LUBRICANT
Draining
Remove the lubricant level plug, then the lubricant
drain/fill plug, and drain the lube from the gear-
case into a container. Inspect the lubricant for
metal chips.
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.
WARNING
When servicing the propeller, always shift
the outboard to NEUTRAL, turn the key
switch OFF, and disconnect the battery
positive (+) cable so the outboard cannot
be started accidentally.
WARNING
Gearcase lubricant may be under pressure
and/or hot. If plug is removed from a
recently operated outboard, take precau-
tions to avoid injury.
TYPICAL
1. Lubricant level plug
2. Lubricant drain/fill plug
