ePropulsion kMax 2200 Electric Outboard for Kayaks
A stern-mounted 2.2kW electric propulsion system built for large fishing kayaks. The ePropulsion kMax 2200 pairs a high-output motor with a modular 48V LiFePO4 battery platform that scales from one portable pack up to four for over 4kWh of range — turning your kayak into a fully capable electric fishing boat.
Why This Motor Is the Right Choice for Your Kayak
- Up to 2.2kW peak output — demonstrated on-water speeds near 7.8 mph on a large fishing kayak
- Modular battery design — run one 1,024Wh pack for lighter kayak setups, or connect up to four in parallel for 4,096Wh of total energy
- Fish Mode — caps output around 200W for precise, low-speed kayak control while working structure or shorelines
- Fast charging — a single battery can go from empty to full in as little as two hours
- Bluetooth app connectivity — monitor charge level, track trip data, and run diagnostics from your phone
- IP67-rated battery housing built for marine use on the water
- Rated for up to 2,800 charge cycles at 80% health
- Single keyed cable connection per battery for simplified wiring on your kayak
- Designed for wide, stable fishing kayaks (e.g., Bonafide XTR-class hulls) with sufficient stern structure
