Flux Marine debuts 115 HP electric outboard in Miami with repower-focused tweaks

Flux Marine used Miami International Boat Show week to roll out a refreshed 2026 iteration of its 115-horsepower electric outboard platform and to press the company’s repower play. The FM115 was on display at booth MB4616 inside the Miami Beach Convention Center, and show attendees could sign up for sea trials aboard a Scout 215 XSF staged at Venetian Marina and Yacht Club during the Feb. 11–15 event.

The company presented the FM115 around a consistent sustained rating: Flux’s motor is rated at 115 hp (86 kW) for continuous operation, a figure cited by Powerandmotoryacht and Soundingsonline. Sources diverge on burst power, with Powerandmotoryacht reporting roughly 175 hp peak and Soundingsonline reporting 150 hp peak; published coverage frames peak as a 150–175 hp range pending an official spec-sheet confirmation from Flux. Flux’s modular battery architecture is clearer: three 400-volt, 28-kWh modules form the pack that powers the drive system.

Flux emphasized serviceability and real-world durability during the show. Soundingsonline reported nearly two years of field testing aboard boats and a 1,300-hour wide-open-throttle run in a test tank with no maintenance issues. Flux’s closed glycol-circulation cooling system moves heat through passages in an aluminum anti-ventilation plate rather than relying on seawater cooling, a design Soundingsonline says removes the need for post-saltwater flushing or winterization.

On the engineering side, Nationalfisherman quoted Venditti describing Flux’s in-house telemetry and software work: "Our battery management system is built in-house," and "The Flux motor is also modular in its design. The top section we call the power head. It includes the charger, the inverter, and the motor controller. The middle section holds the electric motor, and the lower unit is the belt housing and the propeller." Venditti also noted a cadence of data transmissions back to Flux of "every 10 to 15 seconds" and integration that can surface most efficient speed on Garmin displays.

Sea trials and partner boats illustrated intended use cases. Soundingsonline’s trial in Newport aboard a Highfield 660 RIB with the FM115 exceeded 25 knots at top end, delivering quick acceleration and near-silent operation. Powerandmotoryacht and Burlingtoncountytimes highlighted Scout 215 XSF demonstrations in Miami aimed at showing planing, higher-horsepower applications for recreational buyers.

Flux framed the 2026 update as manufacturing and system-level tweaks to scale production. CEO Ben Sorkin said, "The 2026 system reflects how we are evolving the Flux platform to support scale," and added that the focus is on "delivering consistent performance and reliability as we increase production to meet demand, without changing the fundamental experience our customers expect." Founders Daylin Frantin, Jon Lord and Sorkin built the company after roughly 10 years of R&D and a reported $30 million investment; Soundingsonline noted about 50 employees and a 40,000-square-foot Bristol, Rhode Island manufacturing hub.

Repower logistics remain conservative: Powerandmotoryacht reported standalone installations currently limited to Flux’s Bristol facility and Highfield’s shop in Cadillac, Michigan, with "Fluxifications" taking about 4 to 6 weeks for now. Nationalfisherman’s Venditti said customers were impressed that a Highfield-plus-Flux package could be assembled for about $120,000, while Flux continues expanding production capacity to shorten lead times and broaden installation options.
