WARNING
Gearcase lubricant may be under pressure
and/or hot if plug is removed from recently
operated outboard. Take precaution to
avoid injury.
Remove the lubricant level plug, then the lubricant
drain/fill plug, and drain the lube from the gear-
case into a container. Inspect the lube and the
plugs for metal chips.
1. Lubricant level plug
2. Lubricant drain/fill plug
The presence of metal fuzz can indicate normal
wear of the gears, bearings, or shafts within the
gearcase. Metal chips can indicate extensive
internal damage.
Inspection
Inspect the lubricant for water contamination.
Water can make the lubricant milky in appear-
ance. However, normal aeration can also cause
the same appearance.
To check for water contamination, drain lubricant
into a suitable glass container. Allow the drained
oil to settle for a minimum of one hour to deter-
mine if there is an abnormal amount of water in
the oil. Some gearcase lubricants are designed to
mix with a small amount of water from normal
water vapor condensation within the gearcase.
Overheated lubricant will have a black color and
burned odor.

Internal gearcase inspection is recommended
when lubricant is contaminated or shows signs of
failure.
Filling
Secure the gearcase in a vertical position.
Remove the lubricant level plug and the lubricant
drain/fill plug.
Slowly fill the gearcase with HPF XR gearcase
lube through the drain/fill hole until it appears at
the oil level hole. Filling the gearcase too quickly
can cause air pockets and the gearcase may not
fill completely.
If using pressurized lubricant tank, use fitting
adapter, P/N 772269.
