GEARCASE LEAK TEST
Drain lubricant before testing.
Use Gearcase Pressure Tester, P/N 507977.
Install lubricant drain/fill plug and seal, thread
pressure test gauge fitting and seal in lubricant
level hole.
Pressurize 3 to 6 psi (21 to 42 kPa).
If pressure gauge indicates leakage, submerge
the gearcase in water to determine source of leak.
If the gauge does not indicate leakage, increase
pressure to 16 to 18 psi (110 to 124 kPa). Check
for leaks.
Make necessary repairs and repeat test.
Install Gearcase Vacuum Tester, P/N 507982.
Apply 3 to 5 in. of vacuum (76 to 127 mm) Hg.
with pump.
If vacuum gauge indicates leakage, apply oil
around suspected seal. If leak stops or oil is
drawn in, seal is defective.
Repeat test, gearcase must hold minimum of 15
in. vacuum (381 mm) Hg.
TRIM TAB SERVICE

Note where the index mark on the gearcase aligns
with the index mark of the adjustable trim tab so
the trim tab can be installed in the same position.
Remove the trim tab retaining screw and trim tab
from the gearcase.
Installation
Apply Gasket Sealing Compound to threads of the
trim tab screw. Install and align the trim tab with
the index marks noted prior to disassembly.
Tighten the trim tab screw to a torque of 60 to 84
ft. lbs. (7 to 9.5 N·m). For adjustment, refer to
