Mercruiser Marine Engines

Which MerCruiser Fits Your Boat?

Owners often ask for MerCruiser marine diesel engines by name, so a quick note first: the engines listed here run on petrol, in familiar sizes from 200 hp to 450 hp. Family cruisers, sport boats and bigger runabouts are all covered, which suits buyers with a simple goal: replace what is already there.

The litre figure, such as 4.5L, 6.2L or 8.2L, tells you the engine’s size
Alpha and Bravo name the drive at the stern that the engine is built to match
Numbers like 8M0136293 are part codes, handy for matching an exact replacement
Power shows as hp or PS, two measures that are almost the same

Can I Match My Current Engine?

Often you can, and it starts at home. Read the size and drive name on your current engine, then look for the same pairing in the list. A matching size and drive is the best sign of an easy swap.

Which Size for Which Boat?

4.5L (200 to 250 hp): lighter cruisers and everyday family boats
350 MPI (300 hp): a balanced middle ground for sport cruisers
6.2L (300 to 350 hp): confident power for heavier hulls and busy weekends
8.2L (380 to 425 hp): serious pull for big sport boats and fast cruisers
540 (450 hp): the strongest in the list, for demanding high-speed use
