What we do
Electrify your senses with ZeroJet
Imagine instant acceleration and power, with nothing but the sound of whipping wind and the smell of clean ocean air.
Steering that is agile and precise, a truly exhilarating ride.
With nothing but the ocean and a rushing jet stream as you look behind you, it’s hard to believe the incredible technology at work below.
Your ZeroJet-powered electric boat has become your new favourite experience.
Company's story
Our Specialty
World-leading Electric Technology
At ZeroJet we design, engineer and manufacture electric systems providing sustainable and reliable solutions.
Our systems are designed and built by world-class engineers, adding a quality that is consistent with your brand.
We invest heavily in design, development and testing, including the building of our own electric motors and bespoke jet pumps. This allows us to produce our electric jet systems to the high-quality standards required to operate reliably in harsh environments.
Product Technology
Electric Motors
Generating continuous power in an electric motor presents a significant challenge due to the amount of heat created, but the ZeroJet team overcame this through the development of an innovative closed loop cooling path. The result is a motor unit which is 61% lighter and 33% smaller per kW than existing motors on the market, giving significant performance advantages. The motor is optimised to run at the comparatively lower speeds required by the jet pump, and the simple drive line is direct drive with no gearbox which minimises maintenance.
Jet pump
Efficiency is essential when going electric. ZeroJet’s pump is specifically designed and optimised for the high-torque of an electric motor. The pump has been tuned for small boats which often travel at slower speeds (<20 knots). Traditional jet pumps are built for high-speeds and have poor efficiency at lower speeds – this is not the case with the ZeroJet system.
Battery Packs and Battery Management System (BMS)
We chose the safest type of battery cell chemistry on the market for our system and use quality third-party Lithium Iron Phosphate (LiFePO4) batteries which are mounted in our in-house built waterproof cases for protection.
The Super B batteries in our systems are rated to 3,500 charge cycles at 100% Depth of Discharge (DoD). The 5 kWh battery pack (which can be split) weighs approximately 50 kg, and the 10 kWh pack (one brick) is around 100 kg.
Our BMS monitors current and throttle input for safe operation, provides critical information on battery health and performance to optimise energy usage, and monitors the battery’s temperature to ensure it stays within safe limits.
Helm and console throttle (select systems)
The ZeroJet helm and console throttle with traditional lever operation is an electronic and mechanical unit. The electrical output signal controls the speed of the motor for forward and reverse function, while the mechanical output of the throttle controls the lowering and lifting of the reverse bucket with a cable.
The throttle level has a neutral lock position to eliminate accidental movement, and the main power-on switch is located on the base of the unit, together with the kill cord attachment point.
This assembly can be mounted on left or right side of console to best suit your vessel.
Tiller (select systems)
The ZeroJet tiller setup is perfect for smaller or open boats which don’t have a console and where maximising space is paramount. The tiller can be mounted at any height or distance on the transom and is not fixed to a certain location. The easy-to-connect cables allow you to quickly install the tiller as part of the electric jet boat system.
Tiller height can easily be adjusted by the driver and the reverse engagement lever is located on the tiller. The throttle is a standard twist throttle, making operation very intuitive compared to traditional outboards, and the kill cord attachment point is located on top of the tiller.
