Choosing an auxiliary engine for an inflatable vessel often becomes a turning point in the development of water motor skills. boat-engine 55 The gold standard for most PVC boat owners, which is 3 to 4 meters long, allows them to move confidently against the wind and current without creating excessive noise that scares the fish.
Unlike gasoline analogues, electric units do not require complex preparation for the season, oil or fuel change. Traction 55 lbs (about 25 kg) is the optimal balance between weight, size and performance. Many beginners mistakenly believe that the more powerful the motor, the better, but for light boats, excess force can lead to instability on the water and a quick discharge of the battery.
In this article, we will discuss in detail all the nuances of the operation of such devices, you will learn how to choose the right battery, install a data-devil on a transom and maintain the mechanism so that it will last for many years. The efficiency of the electric motor directly depends on the state of battery charge: at a discharge below 50%, the thrust can fall by 30-40%.
Technical specifications and capabilities of the motor
The main parameter that the buyer looks at is the thrust force, measured in pounds (lbs). The number 55 means that the engine is able to develop a force equivalent to 55 pounds. To translate into more understandable metric units, it is worth remembering that 1 lb is approximately equal to 0.45 kg, but this is not the maximum speed, namely the traction force. Current consumption These models typically have 40 to 55 amps at top speed, which requires a capacious battery.
Most models are designed with a telescopic diewheel that allows the propeller to be immersed to the desired depth, which is critical to prevent cavitation and capture of the bottom algae, and the depth adjustment is done by simply turning the grip or pressing the lock, depending on the brand.
The control system is most often implemented through a tube with a telescopic handle. Rotating the tube changes direction, turning the handle regulates speed. Modern models can be equipped with electronic speed control, which allows smoother travel and saves charge.
⚠️ Warning: Never run an electric motor out of water or without the propeller diving. Although they are cooled by off-shore water, working dry can damage the glands and cause the anchor windings to overheat in minutes.
It's important to consider the weight of the device itself. 55-pound models typically weigh between 9 and 12 kg. This is already a tangible load for a single inflatable boat that you have to carry manually. So you should pay attention to the materials of the case when choosing: composite alloys are lighter, but more expensive than aluminum.
Criteria of choice: what to pay attention to
The market offers many brands, and it's very easy to get confused about the specifications. power-driven outboard motor 55 You need to look not only at the price, but also at the design features that affect durability.
The first thing to determine is the type of attachment. For PVC boats, the ideal solution is a high-powered sling mount, which should have rubber linings to avoid damaging the cylinders or the slingboard, and some models have universal mounts that allow you to mount the motor on the bow of the boat, which is convenient for trolling.
The second important aspect is the speed switching system: mechanical switches are more reliable in moisture conditions, but can oxidize; electronic regulators provide smooth acceleration, but are more sensitive to voltage surges; for fishing, where noiselessness and accuracy are important, electronics are preferable.
- 🔋 Compatibility with batteries: Make sure that the engine terminals fit the standard battery terminals (usually these are bolt connections under the M6 or M8) nut.
- 🌊 Water protection: Look for the IP67 or IP68 markings, and the motor must withstand short-term full immersion, as the waves can cover the deadwill.
- ⚙️ The material from Daydville: Stainless steel is stronger but heavier. Aluminum alloys with anodization are lighter, but require careful handling when hitting stones.
Also worth paying attention to the presence of a battery charge indicator: the built-in LED or hand indicator on the tiller allows you to monitor the rest of the energy in real time, which saves from unpleasant situations far from the shore.
Comparison of popular models of electric motors
To make it easier, let's compare some of the popular models that are common on the market, all of which are about 55 pounds in thrust class, but they have their own specifications.
| Model | Traction (lbs) | Weight (kg) | Speed steps | Features |
|---|---|---|---|---|
| Haswing Cayman B 55 | 55 | 10.5 | 5 forward / 3 back / 3 back | Telescopic rample, LED indicator |
| Watersnake T24 | 54 | 7.8 | 5 forward / 3 back / 3 back | Superlight, composite deadville |
| Flox 55L | 55 | 9.2 | Stepless | Electronic governance, quiet move |
| Min Kota Endura 55 | 55 | 11.3 | 5 forward / 2 back / back | Classic, high reliability, heavy |
As you can see from the table, the weight variance can be substantial. Watersnake It's also a great advantage because it's made of composite materials, which makes it ideal for single boats. Min Kota It is a reliable standard despite its weight.
When choosing between mechanical and electronic speed control, you need to consider operating conditions. If you walk on overgrown bodies of water, the mechanics are easier to clean from coiled algae. For clean water and sports fishing, electronics will give you more comfort.
The secret to the durability of the screw
Plastic or composite screws, when hit by a rock, will simply break or crumple, retaining the motor shaft. The metal screw will pass the entire impact to the gearbox, which can lead to costly repairs. So for shallow water, a plastic screw is a plus, not a minus.
Selection of battery
The heart of any electrical installation is a battery. For a 55 lbs motor, the standard choice is a 12-volt battery. However, the key is capacity measured in ampere hours (Ah).
The optimal capacity for such a motor is considered to be a range from 100 to 120 Ah. The use of starter car batteries is not recommended, since they are not designed for long-term return of low-power current and quickly fail at deep discharge. traction Deep Cycle, which can discharge up to 20-30% without harming the plates.
