CLEANING AND
INSPECTION

General

WARNING
To avoid personal injury, wear eye protec-
tion and set compressed air pressure to
less than 25 psi (172 kPa).
•
Clean all parts with cleaning solvent and dry
with compressed air.
•
All nut and screw threads that are coated with
Screw Lock or Nut 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 tilt assist cylinder (or PTT unit) for
cracks and other damage. If replacement is
necessary, replace
assembly.
•
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.

Clamp Screw

Inspect the clamp screw assembly(s). Replace the
swivel plate and retainer if they are bent or loose.
To install a new swivel plate, remove the screw
and old plate. Apply Locquic Primer to the threads
of the screw and allow it to dry for four to five min-
utes. Then apply Ultra Lock to the threads. Install
a new swivel plate and tighten the screw securely.

Exhaust Housing

Before checking the exhaust housing for distor-
tion, thoroughly clean the top and bottom mating
surfaces and remove all sealer and corrosion.
Check the exhaust housing for distortion. Place
the housing on a surface plate. Use a dial indica-
tor 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 exhaust housing will
cause the upper driveshaft splines to wear exces-
sively and will also damage the crankshaft
splines.
