OIL SUPPLY PRIMING
250 – 300 HP 90° V6 (3.4 L) Models
Oil Hose Priming
Insert the oil supply hose from the oil tank into a
suitable co ntainer. Squeeze the oil primer bu lb
until oil flows from the oil tank into the container.
Once oil supply hose from the oil tank is filled with
oil, conne ct t he ho se to the oil su pply fit ting 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 f ilter, 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 sq ueeze 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 m ake sure
the EMM is pro grammed for the type of oil being
used.
Start the outboard. Use the oil priming functions in
the sof tware to mak e sure the s ystem is co m-
pletely primed.
IMPORTANT: The outb oard sh ould be running
during t he primin g procedure t o avo id pu mping
too much oil into the crankcase, which cou ld
cause a hard-starting condition.
Prime the rear oil pump FIRST (cylinder oil pump).
Use the Prime Cylinder Oiler button o f th e
Dynamic Test screen to prime the rear oil pump.
With the Prime Cylinde r Oiler function activate d,
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.
• The pump assembly cannot prime itself until
it has been filled with oil.
A 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.
