Engine Operation - Quicksilver 810 Arvor Owner's Manual

Quicksilver 810 Arvor — System & Component Overview and Operation

13. Engine Operation

Your boat is powered by a Mercury 2.8L closed cooled diesel engine with a transmission connected to
a straight drive shaft. Prior to operation of the vessel, the following will need to be observed:
Engine Cooling System
Make sure that engine cooling water is flowing throughout the system. On the port side of the engine
compartment, there is an external water pickup for cooling the engine. Prior to starting the engine,
make sure that the seacock is opened and water is throughout the system. FAILURE TO DO THIS WILL
CAUSE DAMAGE TO THE ENGINE.
Check the system to make sure that the seawater strainer is clear and free of any debris. To clean the
seawater strainer:
1. Close the seacock so that no water will enter the engine.
2. On the top of the strainer, rotate the clear top counter-clockwise.
3. Remove the basket and debris in the strainer. Flush the basket and strainer with clean water.
4. Re-install the strainer element and grease the O-rings.
5. Secure the lid. Never use tools for tightening the lid.
6. Check to make sure that the lid is installed properly. An improperly sealed lid will result in air
being sucked in by the seawater pump, and could result in overheating the engine.
Shaft Cooling System
In addition, there is a water pickup connected to the shaft stuffing gland. Prior to starting the engine,
make sure that the seacock is opened. FAILURE TO DO THIS WILL CAUSE DAMAGE TO THE SHAFT
SEAL.
Engine
Make sure that the engine cooling system seacock is OPEN
before starting the engines. Keep the engine cooling
seacock OPEN while the engine is running.
