Perfect for daysailers up to 1,650 pounds, tenders, dinghies and duck boats, this motor sets a new standard for quiet, lightweight and ecologically-friendly propulsion. With a built-in ultra-efficient, lithium-manganese battery pack, Torqeedo Travel outboards deliver power and range. (Range varies depending on speed, conditions and boat type. At full throttle, run time is 42 minutes; slower speeds result in up to six hours or more!) The Travel 503 is completely waterproof, clean and easy to use with push-button starting and a four-function display that shows percentage of battery power remaining, speed over ground and remaining range. Speed and range are calculated using an integrated GPS receiver. An audible signal warns you when the battery charge drops to 30%. The smallest carbon footprint of any propulsion motor.Owner's Manual Key Features Environmentally friendly - no matter how or where you store your Travel – theres no risk of leakage or fuel smells Quiet and lightweight Completely waterproof High-performance lithium battery integrated into the outboard: high energy density, excellent high-current capacity, safe Charging socket and USB port for charging with onshore power 12V Also solar chargeable including while on voyage Can also be used as a power source for smartphones, lamps etc. via a USB adapter On-board computer with GPS-based calculation of remaining range Audible alarm issued when battery charge is low Magnetic kill switch stops the motor in emergencies without impairing its waterproof qualities Can be easily dismantled for transport and space-saving storage Two year manufacturer warranty Specifications Input Power: 500W Voltage: 29.6V Output Power Watts: 220W (1.5hp equiv. propulsive power, 2hp equiv. thrust) Shaft Length: 24 7/8” Remote Control: No (can add remote throttle) Battery Type: Internal Waterproof (IP67)
