Trim Tab Maintenance; Tachometer - Four winns FREEDOM Owner's Manual

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.
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. Al-
ways keep the fluid level between the designated marks
on the trim tab pump-reservoir. Refer to the manufactur-
ers information for specifications on the type of fluid to
be used and other operation and maintenance infor-
mation.
E - 7 INSTRUMENTATION
The helm station on Freedom™/Horizon™ models are
equipped with a complete set of individual engine instru-
ment gauges. These instrument gauges allow the boat
operator to constantly monitor the operational condition
of the engine. Close observation of these instrument
gauges could save the engine from damage. See Fig-
ures E3 & E4 for examples of helm layouts.

A. Tachometer
The tachometer indicates the speed of the engine in revo-
lutions 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. Note: Some models come with a tachometer/
hour meter combination gauge which allows for hour meter
viewing at the helm. Please refer to Section E-7K - En-
gine Hour Meter for information regarding the engine hour
meter.
NOTICE
Never exceed the maximum recommended
operating rpm of your engine. Maintaining maxi-
mum, or close to maximum rpm for extended
periods can reduce the life of the engine.
Some engines are equipped with devices that limit engine
rpm in accordance with the oil pressure, or engine tem-
perature. Refer to the engine manual included in the owner'
packet for additional information.
The tachometer must be set for different engines installed.
This is typically done at the factory. The tachometer
gauge is shown along with the table detailing the tachom-
eter settings. See Figure E5.
