Engine Shut Down (Stopping); Protecting People In The Water; While Boat Is In Operation; While The Boat Is Stationary - Mercury MerCruiser Diesel Inboard 2.8L Operation & Maintenance Manual

Section 2 - On the Water
Shifting into gear at engine speeds above idle will damage the transmission. Shift into gear only when the engine is operating
at idle.
Excessive engine RPM in trolling mode may overheat transmission fluid and damage the transmission or engine. Never
operate the engine above 1100 RPM when the trolling mode feature is engaged.
Refer to the appropriate Technodrive operating manual for trolling valve operation instructions.
To prevent serious transmission damage, never operate the engine above 1100 RPM while in trolling mode.

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 the key switch to the "OFF" position or press the start‑stop switch button if equipped.

Protecting People in the Water

While Boat is in Operation

People in the water cannot take quick action to avoid a boat heading in their direction.
Approach slowly and exercise extreme caution when boating in areas where people may be in the water.
When a boat is moving and the gear shift is in neutral, there is sufficient force by the water on the propeller to cause the
propeller to rotate. This neutral propeller rotation can cause serious injury.

While the Boat is Stationary

A spinning propeller, a moving boat, or any solid device attached to the boat can cause serious injury or death to swimmers.
Stop the engine immediately whenever anyone in the water is near your boat.
Shift into neutral and shut down the engine before allowing people in the water near the boat.
High‑Speed and High‑Performance
If your boat is considered a high‑speed or high‑performance boat, we recommend that you never operate it at its high‑speed
capability without first requesting an initial orientation and demonstration ride with your dealer or an operator experienced with
your boat. For additional information, refer to the Hi‑Performance Boat Operation booklet from your Mercury Diesel
authorized repair facility.

Passenger Safety In Pontoon Boats and Deck Boats

Whenever the boat is in motion, observe the location of all passengers. Do not allow any passengers to stand or use seats
other than those designated for traveling faster than idle speed. A sudden reduction in boat speed, such as plunging into a
large wave or wake, a sudden throttle reduction, or a sharp change of boat direction, could throw them over the front of boat.
Falling over the front of the boat between the two pontoons will position them to be run over.

Boats Having An Open Front Deck

No one should ever be on the deck in front of the rail while the boat is in motion. Keep all passengers behind the front rail or
enclosure.
