Adaptive Speed Control
This outboard package utilizes adaptive speed control which automatically
adjusts the engine load (throttle) to maintain engine speed (RPM). For
example, when the boat operator steers into a hard turn, which results in
increased load on the engine and a loss of RPM, the propulsion control module
(PCM) will open the throttle to maintain RPM through the turn, without the need
for the operator to increase the remote control throttle handle. Another example
is when cruising or utilizing the boat for tow sports, engine speed will remain
constant, regardless of load changes due to waves, trim position, turning or
load changes from tow sports. Adaptive speed control is active from idle RPM
up to max rated RPM, however, can only maintain engine speed when the
throttle is less than wide open.
