Though electrical motors do assist kayaks combat headwinds and currents, in addition they add appreciable weight, complexity and the potential for getting snagged in weeds. The FluxJet system is designed to alter that, with a sub-5-pound electrical jet drive module that seamlessly suits into the hull of a purpose-built kayak.
At present in useful prototype kind, FluxJet is being developed by California firm FluxJet Marine, which is a subsidiary of Kymera. The latter agency is finest recognized for its Kymera Body Board, a private watercraft that makes use of an electrical jet drive system to take prone-positioned riders as much as a prime velocity of 20 mph (32 km/h).
Six years in the past, CEO Jason Woods and his crew set about simplifying that system by lowering the variety of elements utilized in it – together with its dimension, value and weight – whereas boosting its efficiency. FluxJet is the recently-unveiled results of that effort, and it may finally discover use not solely in physique boards and kayaks, but additionally in small watercraft of any sort … see the take a look at under.
“We realized that the traditional configuration of motor plus driveshaft plus seals plus bearings plus jet pump had essentially remained unchanged for 50-plus years,” Woods tells us. “So we set out with a clean slate and took the entire drive again to first ideas – most critically beginning with ‘the very best element isn’t any element’ technique.”
FluxJet does certainly have a lot fewer elements than its predecessor, and what’s left over is packaged right into a single self-contained unit that may simply be faraway from the boat (and reinstalled) for servicing. Importantly, as an alternative of utilizing a motor to spin up a driveshaft that spins up an impeller, the system merely surrounds the impeller with a ring-type electromagnetic motor.

What’s extra, FluxJet is totally submerged … there are not any air pockets wherever within the setup. Woods says this association reduces vibrations and working noise, boosts the switch of torque into the impeller blades, and helps cool the motor at excessive output ranges.
An extra benefit lies within the placement of the impeller blades.

In most jet pumps, the impeller blades spin individually from the within partitions of an unmoving metallic ring which surrounds them. If small objects comparable to grains of sand get sucked in and caught between a kind of blades and the ring wall, the impeller could jam. What’s extra, such actions can progressively put on down the ends of the blades, reducing their effectivity.
This reportedly is not an issue within the FluxJet system, because the the blades are related to the ring, which rotates alongside with the impeller. Not solely is there now not a spot for sand to get caught in, however the blades are additionally held extra inflexible by way of their connection to the ring. Moreover, Woods tells us that the spinning ring’s transferring floor helps push extra water by the system, additional boosting its output.
“The primary take a look at unit we constructed weighed in at simply 4 lb [1.8 kg] and will put out 5,000 watts constantly with higher effectivity than the present 5-kW drive system within the boards,” he states.
“The subsequent items we constructed have been 15- to 25-kW and weighed simply 13 lb [6 kg]. For comparability, a primary 12-volt trolling motor you would possibly placed on a small boat/kayak with a prime velocity of three to 4 mph [5 to 6 km/h] will vary from 19 to 40 lb [8.6 to 18 kg] relying on the thrust and options. Our 13-lb Fluxjet was capable of push a small boat effectively over 20 mph [32 km/h] with a unit that’s roughly the scale of a soccer.”

Within the present fishing-kayak-integrated demo, steering is managed by way of two cabled foot pedals which flip the FluxJet’s vectored-thrust nozzle forwards and backwards – this implies there is no rudder to get caught in weeds or scrape on the underside. The throttle takes the type of a recessed thumb swap, which could be mounted within the cockpit to both aspect of the seat – the battery is positioned beneath the seat.
FluxJet was formally unveiled final week on the iCast 2025 fishing gear expo in Florida, the place it received the Greatest in Present award. Plans now name for the expertise to be built-in into the purpose-built US$2,999 FluxJet Kayak, which will likely be accessible for preorder as of Aug. 1st.

Measuring 132 inches lengthy by 35 inches extensive by 12 inches excessive (3,353 by 889 by 305 mm), the 88-lb (40-kg) fishing kayak will use a 1,000W FluxJet drive to succeed in a prime velocity of over 6 mph (10 km/h). Relying on battery capability, one cost ought to reportedly be good for as much as 16 hours of runtime.
“I actually anticipated individuals to be extra skeptical, however they clearly understood what we’re going for,” Woods tells us about his reception at iCast. “A clear easy kayak that works proper out of the field and may get into tremendous shallow water.”
