Choice electric motor For an inflatable vessel, it's often a turning point for a fisherman or a water-spoken enthusiast, and many people switch from gasoline to electric, looking for quiet, saving and sustainability, but they're faced with a lot of conflicting information, and the market is full of models from Chinese manufacturers to expensive American brands, and it's hard to understand marketing and real-world specifications without experience.
In this article, we analyzed hundreds of real-world review So you can get an objective picture of the owners, and you can learn about the real-time battery life, the saline water environment, and the little things that are not talked about in the stores. Plunge Speed is not the only thing you should pay attention to when buying.
Before we dive into the details of the reviews, it's important to note that there is no perfect motor. Each model is designed for specific tasks, whether it's a high-speed passage through shallow water or a long-duration drive. trolling Understanding your needs will save you money and nerves.
Why owners choose electric traction for PVC boats
The main reason for the switch to electricity users in their comments called the complete absence of vibration and the smell of gasoline. PVCAny noise is transmitted through the water and body, scaring the fish. The electric motor operates almost silently, which is critical for hunting a cautious predator.
The second important aspect is ease of maintenance, because unlike the ICE, there are no candles, filters, or oil, but that doesn't mean there are no weaknesses. Tightness lower unit and the quality of bearing lubrication – that’s what users of budget segments complain after intensive operation.
⚠️ Attention: Cheap models often have plastic gears in a gearbox that may not withstand a hit on a rock or a snag. When buying, check the gear material.
Also worth mentioning is the environmental friendliness and the possibility of using in no-gasoline zones, and in many nature reserves and in urban water bodies only allowed. motor-powerThis opens up new horizons for fishing in places where it used to be noisy and forbidden.
Real specifications: traction and speed according to reviews
Manufacturers often specify maximum thrust under ideal conditions, but reality makes its own adjustments: owners of boats 3-3.5 meters long with full gear note that the motor with a declared thrust of 30 lbs (pounds) barely accelerates the vessel to 5-6 km / h. For comfortable fishing, this can be little if there is a headwind or current.
For PVC boats with a length of more than 3.6 meters, experts and experienced users recommend looking towards models with thrust from 40-50 lbs. Power reserve is necessary not so much for speed, but for confident overcoming the excitement and maintaining battery power. Engine efficiency It falls when working at the limit of possibilities.
The table below compares the average speeds for different thrust classes on a standard PVC boat of 3.2 meters with one fisherman:
| Traction class (lbs) | Real speed (km/h) | Recommended weight of the boat | Current consumption (A) |
|---|---|---|---|
| 30 lbs | 4.5 - 5.5 | 600 kg | 12 - 15 |
| 40 lbs | 5.5 - 6.5 | 900 kg | 18 - 22 |
| 50 lbs | 6.0 - 7.0 | 1200 kg | 25 - 30 |
| 55+ lbs | 7.0 - 8.0 | over 1,200 kg | 35 - 45 |
It's important to understand that the shape of the screw and its pitch also affect the final speed, and some users are experimenting with replacing regular screws with more aggressive ones, getting a speed gain of 0.5-1 km / h, but losing battery life.
To increase speed in shallow water, use smaller diameter screws, but remember that this will reduce efficiency in deep water.
The problem of autonomy: batteries and operating time
The most common source of negative feedback is the mismatch of the stated time of operation of reality. If a manufacturer writes "up to 6 hours", this often means moving at a minimum speed at a calm, real fishing with constant transitions and working against the current reduces this time by 2-3 times.
The key factor here is the type of battery. acidic (GEL, AGM) Batteries are heavier and fear deep discharge, which shortens their lifespan. LiFePO4 batteries that are 2-3 times lighter and give away almost 100% of their capacity without harm to chemistry.
- 🔋 AGM/GEL: Cheaper, heavier, can not discharge below 50-60%, the service life of 300-500 cycles.
- 🔋 LiFePO4: Expensive when buying, very light, discharge up to 80-90%, service life of 2000+ cycles.
- 🔋 Starter ABC: They are not suitable for long-term work, they quickly deteriorate.
