Choosing a traction motor for a PVC boat or a small boat always involves finding a balance between price, power and functionality. Haswing Osapian 30 It stands out as one of the most balanced solutions for the quiet fishing enthusiasts, and it attracts attention not only for its affordable cost, but also for its integrated sonar, making it a versatile tool for the fisherman.
In this material, we will analyze in detail the technical features of the device, methods of its installation and the nuances of operation in real conditions. Electric motor This series is positioned as a reliable assistant for maneuvering in the coastal zone and fishing in overgrown areas of the reservoir, where the use of a gasoline engine is impossible or impractical.
It is worth noting that the popularity of the brand Haswing It is growing thanks to the introduction of technologies previously available only in the premium segment. A unique feature of this model is the integration of the sonar sensor directly into the lower unit motor, which eliminates the need to buy and fasten a separate device. This greatly simplifies the preparation of the boat to the water.
Technical specifications and design features
Model Osapian 30 It is equipped with an electric motor with a declared thrust of 30 pounds (about 13.6 kg), which is the optimal indicator for inflatable boats up to 3.5-4 meters long with a full load. The design is made using composite materials that are resistant to corrosion and mechanical damage. lower unit has an adjustable angle of inclination, allowing you to adapt the engine to various conditions of depth and bottom relief.
The speed control system is implemented through a telescopic turn-based tube, with 5 forward speeds and 3 reverse speeds available, which allows the angler to precisely adjust the operating mode depending on the strength of the wind and current. Maximum speed The boat’s movement will depend on the weight of the vessel, but is usually around 5-6 km/h, which is enough for trolling or a silent approach to the fishing point.
The cooling system deserves special attention. The engine has water cooling, which ensures its efficient operation even under long loads. However, it is important to monitor the level of dip in the lower unit to avoid overheating. The engine screw is made of durable plastic, which bends when hit by an obstacle, but maintains its performance, although it may need to be replaced.
The overall dimensions and weight of the device allow one person to easily transport it in the trunk of the car. Mounting to the transom is carried out using powerful clamps that reliably lock the engine even when active on the wave. Telescopic barbell The bumple can be extended, providing comfortable control standing or sitting on a high seat.
Integrated sonar and navigation functions
One of the main "chips" of the model Haswing Osapian 30 It's a built-in sonar, and it displays depth, water temperature and bottom structure on a small LCD display on the handle of the tube, and it eliminates the need to drill holes in the hull of the boat to install a separate sonar sensor.
The screen is informative enough to distinguish between depth differences and the presence of fish, although its resolution is inferior to full-fledged cartplotters. For fishing in the daytime, the display is quite bright. At night, the backlight is turned on, which does not blind the eyes and allows you to control parameters without being distracted from the fishing process.
Accuracy of sonar readings
The depth readings have a minimal error, but it is worth considering that the sensor is attached to the engine. When the boat is moving or there is a heavy chop, small fluctuations in the numbers on the screen due to a change in the angle of immersion of the sensor.
In addition to depth, the device shows the battery charge, which is critical for route planning. Charge control It helps to avoid the unpleasant situation when there is not enough energy to return to shore, and the sonar function can be adjusted by selecting units of measurement (meters or feet) and sensor sensitivity.
Installation and installation on the boat
Installation process Haswing Osapian 30 The motor is mounted on the boat's trawler with screw clips. It is important to make sure that the thickness of the transom is within the permissible range specified in the instructions. It is recommended to put rubber gaskets before the puff so as not to damage the side of the inflatable boat or the PVC bag of the hard transone.
After the motor is physically fixed, it must be connected to the battery, and this uses terminal connections that come with the kit. Polarity of connection It's very specific: red wire to plus, black wire to minus. An error in connection can cause the electronics to fail, so be careful.
☑️ Checklist before first launch
Adjustment of the depth of diving of the lower unit is carried out by changing the angle of inclination of the motor relative to the transom. The optimal position is considered when the screw is below the water line by 15-20 cm, but does not create undue resistance. Proper installation guarantees maximum efficiency and no cavitation.
Operation and speed management
The motor is controlled by turning the handle of the handle of the handle, and to turn the device on, you need to press and hold the power button, then select the desired speed of rotation of the screw, the switching of speeds is smooth, without jerks, which is especially important when catching a predator on delicate baits.
Reversing mode makes it easy to maneuver in narrow spaces or push back from the shore. back-up It's designed primarily for maneuvering, not for long-duration, high-speed driving, and it can use up the battery faster if you're working in reverse mode.
The telescopic handle allows you to change the length of the bumper, when it is unfolded, the control becomes more comfortable for standing, and when it is folded, the motor takes up less space during transportation, and the length fixing mechanism is reliable and has no backlashes even after prolonged use.
Nutrition and autonomy of work
For work. Haswing Osapian 30 The manufacturer recommends using deep discharge batteries (Deep Cycle), which can give energy to a stable current for a long time. Car starter batteries can also be used, but their life is significantly reduced during this mode of operation.
The engine life directly depends on the battery capacity and the chosen speed of rotation of the screw. At the minimum speed, the engine consumes about 10-12 Amps, which allows you to spend 6-8 hours on water with a battery of 100 AH. At maximum traction, consumption increases to 30 Amps or more, reducing the autonomy time to 2-3 hours.
| Speed. | Current consumption (A) | Working time with AKB 100 Ah (h) | Recommended use |
|---|---|---|---|
| 1 (Minimum) | 10-12 | 8-9 | Trolling, waiting. |
| 3 (Mediocre) | 18-20 | 4-5 | Moving between points |
| 5 (Maximum) | 28-30 | 2.5-3 | Against the wind, the current |
To recharge the battery at home, you need to use a special charger that corresponds to the type of your battery. Control of the charge level It is better to carry out using a multimeter or built-in indicator on the motor, avoiding a deep discharge below 10.5 Volts, which is harmful for lead-acid batteries.
Maintenance and care of the electric motor
Like any machine, Haswing Osapian 30 After each release, especially if the fishing was in salt water, the motor must be thoroughly washed with fresh water, which will prevent corrosion of metal elements and oxidation of contacts.
Periodically, the screw and lower unit should be checked for winding fishing line or algae. Foreign objects can put additional stress on the engine shaft, causing it to overheat, and it is also recommended to lubricate the movable joints and the tilt mechanism with a special lubricant resistant to washing with water.
⚠️ Warning: Never run the engine out of water ("dry"). The lack of water cooling will cause instantaneous overheating and melting of plastic parts of the lower unit, which will entail costly repairs.
Store the electric motor in a dry room, in a vertical position to avoid deformation of the ramp. Before long winter storage, it is better to preserve the contacts of the battery, and clean the engine from dirt and lubricate with protective compounds.
Regular washing with fresh water and lubrication of moving parts are key factors that increase the life of the electric motor by 1.5-2 times.
