Suzuki DF4A Owner's Manual page 16

Center the motor on the transom and secure it
by alternately tightening the clamp bracket
screws by hand. Make sure you accurately cen-
ter the motor, or the boat will pull to one side
during operation.
Install 8 mm bolts, washers, lock washers and
nuts, as illustrated and tighten the bolts sequen-
tially. Be sure to seal the holes with sealant to
prevent water leakage.
NOTICE
Over tightening the transom bolts can
damage the clamp bracket.
• Do not over tighten the transom bolts.
• Do not use an impact tool to tighten or
loosen the transom nuts.

After installing the motor, check to make sure
that steering and tilt movement are not
obstructed by any part of the boat. Also make
sure that the battery cable (if provided) doesn't
interfere with movement of the motor.
 WARNING
If the motor is not properly secured to the
transom, it can come off.
Be sure to bolt the motor to the transom.
The motor may come off if it is held only
by the clamp screws. Occasionally check
the clamp screws for tightness.
NOTICE
If you attempt to mount the outboard to
the transom without having mechanical
experience or without being certain
where to drill holes, you can seriously
damage the boat.
If you do not have mechanical experience
or are not sure of where to drill holes in
the boat's transom, you should have your
motor mounted by your authorized
Suzuki marine dealer.
