Steering
Your Pro-line is equipped with a self contained hydraulic steering system. When the steering wheel
is turned the helm pump pumps fluid to the steering cylinder, causing the boat to turn. Stern drive
27's use a rack and cable helm unit.
Periodically check the fluid level and fill if necessary. Beware of adding to much fluid especially if
the ambient temperature is cold because subsequent expansion could cause leaking or damage to
your system (refer to manual in packet). Every 24 hours of operation check all nuts, caps, and hose
fittings for tightness. Check that the hoses are not chafing, or kinking on sharp corners. Also check
that hose ends are not damaged or distorted by the clamps.
The fluid should be changed yearly under normal conditions, twice yearly for heavy use. Lubricate
and maintain in accordance with manufactures manual.
If your steering does not operate properly first check for; drive entanglements, fluid level, hoses /
fittings for leaks, and / or air in the system.
Instruments
Your Pro-Line's instrumentation will vary from model to model and engine to engine, therefore the
following descriptions are general; refer to your engine manual for specifics.
Fuel Gauge
Differences in temperature, loading, speed and trim will affect the actual accuracy of this gauge in
service. It is important to verify the fuel flow in gal./hr. for your boat and make note of your gauge
position with respect to time for different RPM settings. No gauge can give 100% accuracy. If you
notice unusually high or low fuel consumption, investigate to see if the engine is using more fuel
than normal.
Oil Pressure (I/O only)
This is a very important instrument, oil pressure is vital to engine life. Generally readings of 10-15
psi at idle and 15 to 25 psi at cruise are sufficient to protect your engine. If you notice abnormally
low or high readings; check and correct oil level, if condition persists consult your dealer. If you
lose oil pressure; shut down the engine immediately. Find and correct the problem before restarting
engine. Running your engine without oil pressure will result in serious and costly damage.
Water Temperature
The water temperature gauge indicates the internal water temperature of your engine. Your engine
is equipped with a thermostat to quickly bring the engine up to its optimum operating temperature
range of 150 to 170 degrees f. All outboard engines are also equipped with an audio alarm system
indicating an overheat condition. If the gauge or alarm indicates an overheat condition,
immediately shut the engine off, lift the drive and inspect water intakes for obstructions such as
aquatic vegetation or mud. After finding the source of the overheating, restart engine and confirm
water flow, if water does not flow within five seconds shut the engine off.
