ZeroJet moves beyond electric jets with new inboard motor range

ZeroJet is expanding its electric propulsion offering with the launch of a new range of 48V inboard motors, marking the company’s move beyond jet propulsion into the wider yacht and boat market. The E22 and E45 systems are designed for applications ranging from sailing catamarans to cruising yachts and day boats, with pre-orders now open ahead of their respective launches in 2027.

Its new E22 and E45 systems will officially launch at Metstrade (02.222) but pre-orders are now open.

Delivering continuous power

The company says the E22 delivers 22kW of continuous power from an 18kg powertrain comprising the motor, closed loop cooling system and controller. Available from January 2027, the technology is suitable across applications including cruising yachts, sailing catamarans and day boats.

The larger E45 uses two motors in one housing, delivering 45kW of continuous power with motor redundancy. It remains in final prototyping and testing, with availability planned for March 2027.

“For ZeroJet, this is a significant expansion of where our technology can be used,” says James Morton, CEO of ZeroJet. “Builders and owners have asked for our motor technology in an inboard format. This range gives them that option, whether they are developing a new boat or planning an electric repower.”

48V architecture, regeneration and flexible installation options

The E22 combines an integrated inverter with ZeroJet’s Carbon Cool Technology, a carbon cooling design that manages motor temperature under sustained load. Integrating the inverter and cooling reduces the number of separate components builders need to accommodate during installation.

Both models use a nominal 48V electrical architecture, with open battery compatibility and CAN-bus communication to give builders flexibility when configuring the propulsion system alongside a vessel’s battery and electrical installation. Shaft and sail drive configurations support both new designs and engine replacement projects.

Regeneration is standard, allowing sailing vessels to recharge their batteries while under sail. This adds a charging source during passages, alongside the vessel’s other charging arrangements.

ZeroJet is bringing the range to market through its network of electrification partners. McConaghy is among the first boat builders adopting the new product line.

Starting prices are US$12,495 for the E22 and 19,495 for the E45.
