0A-5 General Information:
Battery Requirement
Suzuki recommends a 12 volt cranking type lead acid
battery for the DF70A / 80A / 90A.
Minimum battery requirement for starting the engine is
provided below.
The battery must satisfy one of the specifications
described below.
NOTE
• The specifications listed below are the
minimum battery rating requirements for
starting the engine.
• Additional electrical loads from the boat
will require larger capacity batteries.
• Dual-purpose (Cranking / Deep Cycle)
batteries can be used if they meet the
minimum specifications listed below
(MCA, CCA, or RC).
• Do not use a Deep Cycle battery for the
main cranking battery.
• The use of Maintenance-Free, sealed, or
Gel-Cell batteries is not recommended
because they may not be compatible with
Suzuki's charging system.
• When connecting batteries in parallel, they
must be of the same type, capacity,
manufacturer, and of similar age. When
replacement is necessary, they should be
replaced as a set.
• It is recommended that the battery be
installed in an enclosed case.
• When connecting batteries, hexagon nuts
must be used to secure battery leads to
battery terminals.

Powerhead Direction of Rotation Description
Z9J0110101018
This outboard motor is designed with a L.H. (left hand)
rotation powerhead utilizing an offset crankshaft. This
design has the advantage of reducing the size of the
motor and keeping the overall motor's weight closer to
the boat transom and therefore closer to the boat C/G
(Center of Gravity).
Rotation of the driveshaft is accomplished through a
crankshaft drive gear and a driveshaft driven gear.
These gears are located beneath the powerhead in the
same oil bath location as the camshaft chain.
As the rotational direction of the driven gear will be
opposite of the drive gear, a left hand rotation
powerhead design was adopted to retain a conventional,
standard rotation (right hand) propeller shaft output.
