# The Smart Electric Outboard Motor: Zero Emission, Low Noise, and up to 85% Lower Running Costs
Meta description (paste into SEO settings): Meet SeaEdison's smart electric outboard motors — from the entry 1.2kW model to a complete intelligent propulsion solution for boats up to 16 meters, with autonomous cruising, electronic anchoring, and dramatically lower operating costs.
Across lakes, coastlines, and aquaculture farms, a quiet change is underway. The familiar roar and diesel smell of the outboard motor is giving way to something cleaner: a 100% electric, digitally connected propulsion system that thinks for itself.
At SeaEdison, we've spent eight years building exactly that. What began as a compact 1.2kW electric outboard motor has grown into a complete smart electric propulsion solution for leisure boats, fishing vessels, aquaculture workboats, and tender boats up to 16 meters.
It Starts With 1.2kW
The 1.2kW Electric Outboard Motor (model SE8-012) is our entry-level unit — and the ideal on-ramp to electric boating. Priced at just $599, it delivers strong, reliable electric drive for leisure, aquaculture, and tender boats, built around three simple promises:
- Strong power — 1.2kW of smooth, efficient thrust for everyday boating and water-sports.
- Quiet operation — a near-silent ride that keeps the peace on lakes and in wildlife-rich waters.
- Easy installation — a hassle-free, standard-mount design you can fit quickly.
It's 100% electric — no fuel, no oil changes, no fumes. Plug in the battery, connect the control line, and you're ready to go. But the 1.2kW unit is just the beginning of the story.
A Complete Smart Powertrain — Not Just a Motor
The 1.2kW model sits at the entry of our SE8 series, a scalable family of smart electric outboard motors that ranges from a single lightweight unit to a dual-motor system for larger working boats. Every model is a brushless DC motor engineered in-house for efficiency, longevity, and quiet power.

The 1.2kW series runs on a 51.2V platform (24–51.2V), while the larger 4–12kW models use a 153.6V system (72–180V). Matching lithium iron phosphate (LiFePO₄) battery packs are available in 51.2V/102Ah (~52 kg, 5.22 kWh) and 153.6V/54Ah (~83 kg, 8.3 kWh) configurations.

Smarter on the Water
What sets the SE8 apart isn't just the electric drive — it's the intelligence built on top of it. Powered by BeiDou maritime-grade positioning and AI algorithms, the system turns a traditional outboard into a self-aware co-pilot.
- Autonomous cruise — uses high-precision BeiDou marine maps and AI to optimize straight-line routes for the shortest distance and lowest energy consumption, holding a set course and speed automatically.
- Electronic anchor — resists wind, waves, and current to hold the vessel precisely in place, replacing a traditional anchor while protecting fragile seabeds like coral reefs.
- 360° in-place rotation — rotate the hull on the spot with less than 2 m of drift, and halve the turning radius versus a single-propeller setup.
- AI direction hold — dampens hull sway and keeps heading steady, even in choppy conditions.
- Lure-fishing & net-casting modes — position-hold combined with adjustable forward or reverse thrust, purpose-built for anglers and working boats.
Fleet-ready by design — a built-in smart-management layer (scan-to-ride via WeChat or Alipay, flexible multi-scenario billing, real-time revenue reports, fleet-wide GPS tracking with one-tap call, automatic deposit settlement, and optional passenger insurance) turns a boat into a managed, monetizable asset.
Under the hood, the system integrates seamlessly with your existing vessel or fleet software over CAN Bus, UART, IIC, RS485, and 4G/5G cellular, so remote monitoring, cloud data exchange, and long-distance control are all supported out of the box.
Efficient, Durable, and Maintenance-Free
Every SE8 motor is paired with a deep-matched LiFePO₄ battery pack with IP67 waterproofing and a built-in Battery Management System (BMS) that guards against overcharge, over-discharge, over-current, under-voltage, short-circuit, and high temperature — while balancing cells for a long service life. Charging works from 0°C to 55°C, and discharge from −20°C to 60°C.
The result is a motor that's lighter (each unit weighs just 5–30 kg, with smaller models liftable by one hand), easier to install (standard bracket, plug-and-play), and effectively maintenance-free — no engine oil, oil filters, spark plugs, or fuel filters to replace.
The Economics: Up to 85% Lower Running Costs
Here's where the numbers get compelling. Take a typical 10-meter fishing boat with a 1-ton load, out at sea 150 days a year, covering 30 nautical miles per trip:

Add it up and the electric system saves a boat owner nearly ¥80,000 (≈$11,300) per year — an up to 85% reduction in running costs. With a typical payback period of just 150–190 days, and eligibility for regional "green vessel" purchase subsidies, the switch pays for itself in a single season.
Proven on the Water
The SE8 series isn't a concept — it's already at work in real fleets:
- A 3-meter "water train" of pontoons — a single 2.4kW unit tows a train carrying more than 24 passengers around Songshan Lake.
- A 7-meter sightseeing boat upgraded to 8kW electric drive reaches 8 knots, carries 600 kg, and cruises nearly 30 nautical miles on a single charge — zero emissions.
- A 9-meter flat-bottom boat works aquaculture waters with 270 kg of thrust, while a 12-meter, 5-ton transport boat runs fully electric with 360° rotation and autonomous cruising.
- For anglers, a hybrid fuel-plus-electric setup runs the petrol engine to the fishing grounds, then switches to a silent 2.4kW electric system for position-hold and lure fishing.
Compatible With the Boats You Already Have
You don't need a new vessel to go electric. The SE8 system is designed for 100% compatibility with existing fuel-powered boats, with a standard mounting bracket that fits most transoms. Retrofit a pair of 1.2kW motors (2.4kW total) to a 4-meter pontoon, a 5.8-meter fishing boat, or an 11-meter performance platform — and keep your old engine for top speed while the electric drive handles the quiet, efficient work.
Built on Real R&D
This is technology with serious engineering behind it. SeaEdison's development is supported by the Hong Kong Innovation and Technology Commission's Innovation and Technology Fund, co-developed with researchers from The Hong Kong Polytechnic University and the University of the West of Scotland, and protected by invention and utility-model patents. An in-house team — including post-doctoral, master's, and bachelor's engineers specializing in embedded systems, power control, and hydrodynamics — has been refining the platform since 2018.
