Powerhead Reassembly
General
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,”
preceding. Parts, which have not been properly cleaned (or which are questionable), can
severely damage an otherwise perfectly good powerhead within the first few minutes of
operation.
New gaskets MUST BE installed during reassembly.
During reassembly, lubricate parts with Quicksilver 4-Cycle Outboard Oil whenever “light
oil” is specified. Quicksilver part numbers of lubricants, sealers and locking compounds are
listed under “Quicksilver Lubricants and Service Aids,” preceding.
A torque wrench is required for correct reassembly of powerhead. DO NOT attempt to reas-
semble powerhead without using a torque wrench. Attaching bolts for covers and housings
MUST BE torqued by tightening bolts in 3 progressive steps (following specified torque se-
quence) until specified torque is reached. Powerhead torques are listed under “Torque
Specifications,” preceding.
