Whenever components are removed for service,
they should be retained in order. At the time of instal-
lation, they should be installed in the same locations
and with the same mating surfaces as when re-
moved.
Before raising or removing and outboard engine from
a boat, the following precautions should be adhered
to:
1. Check that flywheel is secured to end of crank-
shaft with a locknut and lifting eye is threaded into
flywheel a minimum of 5 turns.
2. Connect a hoist of suitable strength to the lifting
eye.
In addition, personnel should not work on or under an
outboard which is suspended. Outboards should be
attached to work stands, or lowered to ground as
soon as possible.
We reserve the right to make changes to this manual
without prior notification.
Refer to dealer service bulletins for other pertinent in-
formation concerning the products described in this
