Morse Controls. Each handle is a
combined transmission shift lever
and throttle.
4J3: Engine Controls
Hele Mai
is fitted with
Morse electronic
engine controls for
throttle and shift. They have the following advantages: (1) they are very
easy to operate, with no “drag”; and (2) they are trouble-free.
Operation:
To turn on the controls:
Turn on the “Electronic Engine
Controls” breakers.
To activate a control station:
Open the cover on either control
head between the control levers and press the “Select” switch.
This activates this control station, and the green “Neutral” lamp
will illuminate.
To shift and accelerate engines normally:
Moving either/both
levers out of their mid-range forward will engine forward ger,
then moving them further will accelerate that engine above idle.
The orange “Forward” or “Reverse” lamps will illuminate.
To fast-idle an engine:
While the control is in neutral with the engine idling
,
press and
hold the select button while moving the control lever forward
.
The green “Neutral”
lamp will flash, indicating the engine is in neutral in the “fast-Idle” mode.
WARNING: Because it takes little effort to move these controls, and
therefore it is easy to apply more throttle than intended especially
when maneuvering in the harbor, use your fingertips for throttle
operation! Use caution until habituated to their sensitivity.
