Volvo Penta has released a major update of its D13 engine and IPS 1350 pod drive to make them even better at powering large semi-displacement motor yachts – and at a more leisurely pace.
Of note, the Volvo Penta D13 propulsion system’s torque can now cope with higher thrust loads at slower speeds, while the IPS 1350 pod drive is now tuned to a top speed of 19 knots, a big reduction over the former unit’s 25-knot upper limit.

The new drivetrains also bring two new propellers; the QS4 and QS5 made specifically for the D13.
“One of the key advantages of the new edition D13 propulsion system is that a wider range of boaters can use the IPS features which were previously not available for larger semi-displacement yachts,” Volvo Penta said in a statement announcing the revised powerplant.
“The key advantages of the Volvo Penta IPS, compared to inboard shaft installations are the increased onboard comfort, increased fuel efficiency and longer range.
“As an integrated marine propulsion system, the Volvo Penta IPS also delivers an intuitive onboard experience through simple joystick control,” it said.
The individually steerable IPS drives – controlled by the joystick – make for ultra-responsive handling and pilot-like control when maneuvering and docking.
“This allows owners to navigate in tight spaces, perform tricky maneuvers and maintain outstanding stability in all sea conditions.”
Volvo Penta product manager Björn Rönnvall said slowing down the top speed of the IPS 1350 was in response to a growing trend for large yachts to cruise at a more relaxed pace.
Luxury motor yachts including the the Absolute Navetta 73, ISA 93 Extra and the Arcadia Sherpa XL all use the new engine, while the Magnusta Gransport 33 – set to make its debut at the 2020 Cannes Yachting Festival in April – will also feature it.
The Volvo Penta IPS1350 system is optimised for yachts from 60ft to 120ft. The 1000hp 12.8-litre in-line six-cylinder D13 is the most powerful pod drive engine Volvo Penta produces.
