What this video covers
ZeroJet Limited, a New Zealand company founded in 2014, makes 48V electric jet propulsion systems for tenders and rigid inflatable boats.0:10 CEO James explains the 48V architecture choice as deliberate: lower voltage reduces cost, simplifies installation certification, and builds consumer confidence, accepting a few per cent efficiency loss in exchange for a price point competitive with 20–30 hp petrol outboards.1:02 The jet drive eliminates an exposed propeller, enabling operation in shallow water, over reefs and rocks, and in confined areas where propeller strikes are a constant risk.2:48 ZeroJet's core engineering claim is that its water jet is optimised for 16 knots and outperforms most propellers at that speed — a reversal of the conventional efficiency curve, which normally favours propellers below 30 knots and jets only above 40.3:36 The unit uses a direct-drive motor with no gearbox to maximise efficiency and minimise size.4:01 James frames the commercial goal explicitly: high-volume sales at accessible prices, not niche premium positioning, are what will drive meaningful adoption of electric propulsion in small boats.1:44
