Oil Injection Pump Function Test; Oil Injection Fittings Flow Test; Low Oil Sending Unit Test - BRP E250DHLSCS Service Manual

Attach a vacuum tester to the outboard side of oil
supply hose and draw 7 in. Hg (24 kPa) vacuum
on the hose for at least five minutes. Repair or
replace any leaking components. Reinstall the oil
hose.

Remove oil distribution hose from fitting at crank-
case. Squeeze oil supply primer bulb to provide oil
to injection pump.

OILING SYSTEM TESTS
Running Test
Start the outboard and observe oil flow. Confirm
that a small amount of oil is discharged while
injection pump is activated.
Static Test
Use the Evinrude Diagnostics software oil injector
test to activate injector. Confirm that a small
amount of oil is discharged while injection pump is
activated.
Results:
Oil flows from distribution hose, compare to oil
•
flow at other distribution hoses.
No oil discharge, compare to oil flow at other
•
distribution hoses. If one or more hoses fail to
discharge oil, check for a kinked or restricted
hose before replacing the oil injection pump
assembly.

Oil Injection Fittings Flow Test

Make sure the oil injection fittings of the cylinder
and crankcase assembly allow fluid to move.
Remove oil distribution hose from crankcase fit-
ting. Temporarily install a length of oil hose.on the
fitting.
Use a Syringe, P/N 346936, filled with isopropyl
alcohol to force fluid through hose and fitting.

LOW OIL Sending Unit Test

Remove oil from the oil tank
Turn the key switch ON. The dash mounted
Engine Monitor system should show a LOW OIL
warning.
Once the warning has been confirmed, refill the oil
tank. The LOW OIL warning should stop when the
oil level exceeds one-quarter of oil tank's capacity.
