Components; Oil Tank Assembly; Service Codes - Evinrude E-tec 75 HP Service Manual

COMPONENTS

The oiling system consists of the following compo-
nents:
•
Oil tank and injection pump and manifold
assembly (includes distribution manifold and
pressure switch)
•
Oil pressure switch
•
SystemCheck LOW and NO OIL warning sig-
nals
•
Cylinder and crankcase
•
Oil recirculation system

Oil Tank Assembly

The oil tank is powerhead mounted and should be
properly monitored for oil level and condition. The
oil injection pump and manifold assembly distrib-
utes the oil supplied by the oil injection pump. A
pressure-sensing switch monitors oil injection
function.

Oil Pressure Switch
The oil pressure switch is located in the oil distri-
bution manifold and reacts to changes in oil mani-
fold pressure. The EMM supplies and monitors
electrical current to the switch. The switch opens
or closes based on oil distribution manifold pres-
sures. See NO OIL Warning Test on p. 188.
