MAINTENANCE
LUBRICATION
Gearcase Lubricant
IMPORTANT:
Always check the fill level of the
gearcase lubricant prior to removing drain/fill plug.
A tie strap can be used to check lubricant level.
Examine drained lubricant for excessive metal
fragments and for any indication of water in oil
(cloudy or milky appearance). Lubricant that is
black in color with a burnt odor indicates worn,
overheated oil. Pressure and vacuum check gear-
cases with apparent leaks. Repair all leaks.
Refer to INSPECTION AND MAINTENANCE
SCHEDULE on p. 50 for service frequency and
recommended lubricants.
Refer to LUBRICANT on p. 165 for complete
gearcase lubricant filling procedures.
REFILL the gearcase with HPF XR Gearcase
Lubricant.
If HPF XR Gearcase Lubricant is not available, Hi-
Vis gearcase lubricant can be used as an alterna-
tive; however, long term durability may be affected
with continued use.
IMPORTANT:
The recommended gear lubri-
cants include special additives for marine applica-
tions. Do not use any automotive gear lubricants,
2-stroke or 4-stroke engine oil, or any other oil or
grease for gearcase applications.
Propeller Shaft
Debris from the water can become lodged around
propeller shaft. Frequent inspection can minimize
potential gearcase damage.
Remove propeller. Refer to Propeller Hardware
Installation on p. 47.
Inspect bushing and blade surfaces. Replace
damaged or worn propellers.
Clean propeller shaft. Inspect propeller shaft
seals. Replace damaged or worn seals.
Apply Triple-Guard grease to entire length of pro-
peller shaft prior to installing propeller.
Reinstall propeller hardware and propeller.
