KRONOS: the 5 advantages of the electric outboard motor by Weenav

Choosing an electric motorisation for a boat is betting on quieter, cleaner, and more economical navigation in the long term. However, not all solutions are equal when it comes to taking action: installation complexity, reliability, power autonomy, control... At Weenav, we have designed the KRONOS, our 100% electric outboard motor, to concretely address these challenges. Here are the 5 advantages that distinguish the KRONOS from other electric propulsion solutions on the market.

1. A complete integration designed for quick assembly

This is one of the key strengths that most clearly differentiates the KRONOS from competing solutions. With many electric motorisations for boats currently available, installation requires connecting and securing up to 8 separate modules: controllers, converters, cooling, dedicated wiring... A real headache for shipyards and installers, resulting in extended assembly times and frequent site visits to correct adjustments.

With the KRONOS, we have made the opposite choice: a unique engine block, developed entirely by our engineers, from the transmission to the drive head. All essential components for the electric propulsion system are integrated directly into the engine. In practical terms, only the batteries need to be installed separately. The result: simplified installation, considerable time savings for installers, and preserved onboard space. This is a decisive competitive advantage for any professional who needs to equip or retrofit a fleet within controlled deadlines.

2. A scheduled engine overhaul at 5,000 hours

The electric motorisation is known for its low maintenance needs, and the KRONOS takes this logic even further. Thanks to a base specifically designed for electric propulsion, as well as a simplified architecture with a significantly lower number of moving parts than a thermal engine, the KRONOS reduces maintenance operations. A complete overhaul is therefore only necessary after 5,000 hours of operation.

For intensive professional use such as electric boat rentals, river shuttles, fishing or tourist water activities, this interval represents a significant reduction in operating costs and capital expenditures. Fewer technical stops, fewer wear parts to replace, and a electric propulsion designed to last over time, in line with Weenav's commitment to more sustainable and profitable navigation.

3. A continuous power that truly delivers on its promises

On the electric propulsion market, an engine rated at 300 horsepower does not always deliver 300 horsepower in real use. Some solutions display a nominal power that only corresponds to a short-duration peak. As soon as the engine heats up or the navigation extends, the power electronics automatically reduce the speed to protect the system. The boat then loses performance at the moment it is most needed.

The KRONOS does not operate this way. When we announce continuous power, it is the power that the engine is actually capable of delivering continuously, without thermal limitation or degradation over time. A KRONOS 300 running at full load for an entire afternoon continues to deliver its 300 horsepower from the first to the last pass. This is a major differentiating factor for boating professionals, whose activities such as rental, fishing, shuttles, or fleet operation rely precisely on the consistency and reliability of the available power, trip after trip.

Each variant of the KRONOS range thus announces a truly usable continuous power, from the most accessible to the most powerful:

4. A peak power designed for demanding situations

In addition to its continuous power, the KRONOS also has a peak power, available on demand for phases that require an immediate increase in energy: de-watering, rapid acceleration, overtaking, or navigating in more demanding conditions. The electric torque, available instantly, allows for an immediate response to commands and optimal manoeuvrability, even in the most precise manoeuvres.

For professionals, this on-demand capability has a real operational value. A river shuttle or fishing boat operator rarely carries a constant load: passengers, equipment, cargo add weight to the vessel from one outing to the next. With the KRONOS, this variability is no longer a problem: the engine can always mobilise the necessary power to compensate for a heavier load, maintain a course in degraded conditions, or react without delay in case of unforeseen events. It is an adaptability that reassures as much as it secures daily operations, without ever questioning the reliability of the engine's continuous power, which remains guaranteed at all times.

Each KRONOS model thus has a clearly defined peak power:

Across the entire range, this peak power represents an additional power of 39 to 63% that can be mobilised temporarily.

5. A Garmin instrumentation for intuitive and complete control

The KRONOS is equipped with a Garmin instrumentation,integrated into our energy management system. This touchscreen interface allows real-time monitoring of the engine activity and control of the entire electric propulsion system directly from the helm.

Thanks to Garmin EmpirBus, all the parameters of the boat are centralised on an ergonomic programmable controller: charge monitoring, engine status, alerts, remote security updates. A boating experience designed to reassure both leisure boaters and professionals who operate their boats on a daily basis.

The KRONOS, an electric propulsion system designed to go further.

Complete integration for a quick installation., Maintenance intervals at 5,000 hours, reliable continuous power,, peak power,, Garmin instrumentation.for precise steering: these 5 advantages make the KRONOS an electric propulsion solution designed to meet the real-world requirements of the field, whether it is a new boat project or an electric retrofit.
