Freezing Temperature Operation
IMPORTANT: If boat is operated during periods of freezing
temperature, precautions must be taken to prevent freezing
damage to power package. Damage caused by freezing IS NOT
covered by MerCruiser Limited Warranty.
CA17
Drive Unit Impact Protection
The Power Trim hydraulic system is designed to provide impact
protection for drive unit. If a submerged object is struck while boat is
moving forward, the hydraulic system will cushion the kickup of drive
unit as it clears the object, reducing damage to unit. After drive unit
has cleared object, the hydraulic system allows drive unit to return
to original operating position, preventing loss of steering control and
engine overspeed.
Use extreme caution when operating in shallow water or where
underwater objects are known to be present. Use extreme care to
prevent striking submerged object while operating in REVERSE. No
impact protection is provided in REVERSE.
If drive unit should strike a submerged object, stop engine as soon
as possible and inspect drive unit for damage. If damage is present
or suspected, boat should be taken to an Authorized MerCruiser
Dealer for thorough inspection and necessary repair. Operating a
damaged drive unit could cause additional damage to other parts of
drive unit, or could affect control of boat. If continued running is
necessary, do so at greatly reduced speeds.
IMPORTANT: Impact protection system cannot be designed to
ensure total protection from impact damage under all
conditions.
CA408
Drain Plug and Bilge Pump
The engine compartment in your boat is a natural place for water to
collect. For this reason, boats are normally equipped with a drain
plug and/or a bilge pump. It is very important to check these items on
a regular basis to ensure that the water level does not rise to come
in contact with your power package. Components on your engine will
be damaged if submerged. Damage caused by submersion is not
covered by the MerCruiser Limited Warranty.
