OIL SUPPLY PRIMING
Oil Hose Priming
Insert the oil supply hose from the oil tank into a
suitable container. Squeeze the oil primer bulb
until oil flows from the oil tank into the container.
Once oil supply hose from the oil tank is filled with
oil, connect the hose to the oil supply fitting on
outboard and secure with Oetiker clamp.
Oil Pump Priming
Squeeze the oil primer bulb until oil flows from the
oil supply hose, through the oil filter, and into the
crankcase oil pump (front oil pump).
IMPORTANT: Inspect oil filter to make sure it is
filled with oil. All air must be eliminated from the oil
filter during priming procedure.
Continue to squeeze the oil primer bulb until oil
flows through the front oil pump, into the oil distri-
bution hoses, and to the crankcase fittings.
Use Evinrude Diagnostics software to make sure
the EMM is programmed for the type of oil being
used.
250 – 300 HP (3.4 L) MODELS
Start the outboard. Use the oil priming functions in
the software to make sure the system is com-
pletely primed.
IMPORTANT: The outboard should be running
during the priming procedure to avoid pumping
too much oil into the crankcase, which could
cause a hard-starting condition.
Prime the rear oil pump FIRST (cylinder oil pump).
Use the Prime Cylinder Oiler button of the
Dynamic Test screen to prime the rear oil pump.
With the Prime Cylinder Oiler function activated,
continue to squeeze the oil primer bulb until oil
flows through the oil distribution hoses of the rear
oil pump.
The software priming function must
be used along with the primer bulb for two rea-
sons:
• The primer bulb alone will not move oil
through the rear pump assembly unless the
pump is running.
WARNING
Always use caution while working around
machinery with moving parts. The follow-
ing set-up procedures require running
tests that are performed with the out-
board’s motor cover removed.
