1. For Your Safety
1.1 Safety Precautions For Inspection
Battery
Never smoke or permit sparks near the battery, because it may emit ex-
plosive hydrogen gas. Place the battery in a well-ventilated place.
Fuel
Use only diesel fuel. Never use other fuels, including gasoline, kero-
sene, etc., because they could cause a fire. The wrong fuel could also
cause the fuel injection pump and injector to fail due to lack of proper
lubrication. Be sure to check that you have selected the correct diesel
fuel before filling the fuel tank.
Do not use starting fluids or sprays. Their use may cause explosion, se-
rious injury and engine damage.
Fire Prevention
Be sure to stop the engine and confirm that there are no open flames in
the vicinity before fueling. If you do spill fuel, wipe such spillage careful-
ly and dispose of the wiping materials properly. Wash your hands thor-
oughly with soap and water.
Never place oil or other flammable material in the engine room.
Install a fire extinguisher near the engine room, and familiarize yourself
with its use.
Exhaust Gas
Exhaust gas contains poisonous carbon monoxide and should not be
inhaled.
Be sure to install ventilation ports or ventilators in the engine room and
ensure good ventilation during engine operation.
Moving Parts
Do not touch or let your clothing get caught in the moving parts of the
engine, such as the front drive shaft, V-belt or propeller shaft, during en-
gine operation. You will be injured.
Never operate the engine without covers on the moving parts.

EN
Burns
The whole engine is hot during operation and immediately after
shut-down. The exhaust manifold, exhaust pipe and high pressure fuel
lines are very hot. Never touch these parts with your body or clothing.
Alcohol
Never operate the engine while you are under the influence of alcohol.
Never operate the engine when you are ill or not feeling well.
Battery Fluid
Battery fluid is dilute sulphuric acid. It can blind you if it gets in your
eyes, or burn your skin. Keep the fluid away from your body.
If you touch it, wash it off immediately with a large quantity of fresh wa-
ter and call your doctor for treatment.
Fire by Electric Short-Circuits
Always turn off the battery switch before inspecting the electrical sys-
tem.
Failure to do so could cause short-circuiting and fires.
Stop the engine before you service it.
Turn the battery switch off. If you must inspect while the engine is in op-
eration, never touch moving parts. Keep your body and clothing well
clear of all moving parts.
Scalds
When extracting oil from the engine while it is still hot, don't let the oil
splash on you.
Wait until the temperature has dropped before extracting cooling water
from the engine. Don't let it splash on you.

3. Selecting Lubricating Oil
EN
3. Selecting Lubricating Oil
3.1 Choice of lube oil
The choice of lube oil is very important to
a Sail-Drive. If an unsuitable oil is used, or
oil change is neglected, it may result in
damage, and a shorter Sail-Drive life.
When selecting the lube oil, it must be one
of the following:
3.2 Kind of lube oil
Use only oil of quality “GL-4" or "GL-5" in
the API service, and SAE No. 90 or
80W90.
(Except model SD20 x 1GM10C and
SD50/-4T)
Use only oil of quality "cc" or greater in the
API service, and SAE no. 10W30.
(Applicable model: SD20 x 1GM10C)
For SD20 (except if coupled with the 1GM10C) and SD50/-4T
Use "Quicksilver High Performance Gear
Lube" for the SD50/-4T.
This lube oil is available through all Mer-
Cruiser, Mercury, Mariner and Force out-
lets in their Quicksilver accessories
program.
