Apply Permatex No. 2 to both sides of a new base
gasket around the exhaust port only. Install gasket
on exhaust housing. To ensure proper sealing,
mating surfaces must be clean and dry.
Coat the driveshaft splines with Moly Lube. Do not
apply lubricant to end of driveshaft.
Use Lifting Fixture, P/N 396748, and hoist to
slowly lower powerhead onto exhaust housing. If
necessary, rotate flywheel in a clockwise direction
to align crankshaft and driveshaft splines.
Apply Triple-Guard grease to the threads, and
Gasket Sealing Compound to the shank of the
powerhead screws.
Loosely install all powerhead screws before tight-
ening:
Tighten the eight powerhead screws to a torque of
18 to 20 ft. lbs. (24 to 27 N·m) in the sequence
shown.
IMPORTANT: Retighten powerhead mounting
screws after outboard has been run at full operat-
ing temperature and allowed to cool.
