Key Features and Advantages of the Vetus M3.29
Optimized Power and Fuel Efficiency
Delivering 27HP at 3600 RPM, the M3.29 offers excellent acceleration and reliable cruising power for sailboats and compact vessels. With its lightweight 3-cylinder design, it ensures smooth handling, low fuel consumption, and extended cruising range, ideal for long-distance marine travel.
Advanced Cooling and Noise Reduction
The cast-aluminum water-cooled top cover reduces engine temperature by up to 15°C (a 20% improvement). Combined with a noise-dampening air intake filter, this system lowers operational noise levels by approximately 5 dB(A), creating a quieter and more enjoyable onboard environment.
Efficient Fuel System with Self-Bleeding Technology
The self-bleeding fuel system simplifies engine startup after maintenance, while the high-pressure indirect injection optimizes fuel atomization for cleaner combustion. This results in lower emissions, improved efficiency, and full compliance with EU-RCD II, BSO, and SOLAS marine standards.
Rugged and Space-Saving Design
The heavy-duty 3-cylinder engine block offers exceptional reliability and strength, while the compact footprint makes it perfect for installation in tight engine compartments. Engine mounts and flexible couplings minimize vibration, extending the lifespan of onboard systems.
Strong Electrical Output for Marine Systems
Equipped with a 12V / 75A alternator, the M3.29 provides rapid battery charging and a stable electrical supply for navigation, lighting, and auxiliary equipment. The pre-wired harness and waterproof connectors ensure simple installation and improved safety.
Flexible Mounting and Transmission Options
Compatible with multiple gearbox and saildrive configurations, including TMC, ZF, and SOLAS-approved systems, the M3.29 adapts easily to different propulsion requirements. Optional keel cooling and calorifier connection kits allow full customization for various vessel types.
Built for Reliability, Efficiency, and Ease of Maintenance
Every Vetus M3.29 engine is designed for long service life and low maintenance. With easily accessible filters, a self-bleeding fuel system, and simplified hose routing, maintenance becomes quick and cost-effective. The indirect cooling system ensures stable operating temperatures, even in warm or contaminated water conditions.
This engine’s robust design and engineering precision make it one of the most trusted 3-cylinder marine diesel engines in the market today.
