For many boating enthusiasts, when switching from traditional fuel‑powered outboard motors to electric outboard motors, or choosing electric outboard motors, the most common dilemma is power selection. Underpowered motors may struggle to propel the boat, resulting in poor navigation performance or even failure to operate normally. Overpowered units lead to excessive costs and resource waste. As a mainstream brand in the electric outboard motor market, FUBER offers a comprehensive product line covering all‑scenario demands from lightweight portable units to heavy‑duty workhorse motors. To accurately select the power rating of FUBER electric outboard motors, the key lies in understanding "equivalent horsepower", determining your boat size and load capacity, and clarifying your primary usage scenarios. This article elaborates on these dimensions to help you easily find the most suitable power unit.

I. Understand the Power Terminology of Electric Outboard Motors

Before selection, we must clarify a core concept: the relationship between kilowatts (kW) and horsepower (HP/PS). Traditional fuel‑powered outboards are rated by horsepower, while electric outboard motors scientifically use kilowatts as their rated power unit.

There is a basic conversion formula between the two. However, due to the fundamentally different power output characteristics of electric motors and combustion engines, the theoretical conversion value does not fully match real‑world water propulsion performance.

Theoretical Conversion: 1 kW ≈ 1.36 metric horsepower (PS).

Practical Performance: Electric motors deliver high torque at low speeds, generating peak torque instantly with no mechanical losses or transmission delays found in fuel engines. Therefore, a 4kW electric outboard motor often performs comparably to a 6‑7 HP fuel‑powered outboard in acceleration, towing, and low‑speed cruising.

Simply put, electric outboard motors deliver greater perceived power than fuel‑powered motors of the same rated power under low‑speed and heavy‑load conditions — one of their key technical advantages.

II. Full Analysis of FUBER Mainstream Models & Boat Compatibility

FUBER’s electric outboard motor product line is clearly structured, with power tiers from Global 1.5 to Global 8.0 covering all needs from single‑person kayaks to large workboats. Below we analyze the applicable scenarios for each power rating paired with specific boat types.

1. Lightweight Performer: Global 1.5 (1.5kW, equivalent to approx. 3‑4 HP)

This model is the "portable gem" in FUBER’s lineup, defined by extreme lightweight design.

Core Specs: Rated power of 1.5kW, ultra‑lightweight for easy single‑person installation and transport.

Ideal Boat Matches:

3‑4.5m inflatable boats, small fishing boats or dinghies: Lightweight and low‑resistance vessels where the G1.5 delivers a comfortable cruising speed of 6‑10km/h, perfect for single‑ or dual‑person angling and short trips on calm inland lakes and reservoirs.

Recommended total weight (hull + passengers + gear): Under 400kg. Optimal performance in light‑load conditions (below 250kg) for extended range and higher speed. Power becomes insufficient when fully loaded or with boats over 5m long.

In short: Top choice for short‑haul portability and light‑load trips, ideal for kayaks, small inflatable rafts or auxiliary power for sailboats.

2. Balanced All‑Rounder: Global 3.0 / G3.0 (3kW, equivalent to approx. 6‑8 HP)

A popular pick among lure and recreational anglers, striking an excellent balance between power, weight and portability.

Core Specs: Rated power of 3kW with a total weight of only 8kg.

Ideal Boat Matches:

2.0‑3.0m inflatable boats and hard‑bottom fishing boats: The G3.0’s sweet spot. It delivers stable, ample power for single‑ or dual‑person angling with full gear in calm water. Its ultra‑quiet operation is ideal for lure fishing without spooking fish.

Small dinghies under 3.0m: Sufficient power for single‑person light‑load near‑shore use in calm water; underpowered for dinghies over 3.3m or dual‑person heavy‑load use, unable to reach high‑speed planing.

In short: Perfect match for lure boats and small inflatable boats, cost‑effective with superior quiet performance.

3. Versatile Workhorse: Global 4.0 (4kW, equivalent to approx. 8‑10 HP)

The robust mainstream choice for larger hulls and higher load demands.

Core Specs: Rated power of 4kW (theoretical 5.4 HP), with real‑world propulsion equivalent to a 6‑7 HP fuel‑powered outboard.

Ideal Boat Matches:

4‑7m medium‑sized speedboats, lure boats and recreational sightseeing boats: This power rating delivers confident cruising capability with sufficient power reserve against mild currents and waves.

Scenarios requiring both speed and load capacity: Compared with the G3.0, the G4.0 maintains higher speed and maneuverability with more passengers or equipment onboard.

In short: Ideal power unit for medium‑sized recreational boats with ample power reserve for diverse water conditions.

4. Professional & Commercial Grade: Global 6.0 (6kW, equivalent to approx. 12 HP) & Global 8.0 (8kW, equivalent to approx. 15 HP)

These two models enter the professional and commercial segment with high power output for advanced applications.

FUBER G6.0 (6kW):

Ideal for professional angling, private water recreation and light rescue/commercial applications. Its 12‑HP equivalent power easily drives full‑size lure boats for long‑distance cruising on open water. Featuring ultra‑quiet operation and zero emissions, it provides a near‑perfect power solution for boat anglers.

In short: Premium choice for professional anglers and quality‑focused recreational users with well‑balanced power, quietness and range.

FUBER Global 8.0 (8kW):

Ideal for heavy‑load high‑speed boats and various workboats. The flagship power unit in FUBER’s civilian lineup, capable of propelling boats up to 3 tons at high speeds, suitable for water operations, official patrol and other high‑demand power‑intensive applications.

In short: Top choice for powerful performance and multi‑purpose work, engineered for large boats and demanding tasks.

III. Ultimate Selection Guide – Quick Reference Table

For intuitive decision‑making, the summary table below offers clear guidance:

Extra Tips:

Battery capacity matters more than power rating: Choosing the right power is only the first step; range depends on battery capacity. Opt for high‑capacity battery packs or multi‑battery expansion solutions for long‑distance navigation. For models like the G3.0, a 24V 105Ah+ lithium‑ion battery is required for all‑day angling trips.

Consider real‑world operating conditions: If navigating fast‑flowing waters, offshore areas or choppy conditions, add 20‑30% extra power reserve to counteract power losses in harsh environments.

Check shaft length: Ensure the outboard shaft length matches your transom board. Deep‑V hulls typically require long‑shaft versions for full propeller submersion.
