cause substan tial stee ring and handling difficul ties. Be
extremely careful when running in a following sea. The
effect of trim tabs is ampli fied under such condi tions.
Steer ing and handling difficulties can result from im-
proper trim tab usage, especially in a following sea. If
unsure of proper trim tab positioning, raise the trim tabs
to the full-up position.
NOTICE
Never exceed the maximum recommended
operating RPM of your engine. Maintaining
maximum, or close to maximum RPM for
extended periods can reduce the life of the
engine(s).
Some engines are equipped with devices that limit
engine RPM in accordance with the oil pressure,
or engine temperature. Refer to the engine manual
included in the owner’ packet for additional informa-
tion.
When running at high engine speeds, be sure
the trim tabs are in the full up position. Trim tab
action should be only enough to compensate
for any listing. Trim tab adjustments at high
speeds are extremely critical. Be prepared to
slow down should handling difficulties arise.
The tachometer must be set for different engines
installed. This is typically done at the factory. The
tach-ometer gauge is shown along with the table
detailing the tachometer settings. See Figure E4.
When running in a displacement (very slow speed)
mode, better efficiency will be obtained with the trim
tabs in the full-up position.
C. Trim Tab Maintenance
Check the fluid level of the trim tab reservoir often.
Always keep the fluid level between the designat ed
marks on the trim tab pump-reservoir. Refer to the
manufacturers information for specifi cations on the type
of fluid to be used and other operation and mainte-
nance information.

INSTRUMENTATION
The helm stations on Four Winns models are
®
equipped with a complete set of individual engine
instrument gauges. These instrument gauges allow
the boat operator to constantly monitor the operational
condition of the engine. Close observation of these in-
strument gauges could save the engine from damage.
A. Tachometer/Hour Meter Combination Gauge
The tachometer indicates the speed of the engine in
revolutions per minute (RPM). This speed is not the
boat speed or necessarily the speed of the propeller.
The tachometer may not register zero with the ignition
key in the OFF position.
Figure E4: Tachometer Settings
The tachometer/hour meter combination gauge
allows for hour meter viewing at the helm. See Figure
E5. The hour meter provides a numeric record of
elapsed engine operating time. This information is
important in determining scheduled maintenance
intervals, ship’s log data, cruise information, etc.
