SUZUKI DUAL LOUVER SYSTEM - The DF350A/DF325A/DF300B is equipped with dual louver at the air intake to remove water from the air taken into the cowl. Incorporating a direct intake system makes the highest compression ratio of 12.0:1 (DF350A),10.5:1(DF325A/DF300B) possible, ultimately leading to a higher engine output.
DUAL WATER INLET - The engine’s cooling system relies on water supplied through low water intakes located on the lower unit. This dual water inlet configuration increases water flow into the lower unit, delivering greater cooling efficiency. Positioning the forward inlet by the gear case nose delivers a greater water supply, especially at high speeds. The second inlet is positioned lower, allowing the DF350A/DF325A/DF300B to operate in shallow water.
DUAL INJECTOR - Dual injectors deliver just the right amount of fuel at just the right time into the cylinder. This dual injector contributes to higher output and better fuel efficiency.
