Starting A Warm Engine; Shifting; Engine Shut Down (Stopping); Starting The Engine After Stopped While In Gear - Mercury TDI 3.0L Owner's Operation And Maintenance Manual

Section 2 - On The Water
c. Check the engine and drive system for oil leakage. Specifically inspect the oil filter, oil lines, oil line connectors, and
oil pan.
d. Check for coolant leaks. Check the coolant hoses and connection pipes of the heat exchanger, fluid coolers,
aftercooler, water pump, and drain fittings for leaks.
4. Correct any problems found, or see your Mercury Diesel‑authorized repair facility if you are unable to determine the
problem.

Starting a Warm Engine

1. Run the engine compartment bilge blower for five minutes. Otherwise, open the engine hatch to air out the bilge before
attempting to start the engine.
2. Place the remote control handle in neutral.
3. Turn the key switch to the "RUN" position.
4. Turn the key switch to the "START" position and release the key when the engine starts. Ensure that the charge indicator
and oil pressure warning lamps turn off.
5. Ensure that all the instrumentation functions properly and indicates normal readings.

Shifting

Shifting into gear at engine speeds above idle will damage the gearcase. Shifting into gear when the engine is not running
can misalign the clutch, preventing proper shifting. Always shift the gearcase into gear when the engine is operating at idle. If
you must shift while the engine is not operating, rotate the propeller shaft in the appropriate direction during shifting.
1. Ensure that the remote control shift lever is in Neutral.
2. To shift the sterndrive, move the remote control shift lever with a firm, quick motion forward to shift to forward gear, or
backward to shift to reverse.
3. After shifting the sterndrive, advance the throttle to the desired setting.
IMPORTANT: Avoid stopping the engine if the sterndrive is in gear. If the engine does stop with the sterndrive in gear, see
the following procedure:
4. Push and pull repeatedly on the remote control handle until the handle returns to the neutral detent position. This may take
several tries if the power package was operating above idle RPM when the engine stopped.
5. After the handle returns to the neutral detent position, resume normal starting procedures.

Engine Shut Down (Stopping)

1. Place the remote control lever in neutral.
Immediately stopping the engine after high load operation can damage the turbocharger bearings. Idle the engine for several
minutes before shutdown.
2. Operate the engine at idle speed for several minutes to allow the turbocharger and engine to cool.
3. Turn key switch to the "OFF" position.

Starting the Engine After Stopped While in Gear

IMPORTANT: Avoid stopping the engine if the sterndrive is in gear. If the engine does stop with the sterndrive in gear, see the
following procedure:
1. Push and pull repeatedly on the remote control handle until the handle returns to the neutral detent 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 detent position, resume normal starting procedures.

Trailering the Boat

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