Where the Spirit 2 Shines

The Spirit 2 is highly versatile, but its absolute sweet spot is on lightweight, solo-person inflatables and skiffs.

When paired with a lighter craft, this motor takes full advantage of its higher RPM range. In our testing, switching into Boost Mode gives you just enough extra muscle to pop these small boats up on plane, hitting speeds of 9–12 mph. Once you pull the throttle back to a highly efficient cruising speed of 5–7 mph, the battery efficiency skyrockets, giving you a much longer overall traveling range on a single charge.

How does it compare to the older Spirit 1.0 Plus?

If you are putting the Spirit 2 on a larger, heavier craft, the top-speed advantage over the older Spirit 1.0 Plus becomes more minimized because of the hull weight. However, even on a heavier boat, the upgraded efficiency and power of the Spirit 2 will still typically outperform the older 1.0 Plus by 1–3 mph while giving you a much smarter, cable-free user experience.

Performance and Real-World Usability

The ePropulsion outboard system emphasizes efficiency and simplicity. Unlike traditional petrol engines, it eliminates fuel consumption and noisy operation while providing smooth movement on the water.

1. Power Output: A True 5HP Petrol Equivalent

The ePropulsion sppirit 2 delivers adequate thrust for small to medium vessels. It performs well in calm lakes, rivers, and coastal areas, offering steady cruising speeds and responsive acceleration. Although it does not compete with high-speed petrol motors, electric propulsion excels in controlled navigation and quiet operation.

Sport mode enhances power when extra acceleration is needed, such as navigating waves or carrying additional weight. This feature gives users flexibility without sacrificing energy efficiency. For recreational boaters, the balance between speed and quiet operation often proves more valuable than raw top-end velocity.

2. Whisper-Quiet Performance for Anglers

Electric propulsion eliminates engine noise and emissions. With the outboard motor, users can enjoy nature without disturbing wildlife or fellow boaters. This is especially beneficial in protected waterways where environmental regulations restrict fuel-powered engines.

Quiet operation also enhances fishing experiences by reducing disturbance in the water. Many anglers report improved success because fish are less likely to scatter when the motor is silent.

3. Cordless Battery & Real-Time Smart Display

Battery life depends on throttle usage and environmental conditions. At moderate speeds, users can expect several hours of operation, sufficient for most recreational outings. Because electric motors do not consume fuel, running costs are lower, and maintenance requirements are minimal.

Charging is straightforward with standard outlets, allowing users to recharge between trips. Planning ahead ensures the motor is always ready for use. Some boaters choose to carry a backup battery for extended excursions, increasing versatility.

4. Cost Breakdown: Is the Spirit 2 Price Worth It?

Although initial costs may be higher than small petrol motors, the outboard motor offers long-term savings. Maintenance is minimal, and there are no fuel expenses. Over time, these savings can offset the purchase price.

Electric motors also have fewer moving parts than combustion engines, reducing the likelihood of mechanical failures. Routine maintenance typically involves cleaning and occasional inspections rather than complex repairs.

Frequently Asked Questions

Q: Can the ePropulsion Spirit 2 get a boat on a plane?

A: Yes, under the right conditions. While the motor runs at a steady 2kW (5HP equivalent), switching it into its 3kW Sport Boost Mode (6HP equivalent) provides a massive temporary kick of thrust. In testing on a lightweight 11.5-foot aluminum hull or inflatable skiff, this temporary surge is enough to get a light load over the hump and onto a plane.

Q: What exactly is Boost Mode and how does it work?

A: Sport Boost Mode is a high-power feature that allows the Spirit 2 to jump from its nominal 2kW output up to 3kW. It is designed to run for up to 60 seconds per use to help you accelerate past heavy currents or combat strong wind. After the 60-second burst, the system enforces an automatic safety cooldown period to keep things from overheating.

Q: Does the new Spirit 2 battery float?

A: No. Unlike the original Spirit 1.0 Plus battery pack which was buoyant, the upgraded 1539Wh Spirit Battery Ultra is packed with dense cells and does not float. Because the battery lacks positive buoyancy, we highly recommend sliding it securely into the motor head bracket and throwing the side sliding locking handle before you leave the boat ramp.

Q: How long does the Spirit 2 battery last on a single charge?

A: It entirely depends on how heavy your throttle hand is. On an 11.5-foot aluminum test hull under calm lake conditions, your runtimes break down like this:

Sport Mode Boost (3000W):Limited to 60-second high-torque bursts.
Full Speed (2000W):Delivers 54 minutes of continuous runtime.
Half Speed (1000W):Extends your on-water time to 1 hour and 48 minutes.
Cruise Speed (500W): Sips power efficiently for a clean 3 hours of runtime.
Trolling / Fishing Speed (100W):Sips minimum power for up to 15 hours of continuous tracking.

Q: Can I use external batteries with the Spirit 2?

A: Yes, absolutely. The Spirit 2 plays perfectly with the ePropulsion 48V architecture, meaning you can plug straight into external E-Series lithium batteries (like the E60 or E100 packs) using an external power cable to easily extend your runtime into multi-day camping or fishing trips.

Q: What comes included in the box?

A: It depends on if you purchase the Tiller Version or the Remote version. The standard Tiller kit includes the 2kW motor unit, a detachable transom mounting bracket, a 1539Wh Spirit Battery Ultra, a Spirit Battery Charger Ultra, a magnetic smart kill switch with a wristband, and your user manuals. (Note: The Remote version swaps the tiller handle for a remote steering linkage and installation kit)
