IMPORTANT: If outboard is installed higher than
normal (anti ventilation plate out of the water), re-
move auxiliary water inlet screen (in front of the trim
tab). Install plate, P/N 5031618, with screws saved,
to prevent overheating and engine damage.
LUBRICATION
Gearcase
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.
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
DEALER.

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

Throttle Friction
1)
Remove drain/fill plug and lubricant level plug
from side of gearcase and completely drain
gearcase of old lubricant.
Adjust throttle friction on your remote control to
maintain its position and prevent unwanted throttle
“creep” under normal operating conditions.
To adjust, start engine and move control handle
into FORWARD throttle range. While underway,
turn adjustment knob clockwise to increase friction.
The friction adjustment is effective only in the
FORWARD throttle range.
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 lubri-
cant 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.
