VOLVO PENTA INBOARD DIESEL
3-cylinder, freshwater-cooled marine diesel engine
MD2030
Crankshaft power* 20.9 kW (29 hp)
* Crankshaft power according to ISO 8665
The MD2030 is a marine engine
of advanced design manufactured
from quality components and de-
signed to fulfil customer require-
ments.
Service Life
The MD2030 is fitted with freshwa-
ter cooling as standard. This reduc-
es 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.
Comfort
Smooth running with very low vibra-
tion levels results from a dynamical-
ly balanced design incorporating a
flywheel of high rotating mass and
high efficiency rubber insulation.
