MerCruiser 225 hp engine parts: choose the right catalogue

Identify the catalogue variant before viewing the parts

Logo MerCruiser

To find the correct part number, start by identifying the exact variant of the MerCruiser 225 hp engine. This family includes six catalogues distinguished by engine configuration, model year and serial number range.

The variants include GM 327 V-8 or Ford 302 V-8 engines, 2 bbl. or 4 bbl. configurations, and MIE and 225-S versions. The periods covered run from 1963 to 1974, with serial number ranges specific to each catalogue.

Before opening a MerCruiser exploded view or diagram, compare the variant name with the information recorded on the engine. In particular, check the model year and serial number so that you consult the corresponding catalogue and identify the spare parts suited to this reference.

Related categories cover other MerCruiser power outputs. If your engine is not a 225 hp, return to the 8-cylinder engine family and look for the stated power output before selecting the appropriate catalogue.
