Choosing the Right Trolling Motor for Your Jon Boat
Before you even think about drilling holes, selecting the correct trolling motor is paramount. Several factors will influence your choice, impacting performance and ease of installation.
Thrust and Boat Size
Thrust, measured in pounds (lbs), determines how much pushing power your motor has. A good rule of thumb is to have at least 2 lbs of thrust for every 100 lbs of fully loaded boat weight (including passengers and gear).
For most jon boats, which are typically lighter, a motor in the 30-55 lb thrust range is common. Longer or wider jon boats, or those frequently used in windy conditions, might benefit from higher thrust.
Shaft Length Considerations
The shaft length is critical for optimal propeller depth. If it’s too short, the prop will come out of the water in choppy conditions. Too long, and it can drag or hit obstacles.
Measure the distance from where the motor will mount to the waterline. Add 20 inches to this measurement for bow-mount motors. For transom-mounts, ensure the propeller sits at least 12 inches below the water’s surface when deployed.
Bow Mount vs. Transom Mount
Bow mount motors offer superior control and maneuverability, especially for fishing. They pull the boat rather than push it, making steering more intuitive. These typically use foot pedals or remote controls.
Transom mount motors are simpler to install and often more affordable. They attach to the stern of the boat and are usually hand-controlled. They are great for smaller jon boats or as a secondary motor.
Power System (12V, 24V, 36V)
The motor’s thrust rating usually dictates its voltage requirement. Lower thrust motors (30-55 lbs) often run on a single 12V marine deep-cycle battery. Higher thrust models (55-80 lbs) usually require a 24V system (two 12V batteries in series), and very powerful motors (80+ lbs) need a 36V system (three 12V batteries).
Always match your motor’s voltage requirements to your battery setup. This is crucial for proper operation and battery longevity.

Pre-Installation Checklist: Planning for Success
A little planning goes a long way. Before you pick up any tools, run through this checklist.
Read Your Motor’s Manual
Every trolling motor is slightly different. The manufacturer’s instructions will have specific recommendations for mounting, wiring, and maintenance. Do not skip this step!
Choose Your Mounting Location
For a bow mount, ensure there’s enough clear deck space. Consider the motor’s stowed position – will it interfere with fishing, anchor lines, or walking space? For a transom mount, check for obstructions like fuel lines or other accessories.
Ensure the mounting surface is strong and flat enough to support the motor’s weight and torque. Jon boats sometimes have ribbed or uneven decks that may require a mounting plate or shims.
Battery Placement
Decide where your battery box will go. It should be in a dry, secure location, preferably as close to the motor as possible to minimize cable length. Common spots include under a bench seat or in a dedicated battery compartment.
Ensure the battery is easily accessible for charging and maintenance, but also out of the way to prevent accidental damage or tripping hazards.
Gather Your Safety Gear
Working with power tools and electricity requires caution. Wear safety glasses, gloves, and ensure a stable working environment. Always disconnect the battery before making any electrical connections.
Step-by-Step: How to Mount Trolling Motor on Jon Boat (Bow Mount)
This is where the rubber meets the road. Follow these steps carefully to ensure a secure and functional installation.
1. Position the Mounting Bracket
Place the trolling motor’s mounting bracket on the bow of your jon boat. Ensure the motor, when stowed, doesn’t obstruct your view or path. When deployed, the shaft should clear the bow and the propeller should be deep enough.
Rotate the bracket to ensure the motor has a full range of motion without hitting the boat’s gunwales or other equipment. Use your measuring tape to center the bracket if desired.
2. Mark and Drill Holes
Once you’re happy with the placement, use a marker to trace the bolt holes through the bracket onto the boat’s deck. Double-check your marks before drilling.
Using a drill bit slightly larger than your chosen bolts, carefully drill through the marked spots. Start with a smaller pilot hole if you’re unsure. Be mindful of anything beneath the deck that could be damaged.
3. Apply Marine Sealant
This is a critical step for preventing water intrusion. Apply a generous bead of marine-grade silicone sealant around each drilled hole, both on top of the deck and underneath if accessible.
This creates a watertight seal, protecting your boat”s hull from rot and preventing leaks.
4. Secure the Bracket
Align the bracket with the drilled holes. Insert the stainless steel bolts from the top down, through the bracket and the boat’s deck.
From underneath, place a washer and then a nut on each bolt. Hand-tighten all nuts first, then use your wrench or socket to snug them down. Do not overtighten, as this can damage the fiberglass or aluminum, but ensure they are very secure. The sealant will squish out – wipe away any excess for a clean finish.
