The electric motor for boats represents the new generation of propulsion: clean, quiet, economical. Powered by batteries, electric motors transform the navigation experience while maintaining ecosystems.
The key advantages of the electric boat motor
Whether you are a boater, fisherman or professional, marine electric propulsion offers concrete benefits from the first time you sail.
Silent browsing
Total silence at sea. Great for fishing, wildlife viewing, and comfort on board.
Zero direct emissions
No release of CO₂ or hydrocarbons into the water. Authorized access to Natura 2000 areas.
Substantial savings
€0.50 to €2 of refill for 4 hours of navigation, compared to €15 to 40 of gas. No draining.
Immediate couple
Maximum power from the start. Precise maneuvers in port, smooth acceleration.
Minimal maintenance
No drain, no filter, no carburetor. First ARION interview after 20,000 hours
Increased longevity
3 to 5× longer lifespan than internal combustion engines. Resale value preserved.
For a 4-hour outing, count around €0.50 to €2 for electricity against €15 to 40 for gas. Over a season, the savings can exceed several thousand euros — not to mention avoided maintenance.
Electric propulsion in figures
-80% energy vs thermal cost
-56% GHG emissions vs buying a new one

KRONOS & ARION: two ranges, all boats
Weenav, a French specialist in marine electric motorization, offers two complementary ranges covering all boats.
OUTBOARD
KRONOS
First high-powered 100% electric outboard designed and assembled in France. Weenav reaches a historic milestone in the nautical industry with its KRONOS engine. Where theelectric motors traditional ones were reducing their performances, KRONOS delivers 300 horsepower of continuous power, constant, with absolutely remarkable performance peaks reaching 408hp. This technical feat redefines market standards and opens a new era for sporty electric navigation.
Power 80 (59 kW) to 300 hp continuous (220 kW)
Onboard charger 22 kW integrated
Fast charge CCS2 — 20→ 90% in 20 min
Navigation Garmin co-developed
Battery Zyonix by PowerTech
Installation Plug & Play
INBOARD
ARION
Compact, lightweight and powerful inboard motor for large boats. The ARION engine develops powers of up to over 400 horsepower, with a engine efficiency reaching 97%. This remarkable efficiency transforms each kW into pure propulsion, where internal combustion engines lose a considerable part of energy in heat and friction. Maximum torque is available instantly from the start, offering unparalleled steering responsiveness and absolute fluidity in all phases of navigation.
ARION can also be configured as Hybrid series, thus offering maximum flexibility to respond to all browsing profiles. This option combines the advantages of electric propulsion (silence, instantaneous torque, zero emissions at anchor) with the extended autonomy of an auxiliary thermal generator.
Power 50 (37 kW) to 400 (295 kW) hp continuous
Integration Compact in hold
Compatibility Electric & hybrid
