About the M4.45

The Vetus M4.45 delivers 42 HP from the same compact four-cylinder block as the M4.35, providing significantly more power without increasing the engine's physical footprint. This makes the M4.45 an excellent choice for owners who need more performance from an existing engine bay, or for new builds where space is at a premium.

The engine maintains all the refinement of the M-Line platform — water-cooled top cover, low noise levels at cruising speed, and HVO fuel compatibility. The additional power output is achieved through optimised turbocharging and fuel delivery, giving the M4.45 strong acceleration and the ability to handle heavier displacement vessels confidently.

Available through Luxfords in shaft-drive and saildrive versions, the M4.45 is supported by comprehensive technical advice on engine selection, gearbox matching, and propeller sizing to ensure optimal performance for your vessel.
