Haswing Osapian 40 MAX Electric Motor
The Haswing Osapian 40 MAX is a versatile next-generation electric motor designed for anglers who value smooth boat handling, energy efficiency, and cutting-edge technology. Instead of a traditional gear switch, it features a Maximizer system that allows for smooth speed adjustment, significantly enhancing battery energy use efficiency.
Thanks to the Maximizer technology, runtime on a single charge can be extended up to five times compared to motors with classic controls. The Osapian 40 MAX is also perfect for trolling, where precise speed control is crucial.
The motor delivers 500W of power and 40 lbs of thrust, providing ample propulsion for boats up to 4 meters in length. The 5-LED battery level indicator lets you monitor voltage status, while the telescopic tiller with adjustable length (21–35 cm) and tilt angle (110°) offers great flexibility in use.
This model is equipped with a 2-blade propeller measuring 23 cm in diameter, capable of up to 1380 RPM, and features a skid plate to protect against bottom strikes. The shaft is made of anodized aluminum, making it corrosion-resistant and suitable for use in both freshwater and saltwater environments.
