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.

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.
