The Volvo Penta D4 Marine Engine

The D4 engine has been a stalwart of boating since its introduction in 2005. Like the D6 engine the unique, ground up design of the D4 was specifically for marine use. The marine focused torque profile ensures vessels are on the plane sooner and are using much less fuel; coupled with easy service points and Volvo Penta’s extensive warranty, it’s easy to see why this much-loved engine is so popular around the Australian coastline. Refreshed with stronger internals and a new control system the D4 is a reliable solution reliably powering leisure and commercial applications.

Features and Benefits

The D4 / D6 range of engines are specifically designed for marine applications. This delivers unique marine torque, with high torque at low rpm to get you out of the hole, onto the plane and allowing fast maneuverability, while enabling efficient cruising speeds. The common rail fuel injection system, intelligent EVC system and extended service intervals all contribute to efficient and easy boating experience in the best and worst conditions.

  • Fuel efficient, robust engine design
  • Specifically designed for marine applications
  • Compact and durable
  • Electronic Vessel Control with features and options
  • Ease of maintenance
  • Commercial and Leisure applications
