Adjusting trolling speed

You can adjust the trolling speed randomly by
increasing or decreasing it approximately 50
r/min. When in the trolling speed setting
mode, the display switches to the normal dis-
play when the engine speed is increased
(within 3000 r/min) using the throttle. When
the throttle is closed, the display returns to the
trolling speed setting mode. For details, see
the attached operation manual.

TIP:
Trolling is affected by currents and other
G
operating conditions and may differ from
the actual engine speed.
The default engine idle speed is reset auto-
G
matically when the display is switched to
the normal display. The default engine idle
speed is also reset automatically when the
engine is turned off or when the engine
speed exceeds 3000 r/min.
When warming up a cold engine, the trolling
G
speed cannot be decreased below the
specified engine idle speed.
