features & benefits

Compact power, full flexibility

Unlock new levels of flexibility and performance at sea. The Volvo Penta D4-175 VG is a light, compact 3.7-liter diesel genset designed specifically for marine use, offering high electrical output, excellent efficiency, and seamless onboard power management.

Operate smarter, save more

 The D4-175 VG offers full operational flexibility: it can run at multiple fixed speeds or at fully variable speeds to match electrical load. This results in significantly improved fuel efficiency, lower emissions, and optimized engine performance across all operating conditions.

Compact, robust and marine-classed

With a small footprint and low weight, installation is simple even in tight engine rooms. The permanent magnet generator (PMG) technology ensures a compact, robust, and efficient power source. 

Easy installation and integration

Flexible coupling, flexible mountings, and the ability to mix engine sizes eliminate the need for genset synchronization. Quick-connect low-voltage wiring, IP65 protection, anti-condensation heater, and advanced temperature sensors ensure a fast and reliable setup — ready for demanding marine environments.

Marine-grade durability and performance

The D4-175 (VG) features a cast-iron engine block, 4-valve technology, common rail fuel injection (2000 bar), oil-cooled pistons, a seawater-cooled tubular oil cooler, and a maintenance-free crankcase oil separator. It's engineered for maximum uptime, reduced maintenance, and reliable performance over the long haul.
