Reverse thrust
The outboard motor has a structure that discharges the exhaust gas from above the anti-cavitation
plate when the remote control lever is in the R position and the engine speed is 2000 r/min or less. As
a result, propeller cavitation can be prevented when the outboard motor is operating in reverse. In ad-
dition, thrust when operating in reverse is increased, stopping performance is increased, and vibration
and noise are lower. For boats that are equipped with Helm Master, performance when moving side-
ways is increased.
