OILING SYSTEM TESTS

Static Test
Remove oil distribution hose from fitting at crank-
case. Squeeze oil supply primer bulb to provide oil
to injection pump.
Use the oil injector test of the Evinrude Diagnos-
tics Software program 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
Confirm that the oil injection fittings of the cylinder
and crankcase assembly allow fluid to move.
Remove oil distribution hose from fitting. Connect
1/8 in. I.D. (3 mm) clear vinyl tubing to the fitting.
Use a syringe filled with isopropyl alcohol to force
fluid through the fitting.
LOW OIL Sending Unit Test
Remove the oil from the oil tank, and turn the key
switch ON. The LOW OIL light/warning of the Sys-
temCheck gauge should activate. Once the warn-
ing has been verified, turn the key switch ON and
refill the oil tank. Confirm that the LOW OIL warn-
ing stops as the oil level exceeds one-quarter of
oil tank’s capacity.
