Frequently Asked Questions

Spirit 2
The ePropulsion Spirit 2 is a portable electric outboard engine launched in late 2025. It delivers 2 kW of continuous power with a 3 kW Boost Mode for 60-second bursts, making it approximately twice as powerful as the Spirit 1.0 series at 2 kW and three times more powerful in boost mode. It comes stock with a 1,539 Wh Spirit Battery Ultra, features built-in hydrogeneration, a full-color display, a 45 W USB-C charging port, and a cable-free battery connection. Total weight is approximately 50 lbs depending on shaft length. Deliveries are expected to begin spring/summer 2026.
The Spirit 2 delivers 2 kW of continuous power versus 1 kW on the Spirit 1.0 Plus — double the output. The Spirit 2's battery (1,539 Wh) is about 21% larger than the Spirit 1.0 Plus (1,276 Wh). The Spirit 2 adds hydrogeneration, a 3 kW Boost Mode, a full-color display, an extendable/foldable tiller, a USB-C charging port, and a cable-free battery connection — none of which are present on the Spirit 1.0 Plus. Total system weight is similar between the two. The Spirit 2 is capable of planing small lightweight dinghies in Boost Mode; the Spirit 1.0 is not. The Spirit 2 is the recommended choice for most new buyers.
Yes. The Spirit 2 includes ePropulsion's hydrogeneration system, which recharges the battery while the boat moves under sail. It can generate up to 380 W at 10 knots, operating between approximately 3 and 16 knots. This feature was not available on the Spirit 1.0 Plus. You need to be doing at least 6 knots for the charge to be meaningful (in our opinion).
The Spirit 2 is available in extra short (XS), short (S), and long (L) shaft lengths, consistent with the Spirit 1.0 series. The remote version of the ePropulsion Spirit 2 is not available in XS. The specific shaft measurements match those of the Spirit 1.0 Plus: XS 20.7", S 24.6", L 29.5".
Spirit 1.0 Plus & Evo
Range depends heavily on throttle, hull, weight, and conditions. On EMO Electric's test platform — a 19-foot, 1,000 lb Flying Scot sailboat with two adults in calm water — the Spirit 1.0 achieved approximately 6.8 miles at full power, 8.8 miles at 75% throttle, 12.3 miles at 50%, and 19.8 miles at 25% throttle. Manufacturer figures show 7.8 miles at full power and 13.3 miles at half power. Actual range will vary by vessel.
Both share the same 1,000 W power rating and 1,276 Wh battery. The Evo adds: hydrogeneration, wireless remote steering, 1%-resolution SOC display (versus rounded to nearest 10% on the Plus), 85° max tilt angle (vs. 70° on the Plus), and tool-free tiller/remote swap.
Yes. The Spirit 1.0 Plus and Evo are compatible with ePropulsion's E60 (3,072 Wh) and E163 (8,345 Wh) external batteries, as well as qualified third-party 48V batteries. An external battery cable is required. This is one of the few portable electric outboards on the market with this expandability. The eLite and Spirit 2 are also compatible with E-Series external batteries.
The Spirit 1.0 Plus and Evo battery (Spirit Battery Plus) is buoyant and will float if dropped overboard. The ePropulsion Spirit Battery Ultra (stock battery for the Spirit 2) does not float.
Navy Evo Series
The Navy 3.0 Evo is a 3 kW (6 HP equivalent) direct-drive electric outboard running on 48V DC. Unlike the Spirit series, the Navy Evo motors do not have an integrated battery — they are powered by separate external batteries, typically the ePropulsion E60 (3,072 Wh) or E163 (8,345 Wh). The motor weighs approximately 53.6 lbs (short shaft). It features hydrogeneration and a choice of tiller or multiple remote control configurations. Available in short and long shaft.
The Navy 6.0 Evo is a 6 kW (9.9 HP equivalent) electric outboard — the most powerful motor in ePropulsion's 48V lineup. It runs on 48V and requires an external battery: ePropulsion recommends one E163 (8,345 Wh) or two E60 batteries wired in parallel. Motor weight is approximately 64 lbs (short shaft). With one E163, expect roughly 1 hour 20 minutes of run time at full throttle and approximately 2 hours 40 minutes at half throttle. The Navy 6.0 Evo uses a liquid-cooled motor design, features hydrogeneration, and supports dual remote controls for twin-motor setups. Short shaft: 25.3"; long shaft: 30.1".
The Navy 3.0 Evo runs on 48V and is recommended for use with the ePropulsion E60 (3,072 Wh) or E163 (8,345 Wh) battery. Third-party 48V lithium or deep-cycle batteries are compatible if they provide at least 62.5A continuous discharge current, though ePropulsion's BMS integration and SOC accuracy is best achieved with E-Series batteries. Battery and control (tiller or remote) are sold separately from the motor.
The Navy 6.0 Evo runs on 48V and requires either one E163 (8,345 Wh) battery or two E60 (3,072 Wh each) batteries wired in parallel. You can also use one of the new E100 batteries to power the Navy 6. A single E60 is not sufficient to power the Navy 6.0 Evo alone. Third-party batteries must provide a minimum continuous discharge current of 125A at 48V. Note that hydrogeneration is only functional with ePropulsion E-Series batteries — not third-party packs.
The Navy 3.0 Evo produces 3 kW (6 HP equivalent) and the Navy 6.0 Evo produces 6 kW (9.9 HP equivalent). The Navy 6 also has a shallow water tilt angle. Both run on 48V, both feature hydrogeneration, and both support the same Evo tiller and remote control ecosystem. Battery requirements differ: the 3.0 pairs well with a single E60 or E163; the 6.0 requires two E60s in parallel or one E163.
Yes. Both the Navy 3.0 Evo and Navy 6.0 Evo can be integrated with a standard rotary cable steering system, making them suitable for larger boats with helm stations and steering wheels. Remote throttle controls (top mount, side mount, or dual) are sold separately.
General
Both are well-regarded electric outboard brands, but differ in design philosophy. ePropulsion Spirit and Navy motors use all-metal motor housings and offer third-party battery compatibility. Both ePropulsion and Torqeedo have a standard 2-year warranty, although sometimes you can get a 3rd year with ePropulsion outboards if you register your electric outboard. At EMO Electric, we carry both brands and are happy to advise on the best fit for your specific boat and use case.
Yes. All ePropulsion 48V E-Series batteries are compatible with ePropulsion's MPPT Solar Charge Controller, allowing the battery to be topped up via solar panels. This is particularly useful for sailors on longer passages. The batteries for the Spirit 1.0 Plus, Spirit Evo, Spirit 2, and eLite can also be charged with solar.
Yes. All ePropulsion electric outboard engines are designed for both saltwater and freshwater use. Motors use high-grade anodized aluminum alloy construction with corrosion-resistant coatings. EMO Electric recommends a freshwater rinse after saltwater use, as with any marine equipment.