Calculating battery capacity is a math that can't be ignored. If your motor consumes 20 Amps at average speed, then a 100 Ah battery (actually usable about 60-80 AH for acid) will provide about 3-4 hours of travel. A full day of fishing requires a stock or a second battery.
☑️ Checking before getting on the water
Overview of popular brands: Minn Kota, Motorum, HDX
The market leader has been the American brand for decades. Minn KotaThey're all different, and they're a benchmark for reliability and spare parts, and they're also a high price tag and a lot of failures in budget lines assembled in Asia. CoolPower and the reliability of the attachment.
Chinese brands such as Motorum and HDXThe price of one Minn Cat can buy three Chinese, and the reviews say that for their money they work perfectly, but the materials (plastic, paint) are inferior to the top models. After 2-3 seasons of active use, often require bulkheading gear or replacement of oils.
⚠️ Warning: When buying budget models, check for the presence of glands on the shaft immediately. Often they are installed poorly, which leads to water entering the inside of the lower unit.
And we should also mention Russian assemblies with Chinese components, which are often adapted to our conditions: thicker cables, reinforced mounts. Warranty services In the case of such brands, it is easier to find than for gray imports.
The secret of the durability of Chinese engines
Immediately after purchase, replace the standard lubricant in the gearbox with a quality water-resistant lubricant (for example, Lithium Complex).
Nuances of operation in salt water
Using an electric motor in the sea or in salt lakes is extreme, even models labeled "Saltwater" require careful care, and the main enemy is corrosion of aluminum lower unit and oxidation of contacts.
Owners who ignore freshwater washing after each exit face problems after 10 to 15 hours of winding, and electrochemical corrosion corrodes the metal faster than rust in air. Anodic protection The zinc plates help, but they don't completely save.
The insulation of the windings is critical for marine conditions, and if water reaches the stator, the motor will burn instantly, so regular leakproofness checks of the lower shaft seal are a must.
- 🌊 Wash the engine with fresh water immediately after returning from the sea.
- 🌊 Lubricate exposed metal parts with an anti-corrosion spray.
- 🌊 Keep the motor upright so that water does not get into the cooling system (if any) or to the omentums.
Typical breakdowns and ways to eliminate them
Judging by forums and service centers, the most common problem is the failure of the control board (controller), which often happens when you suddenly switch speeds from full forward to full back or when you work at the current load limit. Electronics He doesn't forgive overheating.
Second place is mechanical damage to the propeller and the shaft. Plastic screws break against objects hidden under the water. It's good that they break, saving the engine shaft, but the spare screw should always be with you. The replacement takes 5 minutes, but without the spare fishing is over.
The third problem is the oxidation of the contacts at the motor head foot connection, and vibration and water do their job, and regular lubrication of the contacts with a special lubricant for electrical connections prevents power loss and heating.
90% of breakdowns of electric motors are not related to factory defects, but to improper operation of the battery (deep discharge) or mechanical blows of the screw.
Frequently Asked Questions (FAQ)
Can I use a car battery for an electric motor?
Technically possible, but highly discouraged. Starter batteries are not designed to deliver low-power current for long periods of time. They will quickly lose capacity and may fail after 10 to 20 deep discharges. Only use traction batteries.
Which screw is better: 2-blade or 3-blade screw?
Two-blade propellers are usually more efficient at low speeds and create less noise, which is important for fishing. Three-blade propellers give a smoother run and work better at high speeds, but consume more energy. For PVC boats, 2-blade is more often optimal.
Do I need to remove the motor from the boat during transportation?
It is advisable to take pictures, especially if you often drive on the highway at high speeds. Vibration and oncoming air flow can shake the fastening mechanisms. If you can not remove, be sure to fix the hummulus and lift the lower unit as high as possible.
Is it true that the electric motor is weaker than the gasoline?
At top speeds -- yes, electric motors rarely deliver more than 10-12 km/h on a PVC boat. But on low-speed (trolling), they often outperform low-power gasoline analogues (2-3 hp), providing a more stable speed without jerks.
