Things to weigh up with the Yanmar 3YM30AE

Where the Yanmar is strong

  • Own-design engines with a strong reputation
  • Cheaper consumables/parts, widely available
  • Strong Australian distributor support
  • GM and YM series run to 3,600 rpm — higher rated speed than the lower-revving Vetus M4 engines, which can mean more noise at cruise.

The verdict

The Yanmar 3YM30AE is a sound choice in its own right — known for own-design engines with a strong reputation. For recreational and cruising owners in Victoria, the Vetus M3.29 makes its case on standard equipment — a high-output alternator and self-bleeding fuel — and on local backup rather than headline specs.
