Adaptive Speed Control; Advanced Sound Control; Engine Synchronization (Multiple Engines) - Mercury Racing 500R Operation And Maintenance Manual

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.

Advanced Sound Control

Advanced sound control (ASC) is a standard feature on the 500R outboard.
• ASC allows the vessel operator to toggle between two modes of
operation: Stealth or Sport mode.
• The mode of operation can be selected with an accessory dash switch,
VesselView, or SmartCraft gauge; Off = Stealth mode, On = Sport mode.
• When Stealth mode is active, the engine noise levels are low (the typical
smooth sound of Verado FourStroke power).
• When Sport mode is active, the engine noise levels are higher (a
definitive audible indicator of the engine's power).
• Stealth mode is the default mode of operation. If the vessel does not have
a VesselView display, SmartCraft gauge, or accessory switch, the ASC
will remain in Stealth mode.
NOTE: Stealth or Sport modes do not affect the engine horsepower or the
running characteristics of the engine.
When the engine is started, ASC will remain in the mode that was selected at
the time when the engine was turned off.

Engine Synchronization (Multiple Engines)

Digital Throttle and Shift (DTS) engines have an automatic engine
synchronization feature that engages automatically at key‑up. Sync mode
monitors the position of both ERC levers. If both levers are within 10% of
one another, all engines synchronize to the starboard engine's RPM. The
SmartCraft system will automatically disengage sync at the last 10% of the
lever range to allow each engine the ability to reach the maximum available
RPM. Sync mode cannot engage until its minimum RPM is met.
