Starting the Engine After It Has Been Stopped While In Gear

IMPORTANT: Avoid stopping the engine if the sterndrive unit is in gear. If the engine does stop, refer to the following
procedure:
1.
Push and pull repeatedly on the remote control handle until handle returns to the neutral/idle position. This may take
several tries if the power package was operating above idle RPM when the engine stopped.
2.
After the handle returns to the neutral/idle position, resume normal starting procedures.

Throttle Only Operation

1.
Refer to Remote Controls section for remote control features.
2.
Move the control lever to the idle/neutral position.
3.
Depress and hold the throttle only button, and move the control lever to the idle/forward or idle/reverse position.
4.
Advancing the control lever beyond the idle/forward or idle/reverse position will cause engine speed to increase.
IMPORTANT: Moving the control lever back to the idle/neutral position will disengage the throttle only button and allow the
engine to shift into gear.
5.
Throttle only mode is deactivated by moving the control lever to the idle/neutral position. Moving the control lever from the
idle/neutral position to the idle/forward or idle/reverse position without pressing the throttle only button will shift the unit into
the chosen gear.

Trailering the Boat

Your boat can be trailered with the sterndrive unit in the up or down position. Adequate clearance is required between the road
and sterndrive when transporting.
If adequate road clearance is a problem, place the sterndrive unit in full trailer position and support it with an optional trailer kit
which is available from your authorized Mercury MerCruiser dealer.

Freezing Temperature Operation

IMPORTANT: If the boat is operated during periods of freezing temperature, precautions must be taken to prevent freeze
damage to the power package. Damage caused by freezing is not covered by Mercury MerCruiser Limited Warranty.

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 come into contact with your power package. Components on your engine will be damaged if submerged. Damage caused
by submersion is not covered by the Mercury MerCruiser Limited Warranty.