5. Attach the Trolling Motor to the Bracket
Most bow-mount trolling motors simply slide onto or bolt into their quick-release or fixed mounting bracket. Follow your motor’s specific instructions for this attachment.
Ensure all locking pins or bolts are fully engaged to prevent the motor from coming loose during operation or transport. This completes the physical part of how to mount trolling motor on jon boat.
Transom Mount Trolling Motor Installation
Installing a transom mount motor is generally simpler, as it often involves clamping directly to the transom. However, proper placement and security are still key.
1. Choose the Right Side
Decide whether you want the motor on the port (left) or starboard (right) side of the transom. Consider your primary hand for steering and any other equipment (like an outboard motor) that might interfere.
2. Clamp On Securely
Most transom-mount motors have adjustable clamps. Place the motor onto the transom, ensuring the clamps are fully engaged. Tighten the clamp screws firmly by hand, then give them an extra quarter turn with a wrench if possible.
Make sure the motor is centered vertically to allow the propeller to be at the correct depth when deployed. The motor should be secure enough that it won’t vibrate loose from engine use or boat movement.
3. Consider a Mounting Plate (Optional)
If your transom is thin or you want extra protection, consider adding a transom saver plate. This distributes the clamping pressure, reducing potential damage to your boat’s transom over time.
Wiring Your Trolling Motor: Powering Up Safely
Electrical wiring requires careful attention to detail. Incorrect wiring can lead to poor performance, battery damage, or even fire hazards. Safety first!
1. Install the Battery Box and Battery(ies)
Place your marine deep-cycle battery (or batteries) in their designated battery box. Secure the battery box to the boat to prevent it from sliding around, especially in rough water.
Ensure the battery terminals are clean and free of corrosion. Use dielectric grease for added protection.
2. Connect the Circuit Breaker/Fuse
An inline circuit breaker or fuse is non-negotiable for safety. Install it on the positive (+) lead, as close to the battery as possible (within 7 inches is ideal).
The breaker’s amperage rating should match or slightly exceed your motor’s maximum amp draw, as specified in the motor’s manual. This protects your wiring and motor from overcurrents.
3. Run Battery Cables
Route the heavy-gauge battery cables from the battery box to the trolling motor. Use cable ties to secure the cables neatly along the boat’s interior, away from sharp edges, heat sources, and potential pinch points.
Ensure the cables are long enough to reach comfortably without being taut, but not so long that there’s excessive slack. Always use marine-grade tinned copper wire for corrosion resistance.
4. Make Electrical Connections
- Negative (-) Connection: Connect the negative cable from the trolling motor to the negative (-) terminal of your battery.
- Positive (+) Connection: Connect the positive cable from the trolling motor, through the circuit breaker, to the positive (+) terminal of your battery.
For 24V or 36V systems, you’ll need to wire batteries in series. Connect the positive (+) terminal of the first battery to the negative (-) terminal of the second battery. Then connect your motor to the remaining free positive and negative terminals.
Use ring terminals for all battery and motor connections. Crimp them securely and then seal them with heat shrink tubing to prevent corrosion and shorts.
5. Double-Check All Connections
Before connecting the final battery terminal, visually inspect all wiring. Ensure no bare wires are exposed and all connections are tight. A loose connection can cause arcing and heat buildup.
Finally, connect the remaining battery terminal. Your motor is now ready for testing!
First Run and Maintenance Tips
You’ve successfully installed your trolling motor. Now it’s time to test it and learn how to keep it running smoothly.
Initial Test Run
Launch your jon boat in a safe, calm area. Deploy the trolling motor and test all its functions: speed settings, steering (foot pedal or hand control), and any special features like GPS Spot-Lock.
Listen for any unusual noises and check for proper thrust. Ensure the motor deploys and stows easily. Make any necessary adjustments to the motor’s depth or mounting angle.
Routine Maintenance for Longevity
- Clean After Each Use: Rinse the motor with fresh water, especially after use in saltwater, to prevent corrosion.
- Check Propeller: Regularly inspect the propeller for fishing line, weeds, or damage. Remove and clean if necessary. Carry a spare prop and prop nut kit.
- Battery Care: Keep batteries charged and topped off. Check water levels in lead-acid batteries regularly. Store batteries in a cool, dry place during off-season.
- Lubricate Moving Parts: Apply marine-grade grease to any pivot points or steering cables as recommended by the manufacturer.
