SERIAL NUMBER

The outboard motor’s serial number is

stamped on a label which is attached to the

port clamp bracket.

NOTE:

As an antitheft measure, a special label on

which the outboard motor’s serial number

is stamped is bonded to the port clamp

bracket. The label is specially treated so

that peeling it off causes cracks across the

serial number.
