The MerCruiser 140 hp catalogues cover several closely related variants. To identify the correct MerCruiser 140 hp parts, first select the catalogue matching the engine code, year and serial number range shown on your engine.

This family includes catalogues for the GM 181 I_L4 engine from 1968 to 1972, from 1972 to 1978, from 1979 to 1982 and from 1982 to 1986, each associated with a distinct serial number range. It also includes a GM 194 I_L6 catalogue for 1963. These details help distinguish the exploded views and MerCruiser spare parts references.

Before consulting a MerCruiser diagram or exploded view, carefully note the serial number and identification details available on the engine. An incorrect period or serial range may lead you to a catalogue that does not match your configuration.

Once the exact variant has been identified, browse the exploded views to locate the required mechanical group and check the part reference. This makes it easier to find parts for the MerCruiser 140 hp engine in the correct catalogue.

Identify the exact MerCruiser 140 hp engine variant by its year, engine code and serial number before consulting the diagram.
