Start by noting the information shown on the engine identification plate, then open the category matching the model and range indicated. This check helps prevent errors when consulting MerCruiser exploded views and diagrams.

Once the correct catalogue has been selected, the diagram helps you locate the required part and identify its reference. You can then browse the MerCruiser spare parts associated with the exact variant of your 120 hp engine.
