About the FM115

The FM115 is Flux Marine's production electric-outboard platform for integrated recreational boat packages and custom projects. Flux rates the current motor at 115 hp, or 86 kW, continuously with 175 hp, or 130 kW, available for short acceleration demands. The company pairs it with 84 kWh of marine battery capacity, a Garmin chartplotter running Flux software, a mobile app and a portable charging cable. Rather than publish motor-only performance, Flux shows results for complete boats from builders including Scout, Highfield, Zodiac and Flagship. That approach is useful because speed and range are properties of the whole boat. Current package examples cover pontoons, centre consoles, dual consoles and RIBs, generally around 21 to 24 feet. The system is also available for custom integrations, but battery placement, cooling, helm equipment and charging need to be engineered with the hull.

Best For

Factory-integrated boats in the 21- to 24-foot range
Planing RIBs, centre consoles and dual consoles
Custom projects supported by Flux engineering

Performance in Context

Flux's current 84 kWh boat packages typically publish 25 to 30 miles of cruising range, depending on hull and cruising speed, and 80 miles or more at low speed. Top speeds vary from about 25 mph on a pontoon to the mid-30s on lighter RIBs. These are completed-boat figures and should not be transferred from one hull to another. The 175 hp acceleration rating is short-term output; 115 hp is the continuous comparison figure.

Battery and Charging

The standard package examples use 84 kWh of lithium-ion battery capacity installed in the hull. Flux lists overnight charging from a basic connection, roughly 7.5 hours from a 220 V, 30 A supply, and about 1.5 hours for a 20-to-80-percent Level 3 fast charge. Charging time varies with site power and battery state. Flux states that the drivetrain and battery packs carry a five-year standard warranty, while hull and third-party equipment retain their manufacturers' coverage.

Availability and Pricing

Flux currently markets the FM115 through complete boat packages and custom-integration enquiries rather than a simple motor-only online price. Package pricing includes the hull, propulsion system, battery, controls, Garmin display, charging cable and app access. Buyers comparing alternatives should separate hull equipment from propulsion cost and confirm the performance test conditions for the exact model.
