Finding the perfect power plant for slow but steady movement on the water is a challenge that every passionate spinner faces. Which motor is better for trolling?It has been a long way since the advent of specialized traction motors, which have dramatically changed the way we hunt predators, and unlike gasoline-powered vehicles, they provide noiselessness, no vibrations, and the ability to accurately control speed, which is critical to presenting bait.
But the variety of models on the market today can baffle even the experienced water-engineer, from low-end Chinese models to premium GPS-anchored systems, the range of performance is huge, and a mistake in choosing can cost not only money, but also lost fish. In this article, we will discuss the key parameters that allow you to choose the optimal traction for your boat and fishing conditions.
Before going into the technical specifications, it is worth noting that electromotor It's always a trade-off between weight, range and cost, and a properly selected unit makes fishing fun, allowing you to spend hours catching promising catches without the roar of the engine or the smell of gasoline, and let's figure out what to look for first.
Key specifications: traction and voltage
The first thing that an angler looks at when choosing is the maximum thrust, measured in pounds (lbs), but you shouldn't blindly believe the numbers on the box, because you can't believe them. traction Most low-power models run at 12 volts, while more serious units require 24 or even 36 volts. The higher the voltage, the more efficient the engine is at the same current, which reduces wire heating and increases efficiency.
It is important to understand that the claimed thrust of 55 lbs (about 25 kg) does not mean that the motor will be able to push a boat weighing 25 kg with full load. This is the force that the propeller develops in static or at minimum speed. For comfortable trolling on a PVC boat with a length of 3.2-3.6 meters, 40-55 lbs is usually enough. Minn Kota or MotorGuide On a metal or heavy boat, it is worth thinking about models with thrust from 70 lbs and above.
Choosing a voltage system is a strategic decision. Going 24 volts requires two series-connected batteries, which increases the weight and overall compartment. However, for large bodies of water that require a 6-8 hour range of active operation, this is often the only way to go. On small rivers and lakes, the 12-volt system remains the de facto standard because of its simplicity and affordability.
Types of fastening and construction of lower unit
The design of the motor mount determines not only the ease of installation, but also the versatility of use. There are three main types: transom, nose and suspension (for mounting on a ramp or in a hole in the floor). transmutationThey're very fast to put and remove without drilling the hull of the boat, and they're ideal for PVC boats, where every extra weight and every hole counts.
The bow mount, although considered a more professional solution for larger boats, often poses balancing problems on small vessels. However, such systems have the advantage of having a longer control humming device and being able to stand in the center of the boat, controlling the course. The lower unit (foot) of the motor also plays a role: telescopic models allow for the depth of the propeller to be adjusted, which is relevant for shallow waters where the risk of hook is high.
⚠️ Note: When installing the motor on the transom of PVC boats, be sure to use a protective lining or a special board. Direct contact of the metal bracket with the balloon during rolling can lead to scuffing and even puncture of the material.
The lower unit material is also important: Aluminum bars are lightweight, but they're afraid of hitting rocks. The composite materials used in top-end models are very tough and flexible, quenching vibrations. composite This will be the best investment in the durability of the equipment.
Screws: number of blades and step
The screw is the workhorse of any jet or rowing device, and in electric motors, it plays a crucial role in the efficiency of trolling. double-bladeIt creates less drag when you spin, which saves battery power, and it provides enough thrust at low rpm. It's good enough for glides of light boats.
Three-bladed screws, such as Weedless Wedge 2 Minn Kota, which is designed for challenging environments, they hold water better, they create more even traction, they're less prone to cavitation, but their main advantage is that they have increased cross-country ability, and the blades are designed to grind algae without winding them onto a shaft, which is critical for overgrown bay fishing.
There are also adjustable pitch propellers, although they are rare in the electric motor segment. Most anglers are limited to standard plastic or composite models. Always have a spare propeller on board.
- 🌊 The two-bladed propeller is a classic for clean water and planing light boats.
- 🌿 Three-bladed screw is the choice for overgrown ponds and heavy loading.
- ⚓ A propeller with a high thrust - for boats with a flat bottom and a large resistance.
Control and electronics systems
The modern electric motor is a complex electronic-mechanical complex, with basic models featuring a step-by-step speed adjustment (usually 5 forward and 3 backwards) that is reliable and time-tested, where switching is done mechanically or through simple electronic keys. step-adjustment It is very convenient: you choose speed and you swim.
More advanced systems offer smooth (stageless) speed adjustments, often with a pedal-leg or wireless remote. The pedal allows the angler to keep his hands free for spinning, instantly responding to changing situations. Having a digital display showing the battery's remaining battery charge in percentage and current speed greatly improves fishing comfort, eliminating the "sufficient energy to shore" guess.
The pinnacle of evolution is the GPS-anchor motors (i-Pilot, Ghost and analogues), which remember a point and automatically hold the boat within a radius of 1.5-2 meters, despite the wind and current. trolling revolutionIt allows you to perfectly walk the same line ("track") many times, but the cost of such systems can be several times higher than the cost of the engine itself.
⚠️ Attention: Motor electronics are sensitive to voltage drops. Do not allow a deep discharge of the traction battery below 10.5 volts (for 12V systems), as this can lead to incorrect operation of the controller or loss of settings.
