What is the range of the ePropulsion Spirit 2 at cruising speed vs. full throttle?

Range on the ePropulsion Spirit 2 varies based on speed, boat type, and conditions. The figures below are approximate for a typical tender or inflatable in calm conditions:

• Full throttle (Sport Mode): approximately 8–12 km
• Cruising speed (~50% throttle): approximately 20–35 km

Because water drag increases exponentially with speed, running at half throttle more than doubles your range. For the best balance of speed and range, a cruising speed around 50–60% throttle is recommended.

If you need more range, the Spirit 2 can be connected to an E-series external battery (E60, E100, or E163) for significantly extended operation. Sailboat users can also take advantage of hydrogeneration to partially recharge the battery while sailing at 4 knots or more.
