Owner's Manual DF60A, DF40A, DF50A Battery Installation

Overpowering your boat can be hazardous. Excessive horsepower will have an adverse effect on hull safety and may cause operating/handling difficulties. The boat may also sustain stress and hull damage.
Never install an outboard motor with horsepower exceeding the manufacturer’s recommended maximum horse power listed on the boat‘s “Certification Plate". Contact your authorized Suzuki marine dealer if you are unable to locate the hull “Certificate Plate”.

It is against federal regulations for any marine dealer to service a motor that exceeds the recommended maximum horsepower for your boat
Suzuki strongly recommends that you have your outboard motor, controls and gauges installed by your authorized Suzuki Marine Dealer. He has the tools, the facilities and the know-how.

Failure to have your outboard motor and associated controls and gauges properly installed can result in personal injury or damage.
Suzuki strongly recommends that you have your outboard motor, controls and gauges installed by your authorized Suzuki marine dealer. He has the tools, the facilities, and the know-how to do the job correctly.

Choose a 12 Volt cranking-type lead acid battery that meets the specifications shown below.

650 Marine Cranking Amps (MCA)IABYC,
or 512 Cold Cranking Amps (CCA)ISAE
or 160 Reserve Capacity (RC) Minutes/SAE

●The specifications listed above are the minimum battery rating requirements for starting the engine.
●Additional electrical loads from the boat will require larger capacity batteries. Consult your Suzuki dealer to determine the proper battery sizing for your boat and engine combination.
●Dual-purpose (Cranking/Deep-cycle) batteries can be used if they meet the minimum specifications listed above (MCA, CCA, or RC).
●Do not use a Deep Cycle battery for the main cranking battery
●The use of Maintenance-Free, sealed, or GelCell 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. Consult your Suzuki dealer for proper battery installation information.

BATTERY INSTALLATION

Secure the battery in a dry area of the boat, away from vibration.

●It is recommended that the battery be installed in an enclosed battery case.
● When connecting batteries, hexagon-nuts must be used to secure battery leads to batteryposts.
To hook up the battery, first connect the red lead from the motor to the positive battery terminal, then connect the black lead to the negative battery terminal.

If you place the battery near the fuel tank, a spark from the battery may ignite the gasoline, causing a fire and/or an explosion.
Do not place the fuel tank in the same compartment/area as the battery.

To remove the battery, first disconnect the black lead from the negative terminal, then disconnect the red lead from the positive terminal.

Connecting and disconnecting the battery as described above will help minimize the chance of creating an accidental short circuit and sparks.

Suzuki recommends that you install the terminal cap on the positive battery terminal to prevent an accidental short circuit of battery terminals.

If a terminal cap is required, contact your authorized Suzuki marine dealer.

Batteries produce flammable hydrogen gas and may explode if they are near flames or sparks.
Never smoke or cause sparks when working near the battery. Keep the battery away from open flames. To avoid creating a spark when charging the battery, connect the battery charger cables to the proper terminals before turning the charger on.

Battery acid is poisonous and corrosive.
It can cause severe injury and can damage painted surfaces.
Avoid contact with eyes, skin, clothing, and painted surfaces. It battery acid comes in contact with any of these, flush immediately with large amounts of water.
If acid contacts the eyes or skin, get immediate medical attention.

The electrical system or its components may be damaged if proper battery pre- cautions are not followed.

●Be sure to attach battery leads correctly.
●Do not disconnect battery leads from the battery while the engine is running.

USE OF ELECTRICAL ACCESSORIES

The amount of power (12V DC) available for accessories depends on the operating condition of the motor. For getting a detailed information, please inquire of your authorized Suzuki Marine Dealer.

Use of too much power for electrical accessories under certain operating conditions can cause the battery to discharge.

PROPELLER SELECTION

it is essential to use a propeller on your out- board motor that is properly matched to your boat’s operating characteristics The speed of the engine when you operate your boat at full throttle depends on the propeller you use.
Excessive engine speed can seriously damage the motor. while low engine speed at full throttle will adversely affect the performance. Your operating load will also affect propeller selection. Smaller loads generally require larger-pitch propellers; larger loads generally require smaller-pitch propellers. Your authorized Suzuki Marine Dealer will assist you in selecting a suitable propeller for your boat.

Installing a propeller with either too much or too little pitch will cause incorrect maximum engine speed, which may result in severe damage to the motor.

Ask your authorized Suzuki marine dealer to assist you in selecting a suitable propeller for your boat.

You can determine if your propeller is appropriate for use with your boat by using a tachometer to measure engine speed when operating your boat at full throttle. under minimum load conditions. If you are using an appropriate propeller. the engine speed will be within the following range:

If the engine speed is not within this range, consult your authorized Suzuki Marine Dealer to determine which propeller size is best for you.

If you change propellers, be sure to perform the above check again, to confirm that the engine speed under full throttle is within the specified range.
