Align the end cap notch or mark with the
mark on the frame and the upper cap mark
with its mark.
Slide the rubber spacer or collar into the
starter bracket, if used. Now, install the
starter bracket over the starter motor. In-
stall the thru-bolts through the end cap, the
frame, and thread them into the starter
bracket. Tighten the thru-bolts securely.
To test the assembled starter motor, see
the next section.
To install the starter motor, proceed
directly to Section 6-17.
6-16 STARTER MOTOR TESTING
Clamp the starter motor in a vise equip-
ped with soft jaws, as shown, and test its
operation.
CAUTION: The armature will turn rap-
idly during this test. Therefore, the starter
motor MUST be well SECURED before mak-
ing the test to prevent personal INJURY or
damage to the starter motor.
Firmly connect one end of a heavy-duty
jumper wire to the POSITIVE terminal of a
battery. Firmly connect the other end of the
jumper lead to the starter motor terminal.
Connect a second heavy-duty jumper
wire to the negative terminal of the bat-
tery. Now, MOMENTARILY make contact

motor. NEVER make the momemtary con-
tact with the positive lead to the terminal,
because any arcing at the terminal may
damage the terminal threads and the nut
may not take to the damaged threads. The
motor should turn rapidly. If the starter
motor fails to rotate, the starter motor
must be disassembled again and the service
work carefully checked. Sorry about that,
but some phase of the rebuild task was not
performed properly.
6-17 STARTER MOTOR INSTALLATION
Mount the starter motor and bracket
onto the engine. Align the top bolt above
the carburetor, and then thread it into the
block about half-way. Align the other three
bolts on the starboard side or start the nuts
onto the studs, depending the model engine
being serviced. Tighten the three on the
side evenly and alternately until they are
secure.
Connect the positive red lead to the
starter motor. Connect the electrical lead
to the battery. Test the completed work by
cranking the engine with the starter motor.
DO NOT, under any circumstances, start
the engine unless it is mounted in a test
tank or body of water.
CAUTION: Water must circulate through
the lower unit to the engine any time the en-
gine is
run
to prevent damage to the water
pump in the lower unit, Just five seconds
without water will damage the water pump.
