exhaust
outlet, andis forced through
the coolingsys-
tem, later to be discharged at the outlet in the ex-
haust tube provided for this purpose. Water enters
the cooling system through the holes in the watgr
by-pass cover above the anti-cavitation plate when
operating in REVERSE. (See
Figure 1 for locations
of cooling system parts.)
NOTE
I1, while operating motor at full speed, it
should show signs of slowingdown, immedi-
ately check water drscharge at water outlet
(Figure B) located at rear of the motor di-
rectly below cylinder. In case no watei is
being discharged, immediately shut off the
motor and check water inlet (Figure 8) for
obstruction. If no obstruction is found, it
may indicate worn pump parts.
REMOVING
MOTOR
FROMBOAT
At end of run, with motor running in NEUTRAL,
plose fuel shut-off valve and permit motor torununtil
it stops, draining carburetor. Close air vent screw
in filler cap. The motor can then be carried with-
out fuel leakage. For safety, always drain fuel
tank before transporting motor. Also drain water
thoroughly as in "Care of Motor in CoId Weather. "
When removing motor from boat, Iift motor in a
straight upward position and hold this position for
a brlef period until aII water is drained from the
underwater exhaust tube and water cooling system.
Do not stand motor on top or carry with the top down
before draining water, as this may allow water to
enter the power head from underwater exhaust tube.
CARE
OFMOTOR
INCOLD
WEATHER
The motor will not freeze while in use, but when it
is idle, water in the cylinders or pump might lreeze
and damage the motor. Drain by setting the motor in
an upright position and pulling starter cord several
times with speed control grip in STOP position. If
the motor is to be stored during cold weather, be
sure that no water is left in the motor or it mav
freeze. (See "Preparation for Storage. ")
SALT
WATER
INSTRUCTIONS
A little time spent in caring for your motor whenused
in salt water will aid in not only keeping it in good
running order but help in retaining its finish and ap-
pearance. Tilt the motor out of the water when it is
not in use. At the end of the day or when not using
the motor for a period of time it is advisable to re-
move it from the boat and to flush it by running it in
a tank of fresh water. Wipe the motor dry and go
over all parts with an oily cloth. This should be
done as soon as possible after removing the motor
from the boat.
PREPARATION
FOR
STORAGE
No outboard motor should
be placed
in storage
with-
out considering
the necessaryprecautions. U motor
Coreol
yourlulolor
is operated in salt watet, flush by running in a tank
of fresh water. Drain and refill gear case with the
proper lubricant. See page 5.
Prior to storing the motor, run it for about one-half
(172) minute in choke position. Shut off motor with-
out pushing choke back to normal position. Purpose
of this operation is to flood the inner parts of tlie
powerhead with oil (oil in fuel mixture) while in
storage.
Drain all water from the cooling system. See "Care
of Motor in CoId Weather. "
Drain all fuel from fuel tank, gas.line and carbure-
tor.
Under no circumstances should the motor be stored
in an inverted position. It should be hung on a rack
similar to the manner in which it is mounted on the
boat. Store in a dry place. Wrap the motor in a
piece of canvas, old blanket. or heavy paper.
PUTTINGMOTOR
INUSEAFTERSTORAGI
Pull off spark plug Ieads and remove spark plugs.
If rubber spark plug hoods have been removed from
ignition leads, be sure to ground Ieads to some part
of motor to prevent possibility of spark. (THIS IS
IMPORTANT. ) Spin motor by pulling on starter cord
to remove excess oil from cylinders. Clean spark
plugs, check gap and replace. InstaII new plugs if
they are cracked, broken, or badly burned. Tighten
a-llscrews and nuts. Check adjustments such as tilt-
ing friction, co-pilot, and carburetor knob.
RUNNING
MOTOR
IN
TESTTANK
1. Do not run motor out of water.
2. Do not "break-in" motor in tank.
3. Remove water by-pass cover (small metal strip
on lower port side of upper pump housing, Figure B).
4. When running in tank be sure gear housing and
propeller are submerged.
5. Do not race motor in tank.
6. Use test propeller when testing motor in tank.
7. Cavitation (air pocket around propeller) may occur
when operating motor in tank with regular propeller.
Motor will then not perform properly or it may race
and be damaged as a result.

SUBMERGED
Precaution should be taken to prevent a motor going
overboard (see page 1). However, if a motor has
been submerged, it should be recovered as quickly
as possible.
Since the motor is temporarily out of working order,
do not attempt to operate it untii the following pro-
cedure has been used to restore it to service.
