HYDRAULIC STEERING
Hydraulic steering systems require regular preventative mainte-
nance for continued safe and reliable operation. The oil level in the
helm pump must be maintained within acceptable operating levels.
A low oil level will cause air to be introduced into the steering sys-
tem and result in unresponsive steering. The oil level should al-
ways be within 1/2 inch from the base of the fill hole located on the
front top portion of the helm pump. Check the entire steering sys-
tem regularly for oil leaks. Unobserved leaks over a period of time
will result in unresponsive steering or loss of steering. Any moving
mechanical linkages, sliders, etc. should be greased as needed
with high quality marine grease approved by the steering manufac-
turer. Refer to the manufacturer’s steering manual for specific rec-
ommendations and additional maintenance. Any slow or sudden
change in the “feel” of your steering system indicates an immediate
need for a thorough inspection. All repairs and replacements to
steering systems should be made by an authorized dealership.
TRIM TABS
Sea Hunt Boats installs Lenco trim tabs. The tab planes
mounted on the transom of the boat are actuated by a electric ram
piston. Two switches at the helm operate the trim tabs. The
switches are labeled "bow up-bow down" and correspond to the
side of the boat the switch is closest to, although the tab on the op-
posite side of the boat causes this motion. Always remember to fully
retract the trim tabs prior to putting the boat on a trailer. Stepping
on the trim tab plane may cause damage to the unit or result in in-
jury. See your Lenco owner’s manual for complete maintenance
information.

TACHOMETER
The Tachometer
indicates the engine
RPM (Revolutions
Per Minute). Consult
your engine owner’s
manual for the rec-
ommended operat-
ing RPM range.
Proper engine operating range may vary between 2-Stroke and 4-
stroke engines. If your boat does not reach the maximum RPM rec-
ommended for your engine(s), a change in propeller may be neces-
sary.
SPEEDOMETER
The Speedometer indicates your boat speed. The speedometer
can display speed in two units of measurement: MPH (miles per
hour), or KNOTS ( 1 Knot = 1 nautical mph, or 1.15 statute mph).
FUEL GAUGE
The fuel gauge indicates the fuel level. When checking fuel level
the attitude of your boat in the water can impact the reading.
USABLE FUEL
The fuel pickup tube inside the gas tank is not capable of with-
drawing all of the fuel from the tank. For this reason, never operate
your boat at extremely low fuel levels.
TRIM GAUGE
The Trim Gauge displays the degree of tilt/trim angle of the out-
board engine.
