Technical tips
Shift control
The reverse gate on RiDE models is in the F position when the engine is stopped. When the engine is
started, the reverse gate returns to the N position automatically.
The ECM calculates the throttle lever opening angle and RiDE lever opening angle to control shifting.
Engine speed and reverse gate positions are also controlled. This control function automatically adjusts
the engine speed, even while the throttle lever is being held in position, preventing sudden acceleration
or sudden shift changes. The shift control is also equipped with a learning function that automatically
corrects the shift position. The learning function corrects the shift position through being connected to
the YDIS from an early stage, moving the reverse gate from the F position to the R position in order to
find an optimum shift position.
