Momentum M6 Electric Outboard Motor

Key Features & Benefits

• Optimized for Torque: While it shares a form factor with the M10, the M6 is geared specifically for applications where pushing power and long-range efficiency matter more than top-end planing speed.
• Ultra-Lightweight & Portable: The motor on its own weighs only 48 lbs—actually lighter than most comparable 9.9 HP gas motors! This weight advantage improves boat handling by reducing mass at the stern.
• Quick-Release Transom Bracket: Features a unique, independent motor clamp (13.2 lbs) that stays mounted to your boat. This makes mounting and dismounting the primary motor unit incredibly easy for one person.
• Single Cable Connection: A fully integrated "Plug & Play" cable houses both power and data connections, eliminating the need for complex wiring or multiple battery connections.
• Integrated Trip Computer: A high-contrast color display built into the multi-position tiller provides real-time GPS speed, wattage output, and accurate remaining range calculations.
• Intelligent Safety: The CAN-Bus interface coordinates the motor, throttle, and battery, featuring a magnetic kill switch to ensure safe operation in harsh marine conditions.

• Short Shaft (15"): 39 cm shaft length — Recommended for standard short transom boats, dinghies, and tenders.
• Long Shaft (20"): 52 cm shaft length — Recommended for taller transoms, deep-V workboats, and sailboat auxiliary power.
