c. iMpacT To sTern Drive
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 stern
drive is struck during reverse 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 difculty
maneuvering. If you must use the boat after impact,
run at the lowest speed possible.
