About the FM100 Electric Outboard

The FM100 is Flux Marine's earlier 100 hp-class electric outboard platform. Flux identified the powertrain at 75 kW continuous, with short-duration output around 112 kW in production boat applications. It was developed as an integrated system rather than a stand-alone motor: the outboard, modular marine battery, helm display, controls and charging hardware were designed to work together. Current Flux consumer material has moved to a 115 hp continuous outboard with 175 hp acceleration power, so the FM100 should be understood as a previous-generation model rather than the company's current retail specification. It remains relevant for used boats and earlier installations, and Flux has continued to refer to the FM100 in a recent electric speed-record project. Prospective buyers should identify the exact motor version and software on any boat advertised with an FM100 instead of assuming it matches the current 115 hp package.

Performance in Context

Boat-level performance cannot be assigned to the motor alone. Flux published examples using an 84 kWh pack, including a 24-foot GFX Stealth with a 24 mph top speed and about 30 miles of range at cruising speed. Those results belong to that hull, load and test setup. Current Flux packages quote different speeds and ranges for pontoons, RIBs and centre consoles using the newer 115 hp system. Used FM100 buyers should request sea-trial data for the actual boat and verify usable battery capacity and software-reported health.

Battery and Charging

Production integrations paired the motor with Flux's modular, liquid-cooled marine battery system; a common configuration used three 28 kWh modules for 84 kWh total. Flux supports 120-volt, 240-volt and DC fast charging in its integrated systems. An official FM100-equipped boat example lists 6.6 kW AC and 50 kW DC charging, with 20-to-80-percent times of 7.5 hours and one hour respectively. Charge performance depends on the installed inlet, battery generation, temperature and shore supply.

Availability and Pricing

Flux no longer presents the FM100 as its current retail model. New boat packages use the Flux 115 hp outboard, while FM100 availability is limited to existing boats, legacy projects or direct arrangements with Flux. The former directory package price has been removed because it cannot be applied reliably to a motor-only purchase or a current boat package.
