INFO
Reverse with traction control
The reverse with traction control is activated when the shift lever is in the reverse position and the
reverse sensor operates. The reverse with traction control limits the engine speed to 3,000 r/min so
that an efficient water flow is produced when the watercraft is operating in reverse. The reverse with
traction control is deactivated when the shift lever is returned to the forward position. The no-wake
mode cannot be activated when the reverse with traction control is activated.
Idle speed control
The ETV maintains a steady engine idle speed under various operating conditions.
Over revolution control
L-MODE (low-rpm mode) control
• In the L-MODE, the ETV regulates the opening angle of the throttle valve and controls ignition tim-
ing.
• Maximum engine speed is limited to approximately 5,400 r/min.
Slant detection control
The slant detection control is activated under the following conditions.
• If the engine speed is below 3,000 r/min.
• If the slant detection switch is on.
If the slant detection control is activated, ignition and fuel injection are cut to all cylinders and the
engine is turned off.
If the slant detection control is activated, no indication is made on the multifunction meter.
The slant detection control is not deactivated until the engine is turned off.
