Key Benefits
Quiet & Comfortable Operation
Vibration and noise are minimized with a dynamically balanced design, efficient rubber isolation and an air-inlet silencer. Ideal for extended journeys and overnight boarding.
Low RPM and High Torque.
Confident response to strong pulling at low engine speeds, typical situations in the marinas and docking with headwinds and currents on the Baltic and North Sea.
Rugged Marine Construction
Sturdy rigid one-piece cylinder head, and strong engine block for saltwater and long service life in both leisure and light commercial use.
Efficient 115 A Alternator
Inherited electronic sensor, which allows a higher battery capacity. Provides over 35 amps at idle and around 100 amps at cruising power – for modern electronics.
Freshwater Cooling as Standard
A closed freshwater system with a heat exchanger helps to minimize internal corrosion, keeping the operating temperature stable, thus contributing to engine life and maintenance.
Easy Service Access
Convenient location of oil change pipe and oil change service points and filters. Works with the real Volvo Penta parts that are offered by the wide dealer network in Germany and Europe.
