3Bros ONE

We are pleased to present you the first on the market and unique 3Bros ONE water go-kart. Its helmsman, like a racing driver, sits low in a bucket seat, keeps a steering wheel in his/her hand, and on the right, a throttle handle. After a few seconds from the start, 3Bros ONE already planes on the water with a speed over 30km/h. Equipped with an engine 9.9hp, or 15hp that in many EU countries does not require a motorboat license to operate.

Due to the width of the hull, and low COG 3Bros ONE ensures a feeling of confidence, both when overcoming waves, as well as in sharp turns. It is impossible to flip it over at normal exploitation conditions. Bucket seat keeps you firmly inside. 3Bros ONE is also unsinkable. Basic equipment includes a fire extinguisher and emergency paddle.


Even beginners will not have problems with operating 3bros ONE. It is equipped with electric starter, car-like steering wheel, control box, and basic gauges informing about revs, fuel level, time of operation and battery charging.


Big onboard storage compartment can be used to take some personal stuff for longer trips, electric bilge pump helps to get rid of any water that gets inside during hours of fun, 19liter fuel tank assures up to 5 hours operation autonomy (on 9,9hp engine)


Electric engines can be installed for the areas where combustion engines are not allowed. They can range from small (like ePropulsion SPIRIT 1.0) to bigger (like EZ S20) assuring plane on the water. But even combustion engine usage in a full speed plane consumes from 3 to 8 times less fuel compared to jet-ski.
