Volvo Penta MD 2030
The Volvo Penta MD 2030 is a 29hp, normally aspirated three cylinder marine diesel engine based on the Perkins 103-10 base engine. A marine engine of advanced design manufactured from quality components.
The MD2030 is fitted with freshwater cooling as standard. This reduces internal corrosion and enables the engine to maintain a consistent and optimal working temperature under all conditions. To avoid galvanic corrosion the engine is equipped with the unique electrical insulation between engine and transmission.
Smooth running with very low vibration levels results from a dynamically balanced design incorporating a flywheel of high rotating mass and high efficiency rubber insulation. The engine’s high torque provides excellent operating characteristics to aid maneuvering, particularly in confined spaces.
How heavy is the Volvo Penta MD2030?
The different models of the Volvo Penta MD2030 weigh between 145 kg (320 lbs) and 153 kg (337 lbs). The dry weight of the standard engine equipped with both angles and straight reverse gear (MS2A or MS2L) is 145 kg (320 lbs). When the engine is equipped with the sail drive option (120S), the dry weight is 153 kg (337 lbs). Lubricating oil, coolant and any alternator upgrades will add to this weight.
