Why the HARMO H3.1XSPB Excels: Deep-Water Capability, Precise Maneuvering, and Zero Emissions

For boaters who demand silent operation, exceptional control, and deep-water capability for heavier or taller vessels, the Yamaha HARMO H3.1XSPB, in fact, stands out as a true game-changer. Primarily, its 25-inch extra-long shaft ensures optimal propeller submersion on boats with higher transoms. Therefore, it provides consistent thrust and efficiency even in choppy conditions. Moreover, the innovative rim-drive electric motor design, unique to HARMO, positions the motor around the outside of the impeller. As a result, this allows for a larger, more efficient impeller, generating significant static thrust (227 lbs) with minimal cavitation. In addition, the full integration with Helm Master® EX, including joystick control and Digital Electric Steering (DES), offers an impressive 140-degree steering angle. This, consequently, provides incredibly crisp and precise maneuvering, even allowing lateral movement in twin configurations.

Why the HARMO H3.1XSPB Excels (Continued)

Beyond that, the H3.1XSPB operates on a 48-volt system, compatible with dedicated Yamaha lithium-ion batteries or approved conventional 12-volt batteries (configured for 48V). Furthermore, its inherent electric nature means zero exhaust emissions and virtually no noise or vibration. Naturally, this makes it perfect for peaceful cruising and stealthy fishing. Therefore, the HARMO H3.1XSPB consistently delivers powerful, precise, and remarkably quiet performance, while being an environmentally responsible choice for modern boating.

Core Features of Your Yamaha HARMO H3.1XSPB Electric Outboard

Fully Electric Propulsion

The H3.1XSPB is a fully electric propulsion unit. This means, for instance, it produces zero emissions at the point of use and operates with near-silent efficiency. Consequently, it allows boaters to fully appreciate the sounds of nature, from wildlife to gentle waves, without engine noise.

Innovative Rim-Drive Technology

At the core of the H3.1XSPB is its unique rim-drive electric motor. This design, for example, mounts the motor around the impeller’s outer edge. Therefore, it maximizes thrust and minimizes drag, leading to superior pushing power and efficiency compared to traditional designs.

Equivalent to 9.9 Horsepower

The H3.1XSPB system delivers 3.7 kilowatts of power, which translates to the equivalent of a 9.9 horsepower gasoline outboard. As a result, it provides ample static thrust (227 lbs / 102 kgf) for a variety of small to mid-sized boats, ensuring responsive acceleration and reliable performance.

Extra-Long (25-inch) Shaft

The “X” in H3.1XSPB signifies an extra-long 25-inch shaft length. This makes it ideal for vessels with higher transoms, such as larger sailboats, certain pontoon boats, or specific commercial applications. Ultimately, it ensures the impeller remains properly submerged for optimal performance.

Advanced Control with Helm Master® EX Integration

The H3.1XSPB is fully integrated with Yamaha’s cutting-edge Helm Master® EX boat control system. This integration, for instance, offers advanced features like intuitive joystick control, SetPoint™ positioning, and Autopilot™ capabilities. Therefore, it provides unparalleled precision for docking, holding position, and automated navigation, enhancing overall convenience and confidence.

Digital Electric Steering (DES)

The H3.1XSPB features Digital Electric Steering (DES), providing an immediate and precise response to boater inputs. This technology, for example, enables a wide steering angle (up to 140 degrees), allowing for incredibly sharp handling, including rotating a single-engine boat within its length and true lateral movement in twin configurations.

Flexible Battery Solutions

The HARMO system operates on a 48-volt power supply. Moreover, it offers flexibility in battery choice, supporting dedicated Yamaha lithium-ion batteries or configurations using Yamaha-approved traditional 12-volt batteries. Consequently, boaters can choose the power solution that best fits their needs and budget, along with battery status display (SoC).

Standard Conventional Mounting

The H3.1XSPB is designed with a standard, conventional mounting bracket. This practical design, for instance, ensures ease of installation on a wide variety of transoms and pontoons. Furthermore, it simplifies conversion for existing boats looking to go electric.

Automatic Tilt

The HARMO system features automatic tilt during operation. This means, the motor can automatically tilt up or down as needed. Consequently, it enhances ease of use and helps protect the impeller, especially in varying water depths.

Extremely Low Vibration and Noise

Due to its electric nature and rim-drive design, the H3.1XSPB produces extremely low vibration and noise levels. This makes it ideal for peaceful cruising and quiet fishing, allowing users to fully appreciate the marine environment without distractions.

Environmentally Friendly

As an electric outboard, the H3.1XSPB produces zero water pollution and zero exhaust gas odor. Consequently, it’s an excellent choice for environmentally conscious boaters and for use on waterways with internal combustion engine restrictions.
