VETUS M4.45 – Marine Diesel Engine 42 HP

At 42 hp and 3000 rpm, the VETUS M4.45 is a naturally aspirated inline four-cylinder marine diesel engine with 1.76 L displacement. It uses indirect fuel injection, a 22.0:1 compression ratio, and EN 590 diesel fuel. The listed drivetrain options include 2:1, 2.4:1, and 3:1 ratios with Technodrive TMC60 or ZF15M transmissions, which should be matched to the vessel propulsion arrangement.

Indirect heat-exchanger cooling works with a 40 mm water-injected wet exhaust, and the forced-lubrication system has a stated 6.1 L oil capacity. The engine carries a 12V, 110-amp alternator and an SAE 5 flywheel housing. Dry weight is listed at 182 kg, making machinery-space capacity and engine-bed design important pre-installation checks.

Why Choose the VETUS M4.45 Marine Diesel Engine

The M4.45 marine diesel engine provides 42 hp from a 1.76 L naturally aspirated four-cylinder configuration. Its specified Technodrive TMC60 and ZF15M transmission options, three listed gear ratios, SAE 5 flywheel housing, 110-amp alternator, heat-exchanger cooling, and 40 mm wet exhaust give buyers defined comparison points. It differs from a saildrive-specific package through its listed transmission and reduction-drive options.
