The Evoy Storm, a battery-powered 300hp outboard motor that its makers claim will become the most powerful to hit the water, has made its debut at the 2022 Cannes Yachting Festival.
However, what we’re looking at is a prototype build of the motor. According to Evoy, some work still needs to be done before the Evoy Storm is ready for sale to recreational boaters in need of plenty of performance, but without the emissions hangover.
The new 300hp Storm will join Evoy’s other electric motors already on sale to recreational boaters including the 90hp to 120hp (although the higher-performance rig can peak at 185hp when needed) Evoy Breeze range, and the 400hp (peaking at 800hp) Hurricane inboard motor.
The prototype Storm outboard motor is packaged quite differently to computer-generated images of the motor fitted to one of the three partner boat makers – Swedish brand Axopar, amphibious boat brand Iguana and centre console/RIB specialist Goldfish, the latter of which holds a world record for the fastest battery-powered boat on the water.
Of note, the images of the 300hp Storm fitted to the Iguana include a version that is fitted with foils to help lift the hull out of the water – important for significantly increasing the range of battery-powered boats.
The 800-volt prototype outboard motor is powered by a pair of 63kWh Kreisel batteries – the same company providing battery packs for hybrid WRC rally cars – enabling the prototype to reach a top speed of 50 knots. Evoy claims the “ground-breaking” batteries can be charged to 80 per cent of capacity in less than an hour using a rapid recharger, with a 100 per cent charge taking about 4.5 hours.
Few other details were released about the new outboard motor, although Evoy is on the record that it expects its products to have a range of around 25 nautical miles between charges, all while travelling at speeds between 22 to 30 knots – any speed lower than that and the ride is likely to become rough and wet.
The engine will be trialled on the new Axopar 25.
“The Axopar 25 is one of the rare electric boats on offer that you can take outside of sheltered waters due to its hull design and drivability, being one of the best in its size,” Evoy said.
“Another feature that sets the Axopar 25 electric prototype apart is its impressive hull efficiency.
“Axopar hulls have improved with each?generation, resulting in higher speed and more?extended range with less engine power.
“Combining this efficiency with an innovative electric engine showcases Axopar’s dedication towards creating the most comfortable drive even when presented with challenging conditions.”
According to Evoy, the prototype shows that high speeds and electrification “can go hand in hand”.
“With low consumption, impressive torque, and range, the engine is perfect for boat owners keen to go green and get every inch of speed out of their boats,” the company said.
The first Axopar to feature the 300hp outboard motor is expected to hit the market over the next eight to 12 months, depending on the pace of its development.
