Craftsman CM3.27 – Marine Diesel Engine 27 HP

At 27.3 hp and 3600 rpm, the Craftsman CM3.27 combines a 1.32 L inline three-cylinder layout with indirect diesel injection and naturally aspirated induction. It is specified for EN 590 diesel and uses an SAE 5 flywheel housing with a Technodrive TMC 40 or TMC 60 mechanical gearbox. This configuration should be matched with the selected shaft-drive and propeller arrangement before installation planning begins.

The engine has a listed dry weight of 145 kg, a 12V, 70-amp alternator, and mechanical or hydraulic steering compatibility. Indirect heat-exchanger cooling pairs with a 40 mm water-injected wet exhaust. Its forced-lubrication system holds 4 L of oil, while the cooling circuit has a stated 4.5 L capacity.

Engine and Mechanical Gearbox Layout

This Craftsman marine diesel engine has a 78 x 92 mm bore-and-stroke specification, a 22.0:1 compression ratio, and firing order 1-3-2.
