Chapter 17: The Buy with Confidence Checklist

Congratulations—you've reached the final chapter.

By now, you understand how trolling motors work, how to choose the correct thrust, voltage, shaft length, batteries, electronics, and supporting equipment.

Before making your purchase, use this final checklist to confirm every important decision.

A trolling motor is not simply another accessory. It is part of a complete system that affects boat control, fishing efficiency, battery performance, electronics integration, and your overall experience on the water.

Taking a few minutes to review each decision before purchasing can prevent installation problems, unexpected costs, and performance disappointments later.

If you can confidently answer “yes” to every question in this chapter, you are well prepared to invest in a trolling motor system that should provide years of dependable service.

1. Is the Motor Designed for Your Boat Type?

Begin with the boat itself.

Confirm that the trolling motor is appropriate for your:

• Boat length
• Loaded weight
• Hull design
• Bow height
• Mounting location
• Typical passenger load
• Fishing environment

A motor that performs perfectly on a bass boat may not be suitable for a high-bow center console. Likewise, a heavy 36V system may be unnecessary for a lightweight aluminum boat or fishing kayak.

Confirm Your Boat Category

Your setup should make sense for the type of boat you own:

Boat Type	Common Setup Direction
Fishing kayak	Compact 12V or kayak-specific motor
Jon boat	12V or 24V transom or bow mount
Bass boat	24V or 36V GPS bow mount
Multi-species boat	24V or 36V GPS bow mount
Flats boat	Lightweight saltwater bow mount
Bay boat	High-thrust saltwater GPS motor
Offshore center console	Long-shaft 36V saltwater GPS motor

These are starting points rather than fixed rules. Your fully loaded weight and fishing conditions should always guide the final decision.

Final Check

✔ Is the motor designed for your boat type?

✔ Is your deck suitable for the intended mounting system?

✔ Will the motor deploy and stow without interference?

✔ Is there enough room for the batteries, charger, wiring, and accessories?

2. Is the Thrust Appropriate for Your Boat?

Thrust determines how effectively the trolling motor can move, steer, and hold your boat.

Choose thrust based on the boat's actual operating weight—not only the manufacturer's dry hull weight.

Include:

• Outboard engine
• Fuel
• Batteries
• Passengers
• Fishing gear
• Livewell water
• Coolers
• Anchors
• Electronics
• Safety equipment
• Added accessories

A motor that seems adequate for an empty boat may struggle once the boat is fully loaded.

Consider the Conditions

Your thrust requirements increase when fishing in:

• Heavy wind
• Strong river current
• Tidal flow
• Rough water
• Offshore conditions
• Thick vegetation

A reasonable amount of reserve power improves control and allows the motor to work without operating at maximum output all day.

However, buying far more thrust than you need can increase cost, battery requirements, system weight, and installation complexity.

Final Check

✔ Is the thrust appropriate for your fully loaded boat?

✔ Have you accounted for wind and current?

✔ Will the motor provide enough reserve power for difficult conditions?

✔ Are you comfortable with the voltage and battery requirements that come with that thrust level?

3. Have You Measured for the Correct Shaft Length?

Shaft length is one of the most important—and most frequently misunderstood—trolling motor specifications.

The propeller must remain properly submerged while the boat moves through waves, wind, and changing passenger loads.

If the Shaft Is Too Short

You may experience:

• Propeller ventilation
• Loss of thrust
• Excessive noise
• Inconsistent steering
• Poor GPS anchoring
• Reduced control in rough water

If the Shaft Is Too Long

You may encounter:

• Difficult stowing
• Unnecessary weight
• Storage interference
• Excessive shaft extending above the mount
• Greater risk of impact in shallow water

Do not select shaft length based only on boat length. Measure from the intended mounting surface to the waterline and account for the conditions in which the boat will be used.

High-bow and offshore boats usually require considerably longer shafts than low-profile bass boats or jon boats.

Final Check

✔ Have you measured from the mounting surface to the waterline?

✔ Have you accounted for bow rise and wave action?

✔ Will the propeller remain submerged when passengers move around the boat?

✔ Will the motor stow securely without interfering with rails, cleats, electronics, or covers?

4. Does the Voltage Match Your Performance Expectations?

Trolling motors commonly operate on 12V, 24V, or 36V systems.

Voltage affects:

• Available thrust
• Runtime
• Electrical efficiency
• Number of batteries
• Charger requirements
• Weight
• Installation cost

12V Systems

Often best for:

• Kayaks
• Small jon boats
• Lightweight skiffs
• Occasional use
• Portable installations

24V Systems

Often best for:

• Medium-size fishing boats
• Bass boats
• Multi-species boats
• Larger aluminum boats
• Moderate wind and current

36V Systems

Often best for:

• Heavy bass boats
• Bay boats
• Offshore center consoles
• Large multi-species boats
• Long fishing days
• Demanding GPS anchoring

Higher voltage is not automatically better. It is better only when the boat and fishing conditions justify the additional batteries, weight, charger capacity, and expense.

Final Check

✔ Does the motor's voltage match the boat's size and weight?

✔ Do you have enough room for the required batteries?

✔ Can the boat safely carry the added battery weight?

✔ Is the wiring designed for the voltage and current requirements?

✔ Does the charger support the complete battery bank?

5. Have You Selected the Right Batteries?

The battery system directly affects runtime, thrust consistency, charging time, and long-term ownership cost.

Choose batteries based on:

• Motor voltage
• Amp-hour capacity
• Battery chemistry
• Available storage space
• Boat weight
• Expected fishing duration
• Typical power demand
• Charging schedule

AGM Batteries

AGM batteries remain a strong choice for many anglers.

Advantages include:

• Lower upfront price
• Proven reliability
• Broad charger compatibility
• Simple replacement

Considerations include:

• Greater weight

6. Is the Charger Compatible?

An onboard charger is an essential part of the system, not an afterthought.

The charger should match:

• Battery chemistry
• Number of batteries
• Battery-bank configuration
• Charging-current recommendations
• Available recovery time between trips

A 24V system using two 12V batteries will typically need a two-bank charger. A 36V system using three 12V batteries will generally require three charging banks.

You may need an additional charging bank for the boat's starting or electronics battery.

Confirm the Charging Profile

Make sure the charger supports:

• Flooded lead-acid, if applicable
• AGM
• Lithium iron phosphate
• Any manufacturer-specific requirements

Using an incorrect charging profile can lead to incomplete charging, reduced battery life, fault warnings, or battery damage.

Final Check

✔ Does the charger support your battery chemistry?

✔ Is there one charging bank for each battery that requires independent charging?

✔ Is the charger output appropriate for the battery capacity?

✔ Can the system recharge fully before your next trip?

✔ Is the charger mounted in a suitable, ventilated location?

7. Will the Electronics Integrate Properly?
