MOTOR
Recheck the measurements, and verify the
boat transom vertical centerline is straight.
Measurements (a) and (b) should be the
same, and measurement (c) and (d) should be
the same.
If mounting twin motors, set the motors so
that the distance between the boat transom
center line and the motor center line should be
equal for the both motors.
(e)
Measurements (e) and (f) should be the same.
Maintain a minimum distance (T1) that is the
measurement between both vertical center-

Minimum distance (T1) is recommended on
each model, and its data is put on the dimen-
sion item.
