The stern drive can be damaged by impact, either
while trailering or boating. To minimize the
possibility of impact damage while trailering, keep
the stern drive raised to the trailering position.
The hydraulic system used to raise and lower the
stern drive can cushion impact and lessen damage
from head-on impacts to the stern drive from
underwater objects BUT ONLY when the boat is
moving forward. There is no protection if the
sterndrive is struck during revers operation or from
an angle when moving forward.
If you strike a submerged object, STOP THE
ENGINE as soon as possible and examine the stern
drive unit for damage. Even if no damage is visible,
there could be internal problems or difficulty
maneuvering. If you must use the boat after impact,
run at the lowest speed possible.

Engine failure away from shore can be
dangerous.
You must follow the recommended
maintenance schedule to best ensure trouble-free
operation of your engine and stern drive.

IBRATION
& C
AUSES
Some vibration is to be expected in your boat
because of the action of the engines and the
propeller. But excessive vibration indicates
conditions which must be promptly corrected to
avoid damage. The following are some conditions
which may cause vibrations.
•
Weeds, ropes, fishing lines, nets or your own
trailing lines can become wrapped around the
propeller and/or shaft, causing vibration and
loss of speed. Always stop the boat, make sure
it is clear to the rear, and then reverse the
propeller after going through a weedy area to
unwrap and clear away any weeds which may
have accumulated. If this doesn’t clear the
entanglement, and you can’t anchor or moor
the boat in shallow water to get to the stern drive
in the water, the boat will have to be taken out
of the water.
•
A badly damaged or distorted propeller or shaft
is an obvious cause of vibration. Run at slow
speed to shore. REPLACE IMMEDIATELY.
•
If the engine mounts fail and the engine can
contact the hull while it is running, vibration will
be felt. Run at slow speed to shore. REPLACE
IMMEDIATELY.
Do not allow obstructions to interfere with bilge
blower or ventilation intake operation. Engine
performance may be adversely affected.
!
WARNING
EXPLOSION/FIRE HAZARD – Run blower at least
four (4) minutes before starting engine or generator.
Check bilge and engine compartment for fumes.
