What is the difference between the Spirit 1.0 Plus and the Spirit Evo?

Both are 1kW (3hp equivalent) direct-drive electric outboards using the same 1276Wh floating battery. The Spirit 1.0 Plus is the benchmark tiller-steer model for small boats. The Spirit Evo adds premium features primarily geared toward sailors and custom console builds: it supports remote throttle/steering and features hydrogeneration, meaning the free-spinning propeller actually recharges the battery while you are sailing.

Does the ePropulsion Spirit battery actually float?

Yes. It sounds like a gimmick until you drop it off the dock, but the 1276Wh lithium-ion Spirit battery is fully IP67 waterproof and positively buoyant. You can confidently swap batteries on the water without the fear of your power source sinking to the bottom.

What shaft length do I need for my boat?

Electric outboard shaft lengths don't match traditional gas outboard sizing—we call this the "one step back" rule. If you have a 15-inch transom (common on small jon boats), you need the Extra Short (XS) ePropulsion shaft. If you have a 20-inch transom, you need the Short (S) shaft. Anything over 20.7 inches will require the Long (L) shaft.

How much more powerful is the new Spirit 2?

The Spirit 2 is a massive leap in power. While the 1.0 Plus is a 1kW motor, the Spirit 2 delivers 2kW of nominal power (roughly a 5hp equivalent). More importantly, it features a 60-second 3kW Boost Mode (6hp equivalent) designed to help you punch through strong currents, heavy chop, or get a loaded boat moving quickly. On lightweight craft under 14 feet, you can see top speeds hit 9 to 13 mph.

Is the battery on the Spirit 2 different?

Yes. The Spirit 2 uses a new 1539Wh integrated battery that utilizes a cable-free, quick-connect latch system. It also features a built-in 45-watt Type-C USB port directly on the battery, acting as a portable power station to run your fish finders or charge your phone out on the water.

Is the eLite outboard powerful enough for my boat?

The eLite is a 500W motor (roughly a 1.5hp equivalent) that weighs less than 15 lbs without the bracket. It is designed specifically for ultralight setups: inflatable dinghies, square-stern canoes, and shuttling yacht tenders to and from the marina. If you need to push a fully loaded 14-foot jon boat, step up to the Spirit series. If you want the most portable, grab-and-go motor on the market, the eLite is it.

Does the eLite have a shallow water mode?

Yes, it features a one-click Shallow Water Mode that kicks the motor up to a 36-degree angle, plus an Anti-Grounding mode where the shaft is free to kick up if you strike a submerged rock or stump.

Do the Navy Evo outboards come with built-in batteries?

No. Because of the massive power output of the Navy series, they require an external 48V battery bank. We highly recommend pairing them with ePropulsion's E-Series lithium iron phosphate (LiFePO4) batteries (like the E80 or E175). Using official E-Series batteries gives you direct BMS-to-motor communication, providing exact, real-time runtime data on your display.

Can I use third-party batteries, like Power House or Epoch, with the Navy Evo outboards?

Yes, absolutely. While ePropulsion's E-Series batteries give you that seamless BMS-to-motor communication (which provides exact runtime readouts on your display), many of our builders opt for premium third-party 48V lithium setups to maximize capacity and value.

We highly recommend pairing the Navy series with Power House 48V lithium batteries or Epoch 48V marine batteries. Both are incredible, high-output options that can easily handle the heavy continuous amp draw of the Navy 6.0 Evo. Just keep in mind that with third-party setups, your outboard display will show voltage rather than a smart percentage, so you'll want to use the battery's Bluetooth app or a dedicated smart shunt to monitor your juice. For custom builds, the power density and cost-to-performance ratio of these Power House and Epoch batteries are hard to beat.

What size boat is the Navy 6.0 Evo meant for?

The Navy 6.0 Evo is a 6kW motor, offering the performance equivalent of a 9.9hp gas outboard. It draws up to 125 continuous amps at full throttle. This is the motor you want for heavier setups: pontoon boats (18-24 feet) with passenger loads, heavy 16-20 foot aluminum boats, or as a reliable kicker/primary propulsion for sailboats operating in big water. It is also the ultimate max power setup for bass boats and custom jon boat to bass boat conversions running on electric-only lakes.
