury diagrams and catalog you can search all of the inboard, sterndrive and outboard parts and accessories. These diagrams cover all products and Model Year.’s

Option 2 - Using the original, older Mercury diagrams and catalog you can search all of the inboard, sterndrive and outboard parts and accessories. However, these diagrams only go up to the 2011 Model Year.

Note - Both diagram tools will provide the same parts results up to the 2011 model year, but with a different layout using the older diagrams vs the new diagram layout. However, for all models 2011 and later only the new diagrams (option 1) will contain those parts.

MerCruiser 4.3L V6 Sterndrive Engines

The 4.3L V6 Engine was not the 1st 6 cylinder Sterndrive engine offered by MerCruiser. The Inline 6 cylinder engines date back to the 1963 with the 194 model. During the 1970's MerCruiser offered the 225 Cu-In inline 6 cylinder engine which many engine parts are still available today and easy to find using our MerCruiser OEM parts lookup Diagrams and Catalogs. You will find common maintenance items including oils, lubricants and complete tune up kits as well as Seloc Service Manuals. By far the most popular engine today in the 6 cylinder engine family is the MerCruiser 4.3 which is offered only within the Sterndrive Engine model family. The original 4.3L Engine Model was released around 1985 as a non-balanced-shaft engine in the carbureted engine model family. This original version of MerCruiser 4.3 Engine was equipped with a mechanical fuel pump however in 1992 with Gen II series engines the fuel system was upgraded to include an electric fuel pump as well as standard engine mounts due to the introduction of the balanced shaft engine design to address the inherant vibration issues associated with 90 degree V6 engine configurations. In 2014 MerCruiser released their 4.5L V6 engine models....Read More which will be used to phase out the 4.3L V6 engine models over the next few years as GM discontinues production on this model.
