Wiring Connections:

• Trolling Motor Wiring: Directly wire the trolling motor to the battery, using appropriate gauge wire (#6 to #10) and a circuit breaker or fuse. Ensure the positive wire from the battery connects to the circuit breaker, and the negative wire goes directly to the negative terminal of the battery.
• Fish Finder Wiring: Use shielded cable (#18 or #12-14 gauge) for the fish finder to minimise interference. Run the cable from the fish finder, under the gunwale, along the floor, and up to the trolling motor. Secure the cable with adhesive mounts or cable clamps every 18"-24". Connect the cable to the output of the integrated transducer inside the mount, using waterproof tape and sealant to prevent water intrusion.
• Networking the Devices: Connect the fish finder to the trolling motor via a wired Ethernet connection (using a Cat5e or Cat6 cable) or a wireless network. For wireless connection, enable Wi-Fi on the fish finder and connect to the trolling motor's wireless access point.

Troubleshooting and Safety:

• Interference Issues: Running the trolling motor and fish finder on the same battery may cause interference on the fish finder display. To minimise this, use separate batteries or shielded cable for the fish finder.
• Voltage Issues: Ensure proper voltage supply to both devices. Check for voltage fluctuations to maintain consistent operation.
• Safety Guidelines: Prioritise physical safety by keeping hair and clothing away from moving parts. Protect against electrical shocks by carefully handling cables and keeping your hands away from the motor when it's running. Choose marine-grade accessories and correctly size the wiring to prevent overheating.

Battery placement

When planning the battery placement for your Jon boat conversion, it is essential to consider weight distribution. Evenly distributing the weight of the battery, fuel tank, and other heavy items can improve the boat's stability and handling. Try to balance the weight between the front and back of the boat as much as possible. Keep in mind that too much weight at the back can make the boat more prone to taking on water, especially when reversing into waves.

Some Jon boat owners choose to place the battery at the front of the boat, especially if they have a trolling motor. This can help counterbalance the weight of the outboard motor and improve weight distribution. It is recommended to use a battery box or cover and a strap to secure the battery in place, protecting it from water and jarring. Additionally, consider using thicker battery cables if the battery is located far from the motor to reduce voltage drop.

On the other hand, some users suggest placing the battery in the rear of the boat, especially if you have a passenger on board. This can help balance the weight distribution and provide more space in the front for other equipment. If you decide to place the battery in the back, ensure that the wires and connections are properly secured and protected from water.

It is also worth noting that the weight of the battery is not the only consideration. The size and power of the motor, as well as the overall weight distribution of the boat, will also impact its performance. Therefore, it is recommended to test the boat with the battery in different positions to determine the optimal placement for your specific setup.

Finally, when it comes to battery placement, it is crucial to use proper wiring and safety measures. Ensure that you use the correct gauge of wire for the length of your battery cables to prevent voltage drop. Additionally, consider using a circuit breaker or fuse to protect the wiring and a main power terminal block for ground connections. Consult a professional or a detailed wiring diagram if you are unsure about the electrical setup.

Battery charging

When it comes to charging the batteries for your Jon boat conversion, there are a few things to keep in mind. Firstly, it's important to choose the right type of battery for your needs. Deep-cycle marine batteries are commonly recommended for Jon boats, as they are designed to provide a steady amount of power over a long period of time. You may also want to consider a gel battery, which is known for its superior performance in long, slower discharges and ability to withstand external heat. Lithium batteries are another option, though they tend to be more expensive.

Once you've selected the appropriate battery type, you'll need to decide on a charging method. One option is to use a battery charger that plugs into a standard home outlet. These chargers are typically used to recharge batteries between outings. When selecting a charger, it's important to choose one that is compatible with your battery type and voltage. For example, if you have a 12V battery, you'll need a 12V charger. You can find battery chargers at marine supply stores or online.

Another option for charging your Jon boat battery is to use a solar panel. This can be especially useful if you plan to be out on the water for extended periods of time or want to minimise the need for shore-based charging. Solar panels can be mounted directly onto the boat and connected to the battery, providing a steady trickle charge that helps to extend the battery's life.

Additionally, it's important to practise proper battery maintenance to ensure optimal performance and longevity. This includes regularly cleaning the battery terminals and checking the battery fluid levels, if applicable. It's also a good idea to store your batteries in a cool, dry place when not in use and to avoid completely discharging them, as this can reduce their lifespan.

Finally, when it comes to battery placement on your Jon boat, consider weight distribution and balance. Placing the battery in the rear of the boat can act as a counterbalance, especially if you have a heavier battery. Just be sure to secure the battery safely and ensure it doesn't shift during use.

Battery sizing

When sizing batteries for a Jon boat conversion, it's important to consider the power requirements of the trolling motor and any additional electronics you plan to install, such as fish finders, livewells, or depth finders. These components can draw a significant amount of power, so it's crucial to ensure your batteries can handle the load.

Deep-cycle marine batteries are typically recommended for Jon boat conversions as they are designed to provide a steady amount of power over an extended period. Unlike starting batteries, which are designed to provide a burst of power to start an engine, deep-cycle batteries are better suited for powering accessories and trolling motors.

The size of the battery you need will depend on the power requirements of your equipment. It's important to calculate the total power draw of all the components you plan to install and select a battery with a capacity that can accommodate this. It's generally recommended to have a battery with a higher capacity than your total power draw to ensure you don't drain the battery too quickly.

Weight is also an important consideration when sizing batteries for a Jon boat conversion. Batteries can be heavy, and the weight can add up quickly, especially if you need multiple batteries. It's important to consider the weight capacity of your boat and ensure that the batteries you choose won't exceed this limit.

Additionally, budget constraints may play a role in your battery sizing decision. Deep-cycle marine batteries can vary in price, and higher-capacity batteries tend to be more expensive. It's important to balance your power needs with your budget to select batteries that fit your requirements without breaking the bank.

Finally, it's worth considering the brand and quality of the batteries you choose. Reputable brands with a track record of performance and reliability are generally recommended for Jon boat conversions.
