Inflatable kayaking is the perfect trade-off between mobility, ease of transportation and functionality on the water, but rowing long distances or against the current and wind can turn a pleasant walk into a grueling marathon that requires considerable physical effort. kayakerIt can radically change your idea of the possibilities of a light inflatable boat.
Using electric propulsion not only saves energy, but also sneaks up silently to fish places, shy birds or just enjoy the silence of nature without a rhythmic burst of oars. Modern technology has made these devices compact and lightweight, which is completely consistent with the philosophy of using inflatable watercraft, where every kilogram of weight counts.
In this article, we will discuss in detail how to choose the optimal model, what are the nuances of mounting on the soft side and how to properly operate the battery so that your launch passed without technical surprises. You will learn about the key specifications that should be paid first of all, so as not to overpay for unnecessary functions or, conversely, not to purchase a too weak device.
Key criteria for choosing an electric motor for an inflatable boat
The first thing that a buyer encounters is a huge range of specifications and prices. engine-powerFor a light kayak with one fisherman and minimal gear, a 30-40 lbs model is usually enough. If you plan to take a passenger, a heavy anchor, sonar and spare batteries with you, you should consider options with thrust up to 55-60 lbs.
The second critical aspect is the length of the lower unit (legs). Because kayaks are low-sided, standard boat legs can be too long, which will lead to excessive diving of the screw and creating excessive resistance. The optimal solution is short-dadewood models, often labeled "Short Shaft" or specially designed for kayaks. The screw must be 15-20 cm underwater for effective operation.
You also have to look at the mounting system, and inflatable vessels are the ideal option. transom-holding It has a wide clamping pad that doesn't hurt the cylinders, and some models have universal brackets that allow you to attach the motor directly to the seat or to a special platform, and the weight of the motor itself also plays a role: composite models are lighter than metal ones, which is important when carrying the motor manually.
And don't forget the control system. The control tube is very maneuverable, but it takes one hand. If you often go fishing alone, it makes sense to look at the models that you can install. foot-control or even remote control, although the latter are less common in the budget segment.
Features of the installation of the motor on an inflatable kayak
Soft-board electric motors require a different approach than an aluminum boat on a hard transom, and the main task is to spread the load so that the motor doesn't push through the cylinders and move sideways when you're driving. transmutor or a special motor console, which is attached by slings to the switches or handles.
When installing, make sure all points of contact between the motor and the boat are protected from friction. Use dense fabric, special PVC linings or just old towels in places where metal parts of the bracket can touch inflatable tubes. Vibration of the working screw can quickly wipe even durable material if you do not take precautions.
⚠️ Warning: Never attach the motor directly to a thin bottom stringer or a weak part of the cylinder without a reinforcing plate.
Centering is also crucial: If the motor is placed too far into the nose or stern, the kayak will start to prowl or, conversely, burrow its nose into the wave. The ideal position is when the lower unit is about 20-30 cm from the cut of the transom (or imaginary line of the transom), and the screw is submerged in water at the mark on the leg.
☑️ Check before the first launch
There is an alternative method of mounting on the suspended seat, which is only suitable for very light motors (up to 3-4 kg) and short distances, in which case the seat should be rigidly fixed and the engine pointed strictly backward, but this method is less stable and is not recommended for windy weather.
Comparison of popular models of electric motors
The market offers a variety of options, from budget Chinese brands to eminent European manufacturers, and to make it easier to choose, we compared several popular models that are often considered by kayakers. nominal It may differ from the real one on water due to the shape of the screw and the quality of the assembly.
| Model | Traction (lbs) | Weight (kg) | Features |
|---|---|---|---|
| Haswing Cayman B | 40-55 | 7.5 - 9.0 | Telescopic handle-pump, quiet stroke |
| Min Kota Endura C2 | 30-40 | 7.0 - 8.0 | A classic, time-tested, easy to find parts |
| Waterman | 36-46 | 6.5 - 7.5 | Budget segment, good price/quality ratio |
| Ninety One | 36 | 6.8 | Compact, rotating mechanism at 360 degrees |
Model series Haswing Often chosen for ergonomics: the ability to fold the tiller makes them transported in the trunk of a car much more convenient. Min Kota It's famous for its reliability and durability, although it's more expensive. Waterman or Ninety One It is perfect for beginners who want to try an electric vehicle without serious investments.
The secret to the durability of the screw
Composite screws (plastic) will simply break or chip when hit by a rock or a snag, keeping the motor shaft intact. Metal screws can bend a lower unit when impacted, which will be very expensive to repair. For shallow water and stones, plastic is preferable.
When you choose, you also look at the speed count, usually five forwards and two or three backwards, and having a smooth speed adjustment (at least on some models) allows you to more accurately select your driving mode, saving battery power.
Battery: The Heart of Your System
The motor itself, without a power source, is just a piece of metal and plastic. tractionThese are different from car starter batteries, which can give off energy in small portions for a long time, but it is possible to use a conventional car battery, but it is not recommended, since it will quickly fail at deep discharges.
