Technical tips
RiDE motor
The RiDE lever employs the same part used for the throttle lever that incorporates the APS. An RPS
(RiDE position sensor) is built into the RiDE lever.
The RiDE motor is an assembly part that includes the shift motor and trim motor, a shift position sensor
that detects the position of each motor, the trim position sensor, and a built-in SCU to control each mo-
tor.
This system has sensors, and also has a fail-safe function.
The ECM and SCU use CAN to deliver shift request, shift position, and trim position information.
Part name Function
1 RPS Detects the RiDE lever angle.
2 Electric trim switch Drives the trim motor.
3 Multifunction meter Displays information on shift position and trim position.
4 ECM
• Controls the engine operation based on signals transmitted
by each sensor and switch, and sends signals to SCU.
• Sends information on shift position and trim position to the
multifunction meter.
5 RiDE motor
An assembly that incorporates SCU, shift motor, SPS, trim mo-
tor, and trim position sensor.
6 SCU
Shift control: Transmits a shift position signal to the ECM and
drives the shift motor based on the shift request from the ECM.
Trim control: Controls the trim motor based on the signal from
the trim switch and sends trim position information to the ECM.
7 Shift motor Switches the reverse gate angle.
8 Shift position sensor
Detects the shift position based on the rotation angle of the
shift motor.
9 Trim motor Switches the angle of jet thrust nozzle.
10 Trim position sensor
Detects the trim position based on the rotation angle of the trim
motor.
