HASWING OSAPIAN 55 LBS ELECTRIC MOTOR

The Haswing Osapian 55 lbs is a 12 V electric outboard motor for inflatable boats, fishing boats and other small craft equipped with a suitable transom. Its 55 lbs of thrust provides a greater reserve than the 40 lbs model when carrying heavier loads or operating in wind and waves. It is intended for moderate cruising, trolling and travelling between fishing areas.

Suitable for use

• Inflatable and fishing boats

• Canoes and kayaks with a suitable transom mount

• Trolling and quiet fishing

Frequently asked questions

What does 55 lbs of thrust mean?

It describes the motor’s maximum static thrust rather than the permitted boat weight or engine horsepower. Fifty-five pounds corresponds to approximately 25 kgf of thrust and provides additional reserve for heavier loads and more demanding conditions.

Is a battery included?

No. A separate 12 V deep-cycle battery is required. The manufacturer recommends a capacity of approximately 105 Ah, although the appropriate capacity depends on the desired running time, selected speed and total boat load.

How long will the motor run on a 105 Ah battery?

Dividing 105 Ah by the maximum 55 A draw gives an ideal result of slightly less than two hours at full power. Actual running time is normally shorter because of usable battery capacity, temperature, age and load. Lower speed settings permit longer operation, but sufficient reserve should always be retained for the return journey.

Can the Osapian 55 be used in salt water?

Yes. It is suitable for both fresh and salt water. After saltwater use, rinse the submerged components with fresh water, dry the electrical connections and inspect the propeller and sacrificial anode.

Is the motor suitable for a 5.5 m boat?

The manufacturer gives a maximum recommended boat length of 5.5 m and a total load of 400 kg. Actual suitability depends on hull shape, wind resistance, current and intended use. These figures should be treated as guidance rather than guaranteed performance limits.

How does the Osapian 55 differ from the Osapian 40?

The Osapian 55 provides 15 lbs more thrust and uses a three-blade propeller. It is better suited to heavier boats and loads but draws up to 55 A at full power and weighs approximately 1.2 kg more. The Osapian 40 is a lighter and less power-hungry choice for a smaller boat.

Does the motor have continuously variable speed control?

No. This model has five fixed forward speeds and three fixed reverse speeds. A continuously variable motor is preferable when very precise trolling speed and more efficient battery use are required.

Does the Osapian 55 have GPS or a virtual-anchor function?

No. The Osapian 55 is a manually controlled transom motor. A GPS-equipped bow motor is required for virtual anchoring, remote control and automated route functions.

When is the Haswing Osapian 55 lbs the right choice?

The Osapian 55 is suitable for users who need a 12 V electric motor for a heavier inflatable or fishing boat. Its additional thrust is useful when several people or a larger amount of equipment are carried, or when the boat is used on more exposed water where wind has a greater effect.

The Osapian 40 is more appropriate for a smaller and lighter boat because it weighs less and draws less current at full power. Anglers who require GPS anchoring, remote operation and automatic routes should consider a GPS-equipped bow motor.

Expert recommendation

Before selecting the motor, calculate the actual combined weight of the boat, battery, occupants and equipment. Retain a thrust reserve because headwinds, waves and current increase power consumption. Use a deep-cycle battery, a compatible charger, and cables and electrical protection sized according to the motor manual. Attach the motor evenly to the transom and check the clamp screws before every trip.

Connect the battery with the speed selector in neutral and verify the polarity. Start the motor only when the propeller is sufficiently submerged and the surrounding area is clear. Disconnect the battery before cleaning or removing the propeller. Remove fishing line and weeds from the propeller after use. Rinse the submerged components with fresh water after saltwater operation. Do not plan a journey using only the LED battery indicator, as it provides an approximate voltage-based reading rather than an exact remaining runtime.

Additional thrust for a heavier boat

The Haswing Osapian 55 lbs provides 55 lbs of thrust, straightforward tiller control and eight speed settings in a motor weighing approximately 8.2 kg. It is a practical 12 V propulsion option for anglers who need quiet operation on a small or medium-sized boat.
