Quietly sliding across the water, following the route accurately, and not having the spikes that frighten the fish -- that's what perfect trolling looks like. troll-engine It's becoming the main tool for trophy mining, allowing you to capture large areas of the body of water at a constant speed, and unlike high-speed travel, where maximum power is important, here comes the economy, the ability to work at low speeds and precision control.
The power selection unit depends on many factors: type of boat, size of the reservoir and budget. Some prefer classic gasoline "two-strokes", others unconditionally choose. electric motors Understanding the difference between these types of engines will allow you to avoid buying mistakes and enjoy the process of fishing rather than fighting with machinery.
In this article, we will take a closer look at the technical nuances that beginners often miss, explaining why horsepower is not the only criterion, and how to correctly calculate the necessary traction for your boat + motor + equipment kit.
Gasoline or Electricity: The Battle of Technology
The first and most important question that comes up for the fisherman is the choice of energy source: gasoline-powered internal combustion engines (ICEs) have traditionally dominated large boats and rivers with strong currents, provide high autonomy and do not require recharging, which is critical for multi-day expeditions. noise Vibrations may be undesirable when fishing carefully.
Electric motors (electric vehiculars) provide ideal conditions for trolling. The complete absence of exhaust gases, minimal noise and the ability to instantly stop the propeller make them favorites among spinning riders. Modern models are equipped with lithium batteries that are significantly lighter than lead counterparts and hold the charge longer.
⚠️ Attention: When using an electric motor in salt water, be sure to check for labeling.Saltwater ProoforMarine GradeConventional freshwater models will quickly fail due to corrosion of metal parts of the lower unit.
We compare the main specifications of both types of engines to understand their applicability:
| Characterization | Gasoline engine (2-4 hp) | Electric motor (thrust 30-55 lbs) | Electric motor (thrust 80+ lbs) |
|---|---|---|---|
| Maximum speed | 15-25 km/h | 5-7 km/h | 10-12 km/h |
| Time to work. | 4-8 hours (1 tank) | 2-4 hours (1 ABB) | 4-6 hours (2 ABC) |
| Engine weight | 10-18 kg | 6-10 kg | 20-30 kg |
| Noise at work | Highly | Missing. | Missing. |
Calculation of power and traction effort
Incorrect power calculation is the main reason for disappointment after buying. For gasoline engines, engine size and gear ratio are important, allowing stable operation at low speeds. For electric, the key parameter is traction force, measured in pounds (lbs). One pound of thrust (1 lb) is approximately equal to 0.45 kg of thrust force.This is something that needs to be taken into account when translating values.
There is a simple rule of electric motor selection: for every 45-50 kg of total weight of the boat (hull + engine + battery + fisherman + equipment) 1 pound of thrust is required. If your boat weighs 450 kg in running order, you will need a motor with a thrust of about 55 lbs. Using a too weak motor will cause it to overheat and quickly discharge the battery.
For gasoline units, the optimal range for trolling on PVC boats 3-4 meters long are considered models with a capacity of 2 to 5 hp Motors more powerful than 6 hp often have minimal idling speeds too high, which makes the boat move faster than necessary for wiring the wobblear.
- 🚤 Small boats (up to 3 m): electric motor 30-40 lbs or gasoline 2-3.5 hp
- ⚓ Medium boats (3-5 m): electric motor 50-70 lbs or gasoline 4-6 hp
- 🌊 Large vessels (5+ m): 80+ lbs electric motor (often in conjunction with the main engine) or gasoline 8-10 hp
To accurately calculate the autonomy of the electric motor, multiply the battery capacity (Ah) by voltage (B) and divide by the power consumption of the motor (W) at your operating speed. This will give an approximate run time in hours.
Choice criteria for PVC and metal boats
The hull material dictates its requirements for the attachment and engine type. PVC boats are more sensitive to the vibrations and weight of the transom motor. electric motors with attachment to the transom or on the nose, as they do not create a resonating hum transmitted through the water and board.
Metal boats ("Kazanki", "collar boats") have greater inertia and sailability, for them, a gasoline engine is often a non-alternative option, especially on rivers with the current. However, here the electric vehicle can serve as an excellent aid for quiet approach to the point or maneuvering.
