ADJUSTMENTS
LUBRICATION
Throttle Friction
Gearcase
Adjust until a slight drag is felt when accelerating or
decelerating only. DO NOT overtighten. If adjust-
ment is necessary, turn the adjustment screw:
Replace gearcase lubricant after first 10 hours of
operation. Check level and condition of lubricant af-
ter next 50 hours of operation. Add lubricant if nec-
essary.

Clockwise to increase friction
Counterclockwise to decrease friction
Thereafter, check level and condition of lubricant
every 50 hours. Replace lubricant every 100 hours
of operation or once each season, whichever oc-
curs first. Refill with Ultra-HPF gearcase lubricant.
If not available, Hi-Vis™ or other marine gearcase
lube can be used, however, long term durability
may be affected with continued use. See your Deal-
er.

IMPORTANT: The recommended gear lubricants
include special additives for marine applications.
Do not use automotive gear lubricants, 2-stroke or
4-stroke
engine oil, or any other oil or grease for
gearcase applications.

With motor in normal operating position:
1)
Remove drain/fill plug and lubricant level plug
from side of gearcase and completely drain
gearcase of old lubricant.
Steering Friction
The steering friction was set on your new motor be-
fore it left the factory. After the first 10 hours of ser-
vice, check to see that it is still correct; a slight drag
should be felt when turning the motor. If adjustment
is necessary, turn the adjustment screw:
2)
Examine drained lubricant for metal filings,
milky appearance, or black color with burnt
odor. If old lubricant has any of those charac-
teristics, see your Dealer. If drained lubricant
is in good condition, continue.

3)
Place tube of lubricant in drain/fill hole and fill
slowly until lubricant appears at lubricant lev-
el hole. See Engine Specifications for gear-
case capacity.
4)
5)
Install lubricant level plug before removing
tube from drain/fill hole. Drain/fill plug can
then be installed without loss of lubricant.
Securely tighten both plugs.

IMPORTANT: To avoid insufficient injection of lu-
bricant, check the gear oil level 10 minutes after fill-
ing. If the oil level is low, slowly inject the lubricant
up to the correct level.