The most popular lead-acid batteries, such as AGM or GEL, are 55 to 100 Ah. They are heavy (15-30 kg), but affordable. Lithium-Iron-Phosphate (LiFePO4) They're 2-3 times lighter than lead, have more charge-discharge cycles, and are not afraid of deep discharge, but they cost a lot more.
The calculation of the running time is simple: if you have a 50 Ah battery and the engine consumes 20 Amps at maximum speed, then theoretically it will last 2.5 hours. However, in practice, given the losses and the prohibition on full discharge, the time will be shorter. So always take the battery with a margin of capacity.
Charge the battery immediately after each fishing trip, even if you've been riding for only an hour. Left dead, the lead battery quickly sulfates and loses capacity irrevocably.
Don't forget to buy a high-quality charger with automatic shutdown. "Boiling" electrolyte is bad for the battery. Also for safety and convenience, you should get a sealed battery box with a carry handle that will protect the battery from splashes and impacts on the side of the kayak.
Rules of operation and care of electric motor
To make the electric motor last long and enjoy stable operation, you need to follow a number of simple but important rules of operation: fresh water is not as aggressive as sea water, but it can cause corrosion of metal parts if you leave the motor assembled for a long time.
After each outing, especially if you have been swimming in a salty pond, rinse the lower unit and screw with fresh water. Periodically (once a season or every 20-30 hours) it is recommended to lubricate the glands and moving parts with a special lubricant resistant to water, this will prevent moisture from entering the gearbox.
- 🌊 Always check the screw for the absence of coiled grass or fishing line before starting - this will save the glands from overheating.
- 🔋 Do not keep the battery completely discharged in winter, this is guaranteed to put it out of action.
- ⚙️ Regularly check the tightening of fasteners, as the vibration has the property of unwinding them.
⚠️ Warning: Never run the motor out of water ("dry") for more than a few seconds to check. Lack of water cooling can cause the osteoils to overheat and damage, which will lead to water entering the engine.
Keep the motor disassembled or upright so that the oil in the gearbox does not leak out through the glands. Pack the device into a case to protect the plastic from ultraviolet light, which makes the materials brittle.
Advantages and Limitations of Electric Rover on a Kayak
The switch to electric propulsion opens up new horizons for inflatable boat owners, allowing you to travel 10 to 20 kilometers per exit without physical fatigue, which used to be the case only for heavy PVC boats with gasoline engines, and it changes the geography of your travels, making available remote stretches of rivers and lakes.
But electric motors have their limitations, and the main one is the dependence on battery capacity and the inability to quickly refuel far from civilization. If a gasoline engine can be refueled from a canister in a minute, then a dead battery will require a replacement or a long charge from the generator, so planning a route with a reserve becomes a must.
In addition, electric motors are sensitive to high winds and high waves. A light kayak with a low profile under the influence of the wind becomes a sail, and the power of 30-40 lbs may not be enough for confident movement against a storm. In such conditions, the electric vehicle is good as an auxiliary tool, but not as the only traction force.
The electric motor turns the kayak from a sports projectile into a full-fledged tourist vessel, allowing you to combine rowing and motor stroke for maximum distance coverage.
But the silence of an electric motor is a trump card: you don't scare the fish away with the roar of the motor, you don't scare the wildlife, and you can hear the splash of fish or the cries of birds, which is the number one priority for many fishermen and naturalists.
Frequently Asked Questions (FAQ)
Can you use an electric motor on a kayak without a hard transistor?
Yes, it is possible. There are special attachments (outriggers or transom adapters) that are attached with belts to the switches, handles or sides of the kayaking, the main thing is to ensure that the structure is rigid so that the motor does not dangle and damage the inflatable elements.
Which battery is better to choose for a beginner: lead or lithium?
For a beginner who wants to try an electric vehicle at minimal cost, a 55-65 Ah lead-acid AGM battery is suitable. It is heavier, but cheaper. If the budget allows and every kilogram of weight is important, you should immediately look at LiFePO4 batteries, which are lighter and last 5-10 times longer.
Will a kayak with an electric motor develop a speed above 10 km / h?
The body of the kayaking boat and the shape of its nose are not designed to plane. Even with a powerful motor, the speed rarely exceeds 6-8 km / h due to the high resistance of the water and the shape of the boat. The electric motor is not for speed, but for comfortable movement at a cruising speed of 4-5 km / h without effort.
Do I need to register a kayak with an electric motor in GIMS?
Under current Russian law, vessels weighing more than 200 kg or with an engine power of more than 8 kW (about 10.8 hp) are subject to registration. Electric kayaking motors have a power of about 0.5-1 kW, which is well below the registration threshold. However, the weight of a curb kayaking with a motor and battery must be less than 200 kg, which is usually observed. Always clarify the current rules, as they may change.
How to transport an electric motor in a car?
Most kayaking motors are telescopic or collapsible, Dadwood folds or unscrews, and it can easily fit in the trunk of a compact car, especially if you take it off the transom plate, and it's recommended to carry it in a case or box so that you don't get any water or lubricant left over.
