The Torqeedo Ultralight 1103 AC is a lightweight electric outboard designed specifically for fishing kayaks, canoes and very light boats. It uses a direct-drive motor with 1,100 watts of input power, 540 watts of propulsive power and a built-in 915 Wh lithium-ion battery. Torqeedo rates it as the equivalent of a 3 HP gasoline outboard for shaft power.
The Ultralight 1103 AC combines electric propulsion with built-in GPS, an onboard computer, real-time range and runtime information, a kayak steering connection, manual trim and a mount designed for fishing-kayak applications. Its standard weedless propeller is designed for use around aquatic vegetation.
The Ultralight 1103 AC delivers 1,100 watts of input power and 540 watts of propulsive power. Torqeedo lists maximum overall efficiency at 49% and identifies the motor as a 3 HP equivalent based on shaft power.
The direct-drive design is intended to provide quiet electric propulsion without the exhaust and fuel handling associated with a gasoline outboard. Torqeedo describes the 1103 AC as an ultra-quiet direct-drive motor for kayak applications.
The Ultralight 1103 AC uses an integrated 915 Wh lithium-ion battery. The battery has a nominal voltage of 29.6 V and a final charging voltage of 33.6 V. Torqeedo lists the battery weight at 6.0 kg, while the complete motor system weighs 15.3 kg.
The integrated battery includes a GPS receiver, and the system’s onboard computer uses positioning information to calculate range and runtime. A compatible solar charging solution can also be used to charge the battery while operating, provided the appropriate accessories are installed.
Torqeedo’s published performance figures show that speed, range and runtime depend on the boat, load, propeller and operating conditions. In one published Ultralight 1103 AC example, the system reached approximately 5.8 km/h with a range of 53.3 km and 9 hours 11 minutes of runtime at low power; at full throttle the example showed approximately 12.5 km/h, 10.4 km range and 48 minutes of runtime. These figures are illustrative rather than guaranteed performance for every kayak or boat.
For this reason, the onboard computer’s real-time range calculation is particularly useful when conditions, load or operating power change during a trip.
The Ultralight 1103 AC has built-in GPS and an integrated onboard computer. The throttle display provides operating information such as battery status, remaining range, speed and input power, helping the operator monitor the electric drive while underway.
GPS-based range calculation is one of the key differences between a simple electric trolling motor and the Ultralight system. The available range estimate changes with operating conditions rather than relying only on a fixed battery-time calculation.
The Ultralight 1103 AC is designed around fishing-kayak use. The mounting system connects with compatible kayak steering, and the steering connection can be locked. Torqeedo also describes an angler mount with tilt and park functionality and mounting options developed for popular kayak brands.
The motor can be manually trimmed through four positions. The tilt system includes impact protection, allowing the drive unit to move upward when an underwater obstacle is encountered rather than transmitting the entire impact directly through the motor assembly.
The standard propeller for the Ultralight 1103 AC is the v10/p1100 weedless propeller. Torqeedo describes this propeller as a fishing-oriented design intended to reduce weeds wrapping around the propeller when operating in vegetation.
The published specification lists a maximum propeller speed of 1,450 rpm. The propeller specification is important when comparing the Ultralight 1103 AC with other electric outboards because thrust and efficiency depend on the complete motor, propeller and boat setup.
The Ultralight 1103 AC uses a throttle control with stepless forward and reverse drive. The system provides direct control over propulsion while the onboard computer displays operating information.
The emergency magnetic kill switch is designed to stop the motor quickly if the operator becomes separated from the control system. Torqeedo’s documentation describes the emergency magnetic kill switch as part of the Ultralight system.
The Ultralight 1103 AC is specified with an IP67 protection class. The published technical data describes protection against dirt and water ingress under the stated IP67 test conditions.
Electrical components should still be operated and maintained according to Torqeedo’s instructions. Waterproofing ratings do not eliminate the need for correct connectors, battery handling and routine inspection.

The published technical data lists the Ultralight 1103 AC shaft length at 51 cm (20.1 inches). The motor without the mounting system is approximately 76.0 x 26.0 x 32.3 cm according to the published technical data.
The complete system weighs 15.3 kg, including the 6.0 kg integrated battery. This relatively low system weight is one reason the Ultralight platform is aimed at kayaks and very light boats.
The Ultralight 1103 AC battery can be charged using the appropriate Torqeedo charger. Torqeedo also identifies a 90 W charger and a 50 W solar charger as available accessories for the Ultralight 403/1103 battery family.
Solar charging can allow the battery to be charged during operation when the appropriate solar accessory is connected. Charging time depends on the selected charger, battery state and charging conditions.
The Ultralight 1103 AC is designed primarily for fishing kayaks, canoes and very light boats. Torqeedo specifically positions the Ultralight range for kayaks, canoes and very light boats, with the 1103 AC providing the higher-power 3 HP-equivalent option in the range.
The motor can be particularly useful where low noise, low system weight, integrated GPS information and easy kayak installation are important. The correct application still depends on the boat’s weight, hull design, load, water conditions and local operating requirements.
Before installing an Ultralight 1103 AC, confirm that the mounting system is compatible with the kayak or light boat. Torqeedo’s documentation specifically warns that the 1103 AC uses stronger mounting components than the Ultralight 403 AC; the 403 mounting hardware should not simply be reused with the 1103 AC.
Installation should also account for steering integration, battery access, throttle position, emergency-stop operation and propeller clearance. Use the mounting hardware and procedures specified for the Ultralight 1103 AC rather than adapting components intended for a lower-power model.
If you are comparing the Ultralight 1103 AC with other electric outboard motors, consider battery capacity, total system weight, propulsive power, mounting requirements, shaft length, steering integration, range calculation and the type of boat you intend to power.

It uses an integrated 915 Wh lithium-ion battery with a nominal voltage of 29.6 V. The battery weighs 6.0 kg and is part of the 15.3 kg complete motor system.
Published performance examples show a maximum range of about 53.3 km at low power under specified test conditions. At full throttle, the same example shows about 10.4 km. Actual range varies with boat, load, propeller, speed and environmental conditions.
Yes. Torqeedo specifically positions the Ultralight range for fishing kayaks, canoes and very light boats, and the 1103 AC is the 3 HP-equivalent model in the range.
Yes. The system has built-in GPS and an onboard computer that uses GPS information for range and runtime calculations.
No. Torqeedo’s documentation explains that the 1103 AC uses stronger and different mounting components because it is heavier and more powerful. The 403 mounting hardware should not be used for the 1103 AC.
