Yanmar 6HA2M-WHT Marine Engine

The Yanmar 6HA2M-WHT marine engine is a robust, high-speed diesel propulsion solution designed for commercial vessels that demand durability, efficiency, and dependable continuous operation. Built on Yanmar’s proven HA-series platform, this 6-cylinder engine combines strong torque output with simple mechanical reliability, making it an excellent choice for fishing boats, workboats, ferries, patrol vessels, and small cargo craft.

At the core of the 6HA2M-WHT is a direct-injection diesel combustion system engineered to deliver efficient fuel utilization and consistent performance across a wide operating range. The engine features a heat-exchanger cooling system for stable thermal management in demanding marine environments, while its heavy-duty construction ensures long service life even under high load conditions. With multiple available power ratings reaching up to approximately 405 mhp, operators can select the configuration best suited to vessel size and duty cycle requirements.

The engine is compatible with hydraulic multi-disc marine gear options that provide smooth engagement, flexible reduction ratios, and reliable propulsion control. Its compact footprint and relatively lightweight design for its power class simplify installation in both new builds and repower projects. Maintenance accessibility is also a key advantage, with service points designed for practical onboard servicing to minimize downtime and operating costs.

Compliant with IMO Tier II emission standards, the 6HA2M-WHT balances environmental responsibility with proven mechanical performance. This combination of fuel efficiency, durability, and straightforward engineering makes it a trusted propulsion engine for operators who prioritize reliability and long-term operating value in commercial marine applications