The current alternative to lead-acid batteries is lithium-iron-phosphate (LiFePO4) batteries, which are 3-4 times lighter than lead batteries, have a greater lifetime of charge-discharge cycles and are not afraid of deep discharge, the only drawback is the high initial cost, but in terms of life they are often more profitable.
- 🔌 Charger: Be sure to use smart chargers with automatic shutdown. Boiling water overcharging is detrimental to any battery.
- ❄️ Temperature: Lithium batteries can't be charged in the cold. Lead batteries are more tolerant, but their capacity in the cold also drops.
- 🔗 Switching: Use wires with a cross section of at least 10 mm2 (copper). Thin wires will warm and cause a drop in voltage on the motor.
⚠️ Warning: When installing the battery in the PVC boat, be sure to use a sealed plastic box. The acid or electrolyte that hit the cylinder can instantly burn through the material, which will lead to flooding.
The calculation of the stroke time is simple: if the motor consumes 50 Amps, and the battery has a capacity of 100 Ah, then at a maximum speed (55-60 A), it will sit in about 1.5-1.7 hours. At average speeds (20-25 A), the reserve will last for 3-4 hours of active fishing.
Installation and installation instructions
The correct installation of the engine is the key to safe and comfortable operation. The process of mounting on the transom of the PVC boat does not require special tools, but requires attention to detail.
First, you need to fix the transom board (if it is not built in), it must be installed strictly vertically or with a minimum angle of inclination inside the boat, the motor is attached to the upper edge of the transmolor, the motor clips must cover the board tightly, excluding backlashes, but without excessive compression, which can damage wood or plastic.
Adjusting the depth of the dive is a critical step. The propeller must be below the bottom of the boat by at least 15-20 cm. If you lift the engine higher, air suction and cavitation will begin, which will reduce efficiency. If you lower it too low, water resistance will increase.
☑️ Pre-launch checks
Don't forget the safety cable. It's a safety feature, and the cable is attached to the handle of the motor at one end and the bolt on the transom or inside the boat at the other end, and if the motor's attachments are loosened and it falls into the water, the cable will prevent it from drowning or getting lost.
Lubricate rubber clip seals with silicone lubrication before each installation, which will prevent rubber from drying out and cracking, and make it easier to install in cold weather.
Maintenance and care of the electric motor
Electric motors require minimal maintenance, but they cannot be ignored. The main enemy of the mechanism is salt (if you walk on the sea) and sand. After every fishing, the deadwheel and the screw must be rinsed with fresh water.
Once a season, it is recommended to remove the screw and clean the shaft from the coiled hairs of the line or algae. They can damage the oal, which will lead to water entering the deadville and corrosion of the gearbox. Use special sprays to grease the mobile joints, displacing moisture.
The motor should be kept upright, in a dry room, in the winter at room temperature, and extreme temperature changes can cause condensation inside the electronic control units.
- 🔧 Replacement of brushes: In collector motors (most budget models), graphite brushes may need to be replaced after 300-500 hours, a simple procedure available to a home craftsman.
- 🧼 Contact cleanup: Check the battery connection terminals regularly. Oxidation of the contacts leads to heating and loss of power.
- 🛢️ Lubrication of the gearbox: There is oil in the lower gearbox, and it is recommended to change it every 2-3 years, checking for the presence of an emulsion (a sign of water intake).
Compliance with these simple rules will allow you to boat-powered electric motor 55 Electric propulsion is the future of small-scale water mechanization, combining sustainability, silence and reliability.
The main secret of long-term engine service is the purity of the screw and shaft, as well as timely recharging of the battery after each fishing, without waiting for a deep discharge.
Frequently Asked Questions (FAQ)
Which battery is better to choose for the 55 lbs engine: AGM or gel?
Both types are lead-acid and suitable for electric motors. AGM batteries are cheaper, better tolerate larger discharge currents (shock traction), but have a lower cycle life. gel (GEL) is more expensive, lasts longer at deep discharge, but are afraid of recharging and require a better charger. For a beginner, AGM will be a more budget-friendly and versatile option.
Can a 55 lbs electric motor be used as the main engine for a 3.6 meter boat?
Yes, for a boat with a length of 3.6 meters with one angler and light thrust equipment, 55 lbs (about 25 kg) will be enough for driving at a speed of 5-7 km / h. However, with a strong headwind or full load (2-3 people + cargo), the speed will drop, and the operating time will be reduced.
Why does the engine run in throttles or slow down?
The most likely cause is battery discharge. When the voltage drops below a certain threshold, the electronics start to turn off the motor for protection. The second is oxidation of the contacts or poor connection of the terminals. It's also worth checking if the algae that block the rotation are wound on the shaft.
Do I need to register a boat with an electric motor in GIMS?
According to the legislation of the Russian Federation (at the time of writing), small vessels with an engine of more than 8 kW (about 10.8 hp) are subject to registration. 55 lbs electric motor has a power of about 0.7-0.8 kW (1 hp), which is much less than the registration threshold. However, the rules can change, and the final decision is always with the GIMS inspector, so it is recommended to have the engine documents indicating the power.
