A dedicated 3HP electric outboard motor is engineered for primary boat propulsion, delivering higher top speeds (6.6 mph) and lightweight design compared to standard trolling motor setups. In contrast, a 24V 70lb trolling motor system weighs 128 lbs with lead-acid batteries, maxes out at 4.0 mph, and is built primarily for low-speed maneuvering while fishing. At matching speeds, the Spirit 1.0 Plus delivers over three times the runtime.

Primary Propulsion vs. Precise Positioning

If you fish electric-only reservoirs or are outfitting a tiny boat, you’ve likely considered using a heavy-duty 3hp trolling motor as your main source of power. While trolling motors excel at low-speed maneuvering while casting, they lack the propulsive thrust profile and efficiency required of a primary 3 hp electric boat motor.

Below, we break down real-world data from a side-by-side water test between a 24-volt, 70-pound thrust Minn Kota Traxxis trolling motor and the ePropulsion Spirit 1.0 Plus  to give you the hard facts.

Weight & Portability

The first major advantage of a dedicated ePropulsion motor is the total rig weight on your boat:

• ePropulsion Spirit 1.0 Plus:The total weight of the motor, including its integrated 1,276Wh floating lithium battery, is just 42 pounds.
• Minn Kota Traxxis (24V Setup): Running a 70lb thrust motor requires two 12-volt deep-cycle lead-acid batteries. Combined with the motor, the entire setup weighs 128 pounds exactly three times the weight of the Spirit 1.0 Plus.

For jon boats, skiffs, and tenders where every pound impacts draft and stability, a dedicated 3hp electric outboard motor keeps your craft balanced and easy to haul.

Top Speed & Run Time (The Hard Facts)

On-water testing reveals significant performance differences between a 24V trolling motor and a 1kW electric outboard:

Battery Diagnostics & Lifespan

• Real-Time Monitoring: The tiller handle on the Spirit 1.0 Plus features a digital display showing real-time power draw in watts, battery percentage, voltage, and remaining run time in minutes. The Traxxis features a basic 4-light meter that is only accurate when the motor is stopped.
• Brushless Motor Technology: The Spirit uses a brushless DC motor that maintains performance over time without wearing down. Brushed trolling motors experience efficiency loss as internal brushes degrade.
• Battery Lifecycle:Standard AGM deep-cycle batteries typically offer 200–300 charge cycles. The Spirit's lithium-polymer battery is rated for 800 cycles—delivering up to four times the usable service life.

Comparing Models: Spirit 1.0 Plus vs. Evo vs. Spirit 2

If you decide an outboard fits your boat best, compare theseePropulsion Spirit Plusconfigurations:

• Spirit 1.0 Plus:Classic tiller control with high portability—ideal for jon boats and skiffs.
• ePropulsion Spirit 1.0 Evo:Adds hydrogeneration capability for sailing and options for remote throttle controls.

Selecting Shaft Length: The Short Shaft Advantage

To ensure optimal speed and prevent propeller ventilation or drag, match your motor shaft to your transom height:

Final Cost Analysis

While a 70lb trolling motor setup with AGM batteries costs roughly $920 compared to the ePropulsion Spirit 1.0 Plus at ~$1,999, upgrading that same trolling motor setup with lithium batteries to match the Spirit's weight and lifespan pushes your total cost higher than buying the complete ePropulsion outboard package.

When you account for weight savings and runtime, investing in an ePropulsion 3HP electric motor gives you significantly more efficiency per dollar spent.

With an authorized  ePropulsion Spirit 1.0 for sale  at TBNation, you get higher top speeds, three times the runtime at cruising speed, an 86-lb weight reduction, free shipping, and a 3-year warranty built for long-term performance.

Frequently Asked Questions

Can I use the ePropulsion Spirit 1.0 Plus as a trolling motor for fishing?

Yes, but it functions primarily as your main propulsion engine rather than a bow-mount positioning tool. At 10% throttle (~100W), the Spirit 1.0 Plus can quietly push your boat at ~3.2 mph for up to 12.5 hours, making it excellent for slow trolling across large bodies of water.

Is a 3HP electric outboard really equivalent to a 3HP gas engine?

Yes, in terms of propulsive thrust. The 1kW brushless motor generates instant torque, delivering the same pushing power as a 3 HP gas outboard to handle craft up to 1.5 tons (jon boats, skiffs, tenders, and inflatables).

How much weight do I actually save switching from a 24V trolling motor setup?

You save roughly 86 pounds. A 24V trolling motor paired with two group-27 lead-acid batteries weighs around 128 lbs, whereas the ePropulsion Spirit 1.0 Plus weighs just 42 lbs total (including the motor and integrated battery).

Why does the ePropulsion Spirit 1.0 Plus get 3x the runtime at matching speeds?

Higher battery efficiency and motor design. Lead-acid batteries used in traditional trolling motor setups suffer from rapid capacity drop under heavy amp draws (Peukert's Law). The Spirit’s 1,276Wh lithium-polymer battery combined with a brushless motor maintains peak efficiency continuously.

Can I hook up an external battery to extend my range?

Yes. While the Spirit comes with a 1,276Wh detachable top-mount battery, you can also plug directly into an external ePropulsion 48V E-Series lithium battery pack for extended long-distance cruising.
