VOLVO PENTA INBOARD DIESEL

TAMD74LEDC
6-cylinder, 4-stroke, direct-injected, turbocharged marine diesel engine
with aftercooler – crankshaft power* 316 kW (430 hp)
* Power rating – see Technical Data

Powerful performance
The TAMD74L EDC marine diesel is specially
developed for fast planing and semi-planing
craft. The engine’s high output combined
with a rich torque curve ensures excellent
performance, acceleration and response. Its
compact dimensions optimizes boat layout,
minimizes impact on living space onboard
and improves service accessibility.
EDC – optimizing engine
performance
EDC (Electronic Diesel Control) – an elec-
tronically controlled processing system
that determines the precise quantity of fuel
required at any given moment. The EDC
system takes full account of variation in op-
erating temperature, air pressure and other
contributing factors, which optimizes engine
performance and efficiency, reducing fuel TAMD74L EDC
