Powerhead Reassembly and
Installation
General Information
Before proceeding with powerhead reassembly, be
sure that all parts to be reused have been carefully
cleaned and thoroughly inspected, as outlined in
“Cleaning and Inspection”. Parts, which have not
been properly cleaned (or which are questionable),
can severely damage an otherwise perfectly good
powerhead within a few minutes of operation. All new
powerhead gaskets must be installed during
assembly.
During reassembly, lubricate parts with Quicksilver
2-Cycle Outboard Oil whenever 2-cycle oil is speci-
fied and Quicksilver 2-4-C w/Teflon whenever grease
is specified.
A torque wrench is essential for correct reassembly
of powerhead. Do not attempt to reassemble power-
head without using a torque wrench.
EXAMPLE: If Exhaust Cover bolts require a torque of
220 lb. in. (24.9 Nm), a) tighten all bolts to 73 lb. in.
(8.2 Nm), following specified torque sequence, b)
tighten all bolts to 146 lb. in. (16.5 Nm), following
torque sequence, then finally, c) tighten all bolts to
220 lb. in. (24.9 Nm), following torque sequence.
