2.5.2 Single Lever Remote Control
Handle
This remote control system uses a single-
handle to operate the marine gear-clutch
(neutral, forward, reverse) and to control
the engine speed.
NEUTRAL: Power to the propeller shaft is
cut off and the engine idles.
The handle controls the direction of the
boat (ahead or astern) and, at the same
time, acts as an accelerator increasing the
engine speed as it is pushed further in the
FWD or REV direction. If the handle is
pulled out, engine speed can be controlled
without engaging the clutch (clutch re-
mains in the NEUTRAL, no load position).
Yanmar recommends the use of a sin-
gle-lever type for the remote control
system. If only the two-lever type is
available in the market, operate the en-
gine at 1000 rpm or lower before engag-
ing and disengaging the marine
gear-clutch.
