Trolling motors provide an efficient, quiet way to power your kayak—ideal for covering longer distances or simply conserving energy on the water. But how fast can a kayak actually go with a trolling motor? Generally, speeds range from 2 to 6 mph, depending on the motor’s thrust, battery type, kayak weight, and water conditions.
This article explores how trolling motors work on motorised kayaks, the key factors that affect speed, and how to choose the best marine battery to match your setup.
A motorised kayak is a standard kayak outfitted with either an electric or petrol-powered motor. It allows you to travel further and faster than with paddling alone, offering convenience and versatility for fishing, touring, or leisure trips.
Trolling Motor – Usually electric, mounted at the stern or bow.
Battery – Powers the motor (commonly a 12V deep cycle battery).
Mounting System – Secures the motor to the kayak.
Most kayak enthusiasts prefer electric trolling motors due to their quiet operation, lower weight, and ease of use. In contrast, petrol motors offer more power but are heavier, noisier, and less commonly used on kayaks due to their bulk.
Trolling motors convert energy from a battery into mechanical power, which spins a propeller to move the kayak through the water. The process depends heavily on the efficiency of the motor and the capacity of the battery.
Electric Motor & Propeller – Generates thrust to propel the kayak.
Battery Power – Supplies sustained energy; lithium or lead-acid types are common.
Calm waters and tailwinds boost speed.
Headwinds and currents reduce speed.
Light, narrow kayaks require less thrust and go faster.
Wider, heavier models need more power to maintain speed.
A higher thrust motor provides more force—but drains the battery faster.
Larger batteries (higher Ah ratings) allow for longer runtime and more consistent speeds.
E.g., a 100Ah battery could last all day under moderate use, while a 50Ah battery suits shorter 2–4 hour trips.
| Motor Thrust | Estimated Speed (mph) | Best For |
|---|---|---|
| 30–40 lbs | 2–3 mph | Small kayaks (<12 ft) |
| 40–55 lbs | 3–4 mph | Medium kayaks (12–14 ft) |
| 55–80 lbs | 4–6 mph | Large kayaks (>14 ft) |
2 to 2.4 lbs of thrust per 100 lbs of total kayak weight.
So, for a 150 lb kayak with gear and person, a 30–40 lb thrust motor will work well in calm water.
20–30 lbs Thrust → 12V, 35–60Ah battery
30–70 lbs Thrust → 12V, 60–100Ah battery
70–100 lbs Thrust → 24V system (2x 12V or 1x 24V lithium battery, 80–100Ah)
100+ lbs Thrust → 36V system (3x 12V or 1x 36V lithium battery)
Longer lifespan – 4000+ cycles at 100% DoD
Lightweight – Up to 70% lighter than lead-acid
Stable performance – Holds voltage better
Lower total cost of ownership
Example: EVLithium’s 12V LiFePO4 battery lasts up to 10 years, making it a superior investment over time.
Typically 3–4 mph on small to medium-sized kayaks in calm conditions.
Approximately 4–5 mph, depending on kayak weight and wind/water resistance.
Up to 2000 lbs in weight—suitable for small fishing boats, jon boats, or motorised kayaks.
Yes—especially if you’re covering long distances, fishing, or want to reduce physical exertion. It offers convenience, comfort, and extended range.
A trolling motor can significantly enhance your kayaking experience by allowing you to cruise at 2–6 mph without paddling fatigue. When paired with a quality LiFePO4 lithium battery, your motorised kayak becomes a highly efficient, long-lasting vessel for fishing or recreational adventures. Choose the right motor thrust and battery size based on your kayak’s weight and your intended trip duration to get the best results on the water.
