GENERAL INFORMATION
21
Keep in mind, the most important thing you can do to help reduce
injury or impact damage during an impact is control the boat speed.
Boat speed should be kept to a minimum planing speed when
driving in waters known to have underwater obstacles.
After striking a submerged object, stop the engine as soon as
possible and inspect it for any broken or loose parts. If damage is
present or suspected, 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.
Operating a damaged outboard could cause additional damage to
other parts of the outboard, or could affect control of the boat. If
continued running is necessary, do so at greatly reduced speeds.
!
WARNING
Operating a boat or engine with impact damage can result in
product damage, serious injury, or death. If the vessel
experiences any form of impact, have an authorized Mercury
Marine dealer inspect and repair the vessel or power package.
Exhaust Emissions
BE ALERT TO CARBON MONOXIDE POISONING
Carbon monoxide is present in the exhaust fumes of all internal
combustion engines. This includes the outboards, sterndrives and
inboard engines that propel boats, as well as the generators that
power various boat accessories. Carbon monoxide is a deadly gas
that is odorless, colorless and tasteless.
Early symptoms of carbon monoxide poisoning which should not
be confused with seasickness or intoxication, include headache,
dizziness, drowsiness, and nausea.
!
WARNING
Carbon monoxide poisoning can lead to unconsciousness, brain
damage, or death. Keep the boat well ventilated while at rest or
underway and avoid prolonged exposure to carbon monoxide.
