They are intended for usage in planing and water displacing vessels. Distinctive features: contactless vortex high-pressure pump in water cooling system; adaptation to operation in plant-filled water bodies; discharge of exhaust gases at idle speed is provided through the openings located below water level, in other conditions – through propeller boss; double damping of the driving torque; inlet manifold with horizontal separation of the flow of fuel mixture, leaf-type valves, five-channel loopback scavenging and the tuned exhaust tube.
