lake. The outboard is carried only as a last
resort -- in case the wind fails completely,
or in an emergency situation.
As a result, the outboard is stowed be-
low, usually in a very poorly ventilated area,
and subjected to moisture, stale air --in
short, an excellent enviroment for "sweat-
ing" and corrosion.
If the dyed-in-the-wool "rag bagger"
could just take the time about once every
month or two, to pull out his outboard, clean
it up, and give it a short run, not only would
he have "peace of mind" knowing it WILL
start in an emergency, but also his mainten-
ance cost will be drastically reduced.
Chapter Coverage
The material presented in this chapter is
divided into five general areas.
1- General information every boat own-
er should know.
2- Maintenance tasks that should be per-
formed periodically to keep the boat operat-
ing at minimum cost.
3- Care necessary to maintain the ap-
pearance of the boat and to give the owner
that "Pride of Ownership" look.
4- Winter storage practices to minimize
damage during the off-season when the boat
is not in use.
5- Preseason preparation work that
should be performed to ensure satisfactory
performance the first time it is put in
service.
In nautical terms, the front of the boat
is the bow and the direction is forward; the
rear is the stern and the direction is aft;

the right side, when facing forward, is the
starboard side; and the left side is the port
side. All directional references in this man-
ual use this terminology. Therefore, the
direction from which an item is viewed is of
no consequence, because starboard and port
NEVER change no matter where the individ-
ual is located or in which direction he may
be looking.
10-2 ENGINE SERIAL NUMBERS
The engine serial numbers are the manu-
facturer's key to engine changes. These
numbers identify the year of manufacture,
the qualified horsepower rating, and the
parts book identification. If any correspon-
dence or parts are required, the engine
model number MUST be used or proper iden-
tification is not possible. The accompanying
illustrations will be very helpful in locating
the engine identification tag for the various
models.
ONE MORE WORD
The model number establishes the year
in which the engine was produced and not
neccessarily the year of first installation.
On some model engines, the serial numb-
er and model number were stamped on a
plate mounted between the two swivel brac-
kets underneath the hood.
On other model engines, the plate is
mounted on the port side of the engine on
the front or side of the swivel bracket. The
hp and rpm range will also be found on the
plate.
