Things to weigh up with the Volvo Penta D2-40

Where the Volvo Penta is strong

  • Lower cruising rpm and smooth running
  • Integrated engine-drive-controls system
  • Very large global dealer network
  • Parts are widely reported as more expensive and slower to source than rivals — a real lifetime-cost consideration.
  • D1/D2 small diesels are marinised Shibaura industrial blocks — comparable heritage to Vetus's marinised Mitsubishi blocks, despite the premium price.

The verdict

The Volvo Penta D2-40 is a sound choice in its own right — known for lower cruising rpm and smooth running. For recreational and cruising owners in Victoria, the Vetus M4.45 makes its case on standard equipment — a high-output alternator and self-bleeding fuel — and on local backup rather than headline specs. As the authorised Victorian Vetus distributor, Luxfords can advise on, supply and support it locally, with genuine parts.
