NEUTRAL THROTTLE WARMUP (NTW):
NTW allows you to control engine throttle without gear
engagement, so that you can warm up your engines
at a higher RPM. A slow flashing green neutral
indicator lamp tells you that NTW is engaged for the
corresponding engine.
To engage Neutral Throttle Warmup:
• Move the engine’s control lever to the Neutral
position. The neutral indicator lamp will light
steady green.
• Press the corresponding N button. The neutral
indicator lamp will flash green to indicate that NTW
is engaged.
• You can now increase throttle and the engine will
stay in neutral.
To disengage Neutral Throttle Warmup:
• Return the engine’s lever to the Neutral position.
• Press the corresponding N button. The lamp will
light steady green. The engine and transmission
will now respond normally to lever commands.
TROLLING MODE (TM):
• Provides greater throttle sensitivity: moving an engine’s control
lever to full forward will only produce a percentage of wide open
throttle. The default TM throttle limit is 50% in forward gear, 100%
in reverse gear.
• Very slow flashing (one second on, two seconds off) green neutral
indicator lamps indicate that trolling mode is engaged.
TO ENGAGE Trolling Mode:
• Move one or both control levers to the forward idle or reverse idle
positions. The other lever must be in the same position or in neutral.
• Press either N button. Both lamps will flash green slowly to indicate
that TM is engaged.
TO DISENGAGE Trolling Mode:
• Move both control levers to forward idle, reverse idle, or neutral
position.
• Press either N button. The flashing green lamps will go out to
indicate that TM is disengaged.
