Frequently asked questions

What does 40 lbs of thrust mean?

It describes the motor’s maximum static thrust rather than the permitted boat weight or engine horsepower. Forty pounds of thrust corresponds to approximately 18 kgf and is intended for moving smaller boats at moderate speeds.

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 required running time, selected speed and total boat load.

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

Running time depends on battery condition, boat weight, wind, waves and the selected speed. A fully charged 105 Ah battery may provide approximately two hours at maximum output, while lower speed settings allow longer operation. Sufficient reserve capacity should always be retained for the return journey.

Can the Osapian 40 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 corrosion protection.

Is the motor suitable for a 4.7 m boat?

The manufacturer gives a maximum recommended boat length of 4.7 m and a total load of 320 kg. Actual suitability depends on hull shape, wind resistance, current and intended use. A 55 lbs model may provide a more useful safety margin for heavier boats or windy conditions.

Can this motor make a boat plane?

Generally, no. The Osapian 40 is designed for moderate cruising, manoeuvring and trolling rather than high-speed or planing performance.

Does the motor have variable speed control?

No. This model has five fixed forward speeds and three fixed reverse speeds. A continuously variable model is more suitable when very precise trolling speed and improved energy efficiency are required.

When is the Haswing Osapian 40 lbs the right choice?

The Osapian 40 is suitable for owners of smaller boats who need a simple, quiet and easily transported electric motor. It works well for trolling, lake fishing and moderate cruising where a petrol engine is unnecessary or prohibited.

Choose a 30 lbs model for a particularly light boat and shorter journeys. The Osapian 55 lbs provides additional thrust reserve for heavier loads, larger boats and windy conditions. A GPS bow motor is more suitable when virtual anchoring, remote control and route functions are required.

Expert recommendation

Before choosing the motor, calculate the actual combined weight of the boat, battery, equipment and occupants. It is sensible to 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. Start the motor only when the propeller is sufficiently submerged and the surrounding area is clear.

Connect the battery with the speed selector in the neutral position and verify the polarity. Disconnect the battery before cleaning or removing the propeller. Do not fully discharge the battery, as reserve capacity is required for the return journey. Remove fishing line, weeds and other debris from the propeller after use. Rinse the submerged components with fresh water after saltwater operation and store the motor in a dry place. Maintain the battery according to its manufacturer’s storage and charging instructions.

Quiet propulsion for a smaller boat

The Haswing Osapian 40 lbs provides 40 lbs of thrust, straightforward tiller control and eight speed settings in a motor weighing approximately 7 kg. It is a practical 12 V propulsion option for anglers who want quiet and uncomplicated operation.
