Mercury Avator 7.5e Operation, Maintenance And Installation Manual page 18

Reduce speed and proceed with caution when driving a boat in shallow water
areas or in areas where suspected underwater obstacles may exist that could
be struck by the outboard or the boat bottom. The most significant action the
operator can take to help reduce injury or impact damage from striking
a floating or underwater object is to control the boat speed. Under these
conditions, boat speed should be kept 1.5 to 8 km/h (1 to 5 mph).
Avoid serious injury or death from all or part of an outboard or drive unit
coming into the boat after striking a floating or underwater object. When
operating in waters where objects may be at the surface or just under the
surface of the water, reduce your speed and keep a vigilant lookout.
Examples of objects that can cause outboard damage are dredging pipes,
bridge supports, wing dams, trees, stumps, and rocks.
Striking a floating or underwater object could result in any of an infinite number
of situations. Some of these situations could yield the following:
• Part of the outboard or the entire outboard could break loose and fly into
the boat.
• The boat could move suddenly in a new direction. A sharp change in
direction can cause occupants to be thrown out of their seats or out of the
boat.
• The boat's speed could rapidly reduce. This will cause occupants to be
thrown forward or even out of the boat.
• The outboard or boat could sustain impact damage.
After striking a submerged object, stop and power down the outboard as soon
as possible and inspect it for any broken or loose parts. Further, if damage
is present or suspected, power down the outboard, remove or disconnect the
battery and do not continue to use the outboard. The outboard should be taken
to an authorized dealer for a thorough inspection and necessary repair.
The boat should also be checked for any hull fractures, transom fractures, or
water leaks. If water leaks are discovered after an impact, immediately activate
the bilge pump.
