The Momentum U2 5hp equivalent fills a crucial gap in the electric outboard market, sitting between standard 1kW motors and heavier 3 kW+ systems. It delivers a continuous power output of 2.5kW, more than twice that of popular 1kW integrated outboards, yet weighs less. Designed to replace 4- to 6-hp petrol engines, it delivers the torque you need for tenders, small fishing boats, and day sailors without the noise, fumes, or maintenance of a combustion engine.

Modular "Carry-Anywhere" System

What sets the Momentum U2 apart is its intelligent modular design. Instead of struggling with a single heavy unit, the system breaks down into three lightweight components for effortless transport:

Motor: 9kg (Short Shaft)
Battery: 8kg
Transom Bracket: 2kg

This means the heaviest item you ever lift is just 9kg, making it the easiest outboard in its class to mount and dismount from your transom.

Battery & Performance

The unit includes a quick-swap 1.4kWh lithium-ion battery that integrates seamlessly into the top of the motor. It provides an exceptional range for its size, capable of pushing a small boat at cruising speeds for hours. For those needing more power, the system can deliver up to 3kW of peak output when connected to external batteries.

Pro-Level Power Boost

While the integrated battery provides a robust 2.5kW, the Momentum U2 is engineered for flexibility. Uniquely, it can be connected to any standard 48V external battery bank (LiFePO4 or Lead Acid). Doing so not only extends your range indefinitely but also unlocks the motor's full potential, boosting output to a peak of 3kW. This extra power is often the difference needed to get small, lightweight tenders onto the plane, a feat standard 1kW motors simply cannot achieve.

User-Centric Features

Smart Display: A high-contrast colour screen built into the tiller shows real-time battery status and trip data, even in bright sunlight.
Folding Tiller: The multi-function tiller folds away for compact storage and features a safety lockout and reverse function.
Easy Trim: A single-lever action lets you adjust the trim to five positions (5° to 27.5°) or tilt it completely horizontal for shallow-water use or storage.

What’s Included

Momentum U2 Motor: Available in Short (39cm) or Long (52cm) shaft.
1.4kWh Lithium Battery: Quick-release design.
Transom Mount: Robust and quick-release.
Charger: Standard battery charger.
Accessories: Kill switch x2, prop tool, and instruction manual.

Durability and Safety

Built for the marine environment, the Momentum U2 features IP-rated waterproof connectors and a magnetic kill switch for safety. Its passive water cooling system keeps the motor running efficiently without the complexity of internal pumps, ensuring reliable, maintenance-free operation season after season.

Zero-Maintenance Cooling

The Momentum U2 utilises a 100% passive water cooling system. By eliminating the need for a mechanical water pump or rubber impeller, we have removed the most common maintenance headache associated with outboards. There are no intakes that can clog with debris and no impellers to replace, ensuring absolute reliability.
