About the M3.29
The Vetus M3.29 steps up to a three-cylinder configuration, delivering 27 HP with notably smooth power delivery and strong low-end torque. This engine is the most popular choice in the M-Line range, offering the ideal balance of power, weight, and fuel efficiency for medium-sized cruising sailboats and light displacement powerboats.
The M3.29 features Vetus' water-cooled aluminium top cover, reducing engine room temperatures by 15–20°C — a reduction of approximately 20% compared to engines with conventional air-cooled covers. The engine achieves near-silent operation at a cruising speed of around 2200 RPM, with noise levels among the lowest in its class. HVO-approved and SOLAS certified, the M3.29 meets modern environmental and safety standards.
Available in standard shaft-drive and saildrive variants, the M3.29 adapts to virtually any installation. Luxfords carries comprehensive stock of M3.29 engines and components, providing fast availability and expert technical guidance on engine selection, saildrive configuration, and installation planning.
