IMPACT DAMAGE
If you hit any object, stop immediately and examine
the engine for loosening of attaching hardware and
clamp screws, if equipped. Inspect for damage to
swivel and stern brackets, steering components,
and components in the area of impact. Also, exam-
ine the boat for structural damage. Tighten any
loosened hardware. If the collision occurred in the
water, proceed slowly to harbor. Before boating
again, have your DEALER thoroughly inspect all
components.
Your engine has a shock absorption system de-
signed to help withstand damage from impact with
underwater objects at low to moderate speeds.
However, high speed impacts with rigid underwater
objects like pilings or boulders can be beyond the
capability of the absorption system. Such impacts
can result in serious damage to your engine and in-
jury to boat occupants from the engine or its parts
entering the boat. Occupants can also be ejected or
injured by falling against portions of the boat as a
result of rapid deceleration following impacts. When
boating in unfamiliar, shallow or debris-laden wa-
ters, seek information on safe boating areas and
navigation hazards from a reliable local source. Re-
duce your speed and keep a sharp lookout!
WARNING
Failure to inspect for damage could result in
sudden, unexpected component failure,
loss of boat control, and personal injury.
Unrepaired damage could reduce your boat
and engine’s ability to resist future impacts.
LOW OIL PRESSURE WARNING
Should crankcase oil pressure drop to a danger-
ously low level during engine operation, the low oil
pressure warning will activate and the engine
speed will not exceed 2000 RPM (FAST idle).
If, during operation, your engine slows itself to fast
idle and will not exceed that pace, shut OFF the en-
gine.
If tilted, place the engine in vertical position.
Check the oil level on the dipstick and add oil, if
needed. Refer to Crankcase Oil and Filter and
Engine Specifications.
Examine the oil fill cap and drain screw for evidence
of oil leakage and make sure they are tight.
The engine’s shock absorption system does not
work while operating in reverse. If you back into an
object, either in the water or while trailering, your
boat and engine can be seriously damaged.
If the dipstick shows the oil level is okay, leave the
engine upright and shut off for ten minutes, then
start it. If the engine still limits itself to about 2000
RPM, see your DEALER.
Reset — After oil pressure has been restored, op-
erate the engine below 1500 RPM to reset the
warning system for normal operation.
If the oil level is correct, see your DEALER.
IMPORTANT: Do not rely on the low oil pressure
warning to indicate the need to add oil. Be sure to
periodically check the engine oil level. If the oil level
is low, severe engine damage can result.