When choosing a mount, consider the design of the transom. Inflatable boats, there are special plates that distribute the load. If you plan to use a heavy battery for an electric motor, it is better to place it on the bottom of the boat in the center or on the nose for balancing, rather than hanging it on a transom to avoid stern.
⚠️ Attention: Do not exceed the maximum recommended power of the motor specified by the boat manufacturer, which can lead to the destruction of the transom and loss of buoyancy at the most inopportune time.
The important aspect is the lower unit. The shallow waters that characterize many fishing areas are the ability to lift the engine. Many modern models have a telescopic leg or a rapid lift system.
Control and navigation systems
Modern trolling is unthinkable without precise course and speed control, basic motor models have simple rumpling control with step-by-step speed switching. digitalization, allowing speed to be set to within tenths of km/h.
The GPS-anchored motors are particularly noteworthy, which allows you to lock the boat at a point and automatically adjust the rotor to compensate for wind or current demolition, and the fisherman can angle without being distracted by oars or rumples.
How does the GPS anchor work?
The system compares the current position of the boat to the given one, and when it moves more than 1 to 2 meters, the motor automatically adds thrust in the right direction, returning the boat to its starting point, requiring an internal or external GPS module.
For integration with sonar and mapplotters, many manufacturers use data exchange protocols, such as: NMEA 2000 or proprietary networks (e.g., i-Pilot Link Minn Kota or Ghost This allows you to control the motor directly from the navigator screen, paving the trolling routes.
- 📡 Remote control: The presence of a foot pedal or key fob significantly increases comfort.
- 🔄 Reverse: It is smooth and powerful, necessary for maneuvers in thickets.
- 💡 Indication: Displaying the battery residue (discharge indicator) is critical.
Maintenance and extension of the resource
Even the most reliable troll-engine In the case of electric motors, the main enemy is the water inside the hull and the oxidation of contacts, and after every fishing trip, especially in salt water, you need to rinse the lower unit with fresh water.
Low-power gasoline engines are often two-stroke and require a mixture of fuel. Using poor-quality oil or old gasoline leads to candles and a piston group. For four-stroke analogues, it is important to regularly change the oil in the gearbox and check the level in the crankcase.
☑️ Seasonal engine maintenance
Battery storage is a separate topic. Lithium batteries can be stored on a partial charge, but lead-acid (AGM, GEL) batteries need to be recharged, otherwise they will lose capacity in one winter. Use automatic chargers with desulphation mode.
Top models and manufacturers in the market
The trolling motor market is divided among several major players, and the American company is already the leader in the electric motor segment. Minn KotaTheir series. Endura (budgetary) and Ulterra (top GPS) set the standards for reliability.
The brand is not far behind. MotorGuideBrunswick's servo motors. Xi5 They're famous for their quiet operation and smoothness. Yamaha and Tohatsu2-4 strong models are distinguished by enviable survivability.
Chinese manufacturers, such as Hangkai or WatersnakeThey offer more affordable alternatives, and their products have grown in quality, and they can be great for amateur use, but they don't have to be GPS anchored or 10 years of service without repair.
When choosing between a brand and a price for professional trolling, it is better to overpay for a proven brand – reliability and the availability of spare parts are more important than saving money during active fishing.
⚠️ Attention: Buying engines of little-known brands, immediately purchase a set of spare gears for the gearbox and glands. They often do not have a repair base, and you will have to repair yourself.
FAQ: Frequently asked questions
How long does the electric motor last on a single charge?
The battery life depends on the battery capacity (Ah) and the speed chosen. At an average speed (50% of the power), a 100 Ah battery will provide approximately 3-4 hours of operation. At a minimum speed, the time can reach 8-10 hours.
Can I use a car battery for a outboard motor?
It's not recommended. Car starter batteries (Starters) are not designed to deliver low-power current for long periods of time. They degrade quickly. Boats need Deep Cycles like AGM or GEL.
What is the best speed for trolling?
The optimal wiring speed depends on the predator and bait, but usually ranges from 2 to 5 km / h For pike and perch is often more efficient slow wiring about 3 km / h, for perch speed can be increased.
Do I need to register a outboard motor in GIMS?
Registration is required for motors over 8 kW (approximately 10.8 hp). All engines for trolling (usually up to 5-6 hp) do not require registration, but the boat itself must be registered if its mass with the engine exceeds 200 kg.
