Pre-Disassembly Inspection
IMPORTANT:
Clean and inspect all parts during
disassembly. Replace any damaged parts, seals,
O-rings, and gaskets.
Remove the propeller and mounting hardware.
Drain and inspect oil as described in
Remove gearcase. Refer to
Remove water pump. Refer to
Before disassembling the gearcase, examine the
following:
•
Gearcase Housing —
Check for visible dam-
age to skeg, strut, anti-ventilation plate, bullet,
and mating surface. Check seal areas for visible
signs of lubricant leakage.
•
Propeller Shaft —
Check for bent or damaged
shaft. Check for twisted splines and damaged
threads.
•
Shift Rod —
Check for misadjusted, bent, or
binding rod. A misadjusted shift rod height can
cause shift difficulty, loss of boat and outboard
control, and gearcase damage.
•
Hydrostatic Seal Grooves —
Must be in good
condition to help prevent propeller ventilation.
•
Gearcase Anodes —
If anodes have eroded to
two-thirds their original size, they must be
replaced.
•
Drive Shaft —
Check splines for visible dam-
age, twisting and wear. Severe spline wear indi-
cates the exhaust housing or gearcase has
been distorted, possibly by impact damage.
•
Water Intake Screens —
Check for damage
and blockage. If screens cannot be cleaned,
they must be replaced. Different screens are
available and should not be mixed. Refer to cor-
rect model parts manual for listing and descrip-
tion.