Battery base and calculation of autonomy
The heart of any electric traction is the battery, and trolling is not the way to do the starter car batteries, which are designed to give you a short-term return of huge current. traction Deep Cycle, which can deliver low-current long-terms and withstand hundreds of charge-discharge cycles, is the most popular technology, GEL, AGM and, gaining momentum, LiFePO4 (lithium-iron-phosphate).
Calculating the operating time is a mathematical problem. The engine consumption depends on the load. At a minimum speed, a 12-volt motor can consume 5-7 Amps, at a maximum it can consume up to 50 Amps and above. Watersnake or Haswing You need to know the battery capacity in the Ampere watch (Ah).
Use the formula: Time (hours) = (Battle Capacity × 0.8) / Current consumption. coefficient 0.8 takes into account losses and the recommendation not to discharge the lead battery by more than 20%.
Lithium batteries (LiFePO4) weigh 3 times less than lead at the same capacity and give current more stable until the very end of the discharge. Their only disadvantage is the high initial price, which, however, pays off in service life (2000+ cycles versus 300-500 for lead). The most effective way to reduce the weight of the boat without losing a power reserve.
Comparative table of popular models
To organize the information, consider the comparative specifications of several popular models on the market, the data may vary depending on the specific modification and year of release, but give an overview of the class of devices.
| Model | Max. traction (lbs) | Voltage (B) | Weight (kg) | Features |
|---|---|---|---|---|
| Minnta Kota Endura C2 30 | 30 | 12 | ~7.5 | Budget, 5 speeds |
| Watersnake ASP T18 | 18 | 12 | ~5.5 | Superlight, for small boats |
| MotorGuide Xi3 55 FW | 55 | 12 | ~17 | Wireless control, GPS-ready |
| Haswing Cayman B 55 | 55 | 12 | ~16 | Telescopic leg, pedal complete |
| Ninfa 46 (China) | 46 | 12 | ~8.0 | Affordable price, basic functionality |
And you can see from the table that the weight spread at similar thrust can be double, and that has a direct impact on the stability of the boat. A heavy motor on the transom of a small PVC boat can require a transfer of passengers or a shift of cargo to compensate for the gap. WatersnakeThey are often chosen for their mobility.
Service and extension
Electric motors require minimal but regular maintenance, and the main problem is corrosion and water intake, even models with declared protection. IP67 After every fishing trip, especially in salt water, the motor must be rinsed with fresh water, and the salt coating corrodes the metal and oxidizes the contacts faster than any other medium.
☑️ Annual Electric Motor Vehicle
Special attention should be paid to the omentums. They are located on the shaft and protect the inside of the engine from water. If you notice that an emulsion (white porridge) has appeared in the lower gearbox, then the omentum is leaking water. It is forbidden to operate such a motor, it will lead to corrosion of the windings and expensive repairs.
⚠️ Warning: Never keep the motor compressed (folded) for a long time. the spring of the lifting mechanism may become tired and the motor will stop fixating in the operating position, which is dangerous when driving.
Battery storage is also critical. Leaving a lead battery dead for the winter is a sure way to send it to recycling. Be sure to put the battery on a conservation charge. Lithium batteries are more loyal in this regard, but it is recommended to store them with a charge of 50-70% at plus temperature.
Final choice: balance of price and quality
The answer to the question, "What's the best engine?" is always personal. For a 320 cm inflatable boat owner who fishes 5-10 times a season on a small lake, it makes no sense to overpay for GPS systems and lithium. He's perfect for a simple 12-volt 30-40 lbs motor and an AGM battery. middle-of-the-road price and reliability.
For an athlete or fan who spends 100+ hours on the water, investing in a 24-volt system with lithium battery and telemetry will pay off with comfort and catches. Being able to anchor in the middle of a river and safely catch a dot without throwing a real anchor or motor noise changes the very philosophy of fishing.
The best trolling motor is the one that matches the weight of your boat, has a 20-30% thrust reserve and is equipped with a battery that provides a minimum of 4-5 hours of travel at medium speeds.
Don't chase for maximum power. Excessive traction on a small boat will only lead to fast battery discharge and uncomfortable handling at low speeds. Soberly assess your needs, check the compatibility of the mounts and enjoy the quiet water where you can hear only the splash of fish and the rustle of the wind.
Can an electric motor be used for planing?
Theoretically, yes, if the engine power (in hp equivalent) is about 1/10th the weight of a load boat and the propeller has a large pitch. However, electric motors are designed for low-speed traction. Prolonged plane drains the battery quickly (in 15-20 minutes) and can overheat windings that are not designed for such currents.
Which battery is better: GEL or AGM?
They are cheaper, better able to carry charge with high currents and less sensitive to temperature changes. GEL batteries are afraid of overcharging (boiling and swelling) and require special chargers, making them less versatile for the average angler.
Why is the engine buzzing or vibrating?
The main causes: winding of the line or grass on the screw, damage to the propeller blades, wear of the shaft bearings or violation of centering. Also vibration can occur if the motor is not sufficiently immersed in water and captures air (cavitation).
Do I need to lubricate the electric motor?
Yes, but only certain components, and regular lubrication is required by movable rod joints, clip threads and, when maintained, bearings, and the internal gearbox is lubricated with a special, consistent lubricant when replacing the omentums, usually once a season or two.
