Freezing Temperature And Cold Weather Operation
IMPORTANT: If boat is operated during periods of freezing temperature, precautions must be taken to
prevent freezing damage to the sterndrive. Refer to “Cold Weather or Extended Storage” for related in-
formation and draining instructions.

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 kick-up 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 over speed.
Use extreme caution when operating in shallow water or where underwater objects are known to be present.
Use extreme care to prevent striking submerged objects 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 inspec-
tion 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 dam-
age 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.
CA19
Trailering Boat
Boat can be trailered with drive unit in up or down position. Adequate road clearance is required between road
and gear housing skeg when trailering with drive unit in down position.
If adequate road clearance is a problem, place drive unit in full trailer position and support with an optional trailer
kit which is available from your Authorized MerCruiser Dealer.
