Choosing an auxiliary engine for a boat is often a deciding factor in comfortable fishing, especially when it comes to trolling or maneuvering in ICE-free zones. Haswing Osapian 55 It has proven to be a robust middle-class solution that combines sufficient power and sophisticated ergonomics, and it attracts attention not only with its declared traction, but also with the presence of a trolley, which makes transportation of equipment much easier.
In modern fishing, where silence and environmental standards are required, electric traction comes to the fore. Electric motors This allows you to sneak up on fish without the splashes and vibrations that frighten aquatic life, and in this article we will discuss in detail the technical details, real performance indicators and features of service of this particular model, so that you can make an informed decision about buying.
It is worth noting that the market is saturated with offers, but Haswing It is a sustainable niche because of its value-for-money balance, and many anglers are looking for alternatives to expensive brands, and the Osapian 55 lbs is often the gold standard in the budget segment, and understanding the real-world capabilities of the engine will help avoid frustration and pick up the right equipment.
Technical specifications and design
The motor is structurally made of composite materials and stainless steel, which provides resistance to corrosion in salt water. The weight of the unit is about 13.5 kg, which is the average for devices with such thrust. stanza It is made of stainless steel and has a telescopic elongation, which allows you to adjust the depth of the screw immersion depending on the load of the boat.
Control is performed by a rotary handle, which can be mounted on both the left and starboard sides. Rotating the handle 360 degrees allows smooth adjustment of speed from minimum to maximum. handleThis displays the voltage level in real time.
⚠️ Warning: Do not leave the motor submerged in water for a long time unnecessarily, as this can lead to the rotor fouling with algae and accelerated corrosion of metal elements, even if they are coated with anticory.
The key feature of the model is the presence of quick-cart This is rare in the low-end segment, where you most often have to buy transport wheels separately, and the cart is securely fixed on the lower unit and allows you to easily move the engine along the shore or store it in an upright position without taking up much space.
Performance and Real traction
The manufacturer's stated thrust of 55 pounds (approximately 25 kg) is quite a serious figure for boats up to 4.5 meters long with a full load. speed It will depend on a variety of factors: the shape of the hull, the condition of the bottom, the strength of the wind and current. On calm water, a PVC boat with a single fisherman reaches a speed of about 5-6 km / h.
It's important to consider that maximum thrust is achieved at maximum speed, which quickly puts the battery down. To effectively troll, you usually use 20-30% of the power, and in this mode the motor operates almost silently and provides stable wiring of the bait. Vint has three blades and is made of durable plastic, which when hit by a hard obstacle bends, but does not break the gearbox.
For clarity, compare the declared and expected parameters of work in different conditions:
| Parameter | Meaning | Note |
|---|---|---|
| Maximum traction | 55 lbs (25 kg) | With a fully charged battery |
| Current intake (max) | 52 A | Full power. |
| The length of lower unit | 91 cm | With the possibility of elongation |
| Motor weight | 13.5 kg | No battery. |
As can be seen from the table, the current consumption at the maximum is quite high, so the use of a battery of smaller capacity than recommended will lead to a sharp decrease in operating time. The best choice It will be a traction battery with a capacity of 100 Ah.
The real speed of the boat with the engine Haswing Osapian 55 lbs on calm water is 5-7 km / h, which is ideal for trolling and moving between fishing points.
Control system and ergonomics
The ergonomics of the control handle are well-designed for devices in this price range: the grip is comfortable, the rubber pads do not slide even with wet hands; the speed switch is smooth, without jerking, which is important when catching fish or wiring a wobbler at the very water slice. The tilt angle fixing mechanism allows you to quickly raise lower unit when passing through shallow water.
There's a built-in voltmeter on the handle, and although it shows the total voltage, not the percentage of residual capacity (which requires more sophisticated BMS systems), it's enough to monitor the condition. batteryA voltage drop under load is a sure signal to end fishing or switch to economy mode.
The power cable is equipped with reinforced terminals that are securely fixed to the battery. The length of the cable allows you to place the battery in the nose or in the center of the boat, which contributes to the proper weighting. However, when PVC is installed in the nose of the boat, additional attachment may be required, since there is no standard transom arm for the nose.
To prolong the life of the terminals and contacts, lubricate them with a special silicone lubricant before each fishing trip to prevent oxidation from salt water or moisture.
Power and battery selection
The motor runs on 12 volts. This is the standard for most electric motors up to 80 lbs. The main mistake for beginners is to use car starter batteries. They are designed for short-term high-current returns to start the engine, not for long-term operation under load. Haswing Osapian It is a traction battery (Deep Cycle) that is required.
The operating time depends on the battery capacity and operating mode. If you plan to actively use the maximum speed to overcome long distances against the wind, stock up on a battery with a capacity of 100-120 Ah. For quiet fishing in windless weather at medium speeds, 75 Ah will suffice.
- 🔋 Lead acid (AGM/GEL): Reliable, inexpensive, but heavy and afraid of a deep discharge below 50%.
- ⚡ Lithium-iron-phosphate (LiFePO4): Light, keep the voltage to full discharge, serve 5-10 times longer, but are more expensive.
- 🌊 GEL: Good compromise, no maintenance, safe but sensitive to overcharging.
Use of lithium batteries with BMS The Battery Management System has the huge advantage of having a steady motor speed right up to full discharge, and the lead batteries will give off less current as they discharge, and the boat speed will drop.
Can I use a car battery?
The starter car battery is only available in emergency cases, and in deep discharge, it sulfates quickly and fails, losing up to 50% of its capacity after several such cycles.
Installation and preparation
The process of installing the motor on the transom does not require special tools. Thanks to the fast fast fastening system, it takes a couple of minutes. It is important to make sure that the transom of the boat will withstand the weight of the engine and dynamic loads. For inflatable boats, it is recommended to use a transmutation board or a reinforced transmolant.
Before the first start, check the tightening of all screw joints and lubricate the moving parts. Pay special attention to the position of the screw: it must be immersed in water at least 25-30 cm below the surface to avoid cavitation and air capture, which reduces efficiency and can damage the blades.
☑️ Check before the first launch
When used in salt water, fresh water washing is mandatory after each exit, the salt crystallizes in mobile compounds and can "coke" the turning mechanism or damage the osteoils, and it is also recommended to periodically lubricate the screw shaft with water resistant lubrication.
Comparison with competitors and analogues
There are many analogues on the market, such as Minn Kota, Watersnake or Chinese brands like Flox. Haswing Osapian It will be more expensive than many of them in terms of configuration (the presence of a cart) and build quality for its price. Minn Kota will be more reliable and durable, but will cost 2-3 times more expensive with similar traction specifications.
Chinese know-naimes often fall short of hand-holding and weak rotor plastics. Haswing is a European-standard quality control, but if you want a motor with GPS anchor or remote control, you’ll have to look at more expensive models or buy some accessories.
In the up to $300-400 segment, the Osapian 55 lbs remains one of the leaders in price/quality/function ratios, ideal for those who want to switch from sedans to electric traction without overpaying for the brand.
