Feature:1. The waterproof level reaches IP68, and it can be used underwater for a long time, effectively protecting the motor from seawater corrosion.2. The bearing is made of stainless steel, resistant to impact and corrosion, and effectively prolongs its service life.3. There is connecting ring at the upper and lower positions of the magnet, which can be used to lock the magnet and prevent the magnet from falling.4. The solder joints of the motor leads are potted inside the motor, which can meet the 200m suppression test.5. The motor kit has strong power, high torsion and highspeed operation, which is suitable for surfing boat underwater propulsion.Specification:Item Type: 65111 MotorMaterial: Japanese imported silicon steel sheet + stainless steel + copperModel: 65111Motor Size: Approx. 65 x 111mm / 2.6 x 4.4inPropeller Size: Approx. 1 x 4.4 x 18.4cm / 0.4 x 1.7 x 7.2inMaximum Power: 3kwContinuous Power: 1.5kwMotor Stator Slot: 12Shaft Diameter: Approx. 10mm / 0.4inNumber of Motor Poles: 6Motor KV Value: 130KVMotor Wire: 12AWG WireMaximum Voltage: 14SMaximum Current: 70ANo-Load Current: 2.2A 10VWaterproof Rating: IP68Weight: 1.4 kg / 3.1 lb(approx.)For surf boat underwater propellerUnderwater propellerFully waterproof motorRecommended for electric boat prototypes (airfoil, jet surfing, etc.)Comply with ROHS standard and CE and ROHS certification, including propellerThe Thrust Under The Conditions Of Reaching This Voltage And Current is as follows:48.5v 2.7A 5kg48.5v 8.2A 10kg48.5v 18.2A 15kg48.5v 20A 17kg48.5v 25A 19kg48.5v 30A 21kg48.5v 35A 23kg48.5v 40A 24kg48.5v 51A 27kgPropeller Fixing Method:1.
