Cleaning and Inspection
•
Clean all parts with cleaning solvent and dry
with compressed air.
•
All nut and screw threads that are coated with
Nut Lock
or
Screw Lock
must be thoroughly
cleaned before assembly. When using a thread
locking product, prime the threads with Locquic
Primer.
•
Discard all oil seals, O-rings, and gaskets. Use
new components during assembly.
•
Check all bushings for wear and proper fit.
Replace if necessary.
•
Inspect the rubber motor mounts. Replace if
deteriorated or damaged.
•
Inspect the water tube for obstructions or kinks
which may restrict water flow. Replace the
grommet if worn or damaged.
•
Inspect the stern brackets, swivel bracket, and
steering arm for cracks and other damage.
•
Inspect the shift components for wear. Replace
if deteriorated or damaged.
Before checking the driveshaft or oil pan housings
for distortion, thoroughly clean the top and bottom
mating surfaces and remove all sealer and corro-
sion.
Check the driveshaft and oil pan housings for dis-
tortion. Place the housing on a surface plate. Use
a dial indicator to check the flatness by measuring
the run-out on the top edge of the housing. The
maximum allowable run-out is 0.009 in. (0.228
mm).
If you do not have access to a dial indicator and a
surface plate, seek the services of a machine
shop. DO NOT attempt to straighten a distorted
housing. Replace it.
IMPORTANT:
A bent driveshaft or oil pan hous-
ing will cause the upper driveshaft splines to wear
excessively and will also damage the crankshaft
splines. Additionally, a distorted upper oil pan
housing can result in loss of oil or allow water to
enter the oil.
