OILING SYSTEM
OIL CONTROL SETTINGS
Check valves pre ssed into the cra nkcase b elow
#4 and #6 ree d valve assemblies connect to
hoses which route to a fitting at the top of the
block, above #2 cylinder.
Crankcase / Main Bearing Recirculation
The movement of oil through the main bearings is
controlled b y in ternal p assages, exter nal fitting s
and hoses, and an in-line check valve.
Both cent er ma in be arings receive oil throu gh
grooved passages in th e crankcase. Oil migrate s
to the bearings from th e crankcase a reas of the
higher cylinders.
The lower main bearin g receives oil thro ugh a
grooved passage in the crankcase.
Lower to upper main bearing oil flow
Oil moves from the lower main b earing cavi ty
through an internal cran kcase p assage to an
external fitting. Ext ernal hoses with an in-line
check valve connect to a f itting at the upper main
bearing, which leads to t he up per main bearing
through an internal crankcase passage.
OIL CONTROL SETTINGS
Oil Injection Rate
The Engine Management Module (EMM) controls
the oil injection rate based on engine RPM. This
rate can be adjusted for the type of oil being used,
and also for powerhea d break-in. Use Evinrude
Diagnostics software to access these features.
The Set Oil Type option controls the injection rate
for the oil being used and typical operating condi-
tions.
The TC-W3 oil type setting is the standard setting
for all outboards. Set TC-W3 for:
• Operation with a ll TC-W3 outboard o ils in clud-
ing XD30, XD50, or XD100.
• Applications requiring maximum lubrication.
• Extreme applications (commercial or harsh con-
ditions, racing or other high performance opera-
tion).
• Use this set ting with XD100 outb oard oil in
extreme applications
The XD100 setting provides an option to run the
outboard at a reduced oil injection rate. This set-
ting REQUIRES the use of Evinrude XD100 ou t-
board lubrican t and is not recommend ed for all
applications.
IMPORTANT: The XD100 setting is not avail-
able on all models.
Use the XD100 setting for:
• Conventional use (runabouts, cruisers)
• Moderate applications
1. Lower to upper main bearing oiling circuit
2. Idle oil circuit
3. Tee fitting
4. Cylinder recirculation circuit
