Triple Carburetor Setup: Independent carburetion per cylinder provides precise throttle response and optimized fuel distribution across the RPM band.
Engine Protection Systems: Thermal sensors and oil-level alarms integrated with the CDI unit prevent overheating and mechanical seizure.
Heavy-Duty Gearcase: Reinforced lower unit housing, high-strength drive shafts, and enlarged bevel gears designed for continuous commercial loads.
