Vetus M4.35 vs Bukh DV36 RME
The Vetus M4.35 is a 33 hp 4-cylinder marine diesel aimed at medium sailboats and powerboats, and a common alternative to the Bukh DV36 RME. The Vetus is a 4-cylinder and the Bukh a 3-cylinder unit. The Bukh rates slightly higher on paper (36 hp vs 33 hp), though both target similar vessels, so drive options — the Vetus offers a saildrive — along with weight and support are what set them apart.

Things to weigh up with the Bukh DV36 RME
Where the Bukh is strong
- Genuine own-design, heavy-duty continuous-rated marine engine
- SOLAS/DNV approvals, multiple redundant starting systems
- Built for commercial, lifeboat and rescue duty
- Premium commercial/safety-grade pricing — substantially more engine (and cost) than a recreational vessel typically needs.
- Heavy for the power output (e.g. ~210 kg for a 24-32 hp DV) versus much lighter recreational diesels.
- Shaft-drive only; no saildrive option for sailboat installs.
The verdict
The Bukh DV36 RME is a sound choice in its own right — known for genuine own-design, heavy-duty continuous-rated marine engine. If your vessel genuinely needs heavy-duty, continuously-rated, SOLAS-grade power, Bukh is purpose-built for it. For most recreational and cruising owners, though, the Vetus M4.35 offers the better balance of performance, lighter weight and saildrive flexibility for leisure use — and it's backed locally by Luxfords here in Victoria.
