V8 performance in a V6 package
The M300 engine is based on the existing high-power Honda BF250 marine platform. Using its precision engineering technology expertise, McLaren Engineering is performance-tuning base models for enhanced top-end power and mid-range torque. The result is a performance-inspired outboard that delivers enhanced top-end power of 300 hp – with the premium quality, outstanding reliability and durability you expect from a Honda outboard.
Precision Engineering for Enhanced Power
McLaren Performance modifications include the integration of a new camshaft for enhanced valve timing and high lift; a new Engine Control Unit (ECU) that controls protection and boosts efficiencies (IG mapping, knock control); new fuel injectors for higher fuel supply; and excellent fuel efficiency (3.5+ MPG @cruise, 90 octane).
Powerful Performance
Power where and when you need it.
Honda’s exclusive VTEC technology offers a superior combination of power, torque, and fuel economy.
Quiet performance
The M300 offers Honda’s legendary quiet performance. Meaning you get to enjoy more of the great outdoors, and less engine noise.
Dual channel, indirect-air-circuit induction system
The dual channel, indirect-air-circuit induction system in the cowling improves airflow, enhancing performance while helping funnel moisture away from the throttle body.
