6-6 Indmar Marine Engines
Pull the dipstick with the yellow handle from the reser-
voir, and clean it with a lint-free cloth. Then push it back
in all the way until it stops. Remove it again, keeping the
tip down, and note the oil level on the crosshatched
area. An oil level within the crosshatched area is normal.
If the level is below the crosshatched area, add 1 quart
(0.96 L) of 5W30 Mobil 1 synthetic oil through the black
oil reservoir fill cap and take another reading.
Do not overfill the reservoir, as this may
result in excessive oil consumption. Oil lev-
els above the crosshatched area may
degrade lubrication system performance. In
the event of an over filling, some oil will be
discharged through the dry sump tank vent
and wet the flame arrestor and front of the
motor.
Oil Change Procedure
NOTICE
Indmar strongly recommends that you take your boat
to your authorized dealer to perform this critical serv-
ice.
Materials Required:
8 quarts 5W30 Mobil 1 Synthetic Oil
Pennzoil PZ52 Oil Filter
Oil Change Pump/Oil Suction Device
The oil change interval for the LS7 is the same as any
other Indmar engine. The first oil and filter change should
be done after approximately 10 hours of operation.
Subsequent oil changes should be done every 50 hours
or annually, whichever comes first.
To remove the oil from the engine requires accessing
two oil drain locations. If you have an early model that
only has one oil drain hose, remove the cap from the oil
drain hose and either drain or pump the oil from the oil
pan through the hose. The hose is connected to the oil
pan where approximately 1 quart of oil will be retained.
Once the residual oil has been removed from the oil pan,
reinstall the drain cap and secure the hose.
Next, remove the fill cap from the oil tank. You will need
to use a pump or oil suction device to remove the oil
from the tank. Just run the pump or suction line all the
way to the bottom of the tank and remove all of the oil.
If the engine you are changing the oil on has two oil
drain hoses, you must drain or pump the oil from the oil
pan (as above) from one of the hoses. The other hose is
connected to a different fitting on the front of the oil pan
that will drain oil tank.
