Chaparral 420 PREMIERE, Руководство владельца/оператора

Shifting between forward and reverse should be
done when idling. Shifting at higher engine speeds
can be uncomfortable for passengers and cause
unnecessary stress on the transmission or cause
the engine to stop. If you attempt to shift gear at an
excessive engine speed, a safety function cuts in
automatically and delays shifting until the engine
speed has fallen to 1500 rpm.
Always do a forward/reverse operation as follows:
1. Reduce engine speed to idle and let the boat
more or less lose way.
2. Move the control lever to neutral with a rapid,
distinct movement. Pause briefly.
3. Then move the control lever to reverse with a
rapid, distinct movement and increase engine
speed.
Important: It is important that all engines run
during reversing maneuvers to prevent water
from entering via the exhaust pipe into the sta-
tionary engine.
Note: The throttle must be in IDLE position and
gearshifts in NEUTRAL position before starting
the engine. See your engine manufacturer’s
owner’s manual for specific starting instructions.
Engine Synchronizer
Synchronizing Engine Speed
When driving with twin engines, both operating
economy and comfort will increase when the
engines operate at the same engine speed (rpm).
When the synchronization function is activated, the
engine speed (rpm) of the starboard engine is auto-
matically adjusted to that of the port engine. The
synchronization function is activated automatically if
the following conditions are met: 1. The engine
speed levers for both engines are in (approximately)
the same position; 2. The engine speed on both
engines exceeds 800 rpm.
Note: The synchronizer is disengaged as soon
as the conditions are no longer met.

Electronic Trim Tabs
The trim tabs on your Chaparral yacht are mounted on
the port and starboard transom below the water line.
The operator can control the trim tabs at the helm with
rocker switches. Pushing the switch activates the
electric system that moves its tab up or down.
The trim tabs are protected by a circuit breaker on
the control station breaker panel that must be ON to
use the trim tabs.
Push the top halves of BOTH rockers down in a
momentary burst to trim the bow of your boat down.
Do not hold the rockers down because this will
cause you to overtrim the boat and the bow will dig
3-11
WARNING: Never shift to reverse when the
boat is planing.
CAUTION: Acceleration at full throttle is not
recommended until after the engine “break-in
period.” This break-in period also coincides
with the engine’s 20-hour checkup.
WARNING: Maneuvering/Control Hazard -
Ensure continuous visibility of other boats,
swimmers, and obstacles during bow-up transi-
tion to planning.
