KEY FEATURES
Heat and Noise Reduction (M-Line Engineering): Features a cast-aluminum, water-cooled upper top cover that absorbs radiant engine heat, reducing engine room temperatures by up to 15–20°C (a 20% reduction). Combined with a state-of-the-art air filter intake system, it cuts operational noise by 5 dB(A), running "near-silent" around a cruising speed of 2,200 RPM.
Self-Bleeding Fuel System: The fuel loop is automatically self-bleeding, meaning you do not have to manually bleed air out of the system after a fuel filter replacement.
HVO Approved: The engine is officially approved to run on Hydrotreated Vegetable Oil (HVO). This sustainable, low-carbon fuel alternative can reduce exhaust emissions (CO2, CO, HC, NOx, and PM) by up to 90%.
High-Output Charging: Equipped with a heavy-duty 110A marine alternator as standard equipment, ensuring rapid recharging of onboard house and starter battery banks.
Service Safety & Convenience: The heavy-duty aluminum top cover doubles as a secure step, allowing for safer and easier mobility around tight engine compartments. Service items like oil and fuel filters are strategically positioned on one side for easy maintenance access.
