In the selection of power upgrades for small boats, electric outboard motors are gradually replacing traditional fuel models due to their advantages of environmental protection and low noise. As a mainstream 1.5kW-class electric outboard motor, the Fuber G1.5 is often asked by anglers and leisure boat enthusiasts: Is the noise loud? Is the vibration obvious? This article comprehensively answers these two core questions from three aspects: technical principle, measured data and scenario experience.

1. Noise Performance: Far Lower Than Fuel Engines, Close to Daily Conversation Volume

1. Core Noise Sources & Measured Values

The Fuber G1.5 adopts a brushless DC motor + shaftless direct drive architecture, completely abandoning the internal combustion combustion and piston friction structure of fuel engines. Its noise only comes from propeller water cutting and low-frequency electromagnetic vibration of the motor.

Measured Noise Level: No-load / cruising (50% speed) is about 52-58 decibels; full-load full speed (1200rpm) is about 58-62 decibels, equivalent to the volume of daily face-to-face conversation (around 60 decibels).

Comparison with Fuel Engines: The noise of fuel outboard motors of the same power reaches 80-100 decibels, similar to car horn roar. The G1.5 reduces noise by about 30%, and almost no obvious sound can be heard 10 meters away.

2. Low Noise Technical Advantages

Shaftless Direct Drive Design: The motor is directly coupled with the propeller, without mechanical transmission parts such as gears and drive shafts, reducing transmission friction noise.

Low-frequency Noise Reduction Optimization: The motor operating frequency is concentrated in the low-frequency band, which attenuates rapidly when propagating in water. The noise at 10 meters underwater is only 1/4 of traditional shafted models, will not scare fish schools and disturb the water ecological environment.

3. Actual Scenario Experience

Fishing Scenarios: Silent navigation will not scare away fish schools, allowing you to approach fishing spots closely and increase catch rate.

Leisure Sightseeing: When sailing on lakes and inland rivers, there is no roar interference, allowing you to clearly feel the tranquility of the water and natural sounds.

Night / Silent Waters: It meets the low noise requirements of scenic spots and ecological reserves, with no worries about noise pollution.

2. Vibration Performance: Almost Imperceptible, Much Better Than Fuel Engines

1. Core Advantages of Vibration Control

The vibration control of Fuber G1.5 stems from the inherent advantages of electric power and structural optimization:

No reciprocating vibration of internal combustion engine: Piston reciprocating motion and cylinder combustion of fuel engines produce high-intensity strong vibration, while the motor of G1.5 runs in uniform rotating motion without reciprocating impact, greatly reducing vibration sources.

Lightweight + Rigid Structure: The net weight of the whole machine is only 16kg (excluding battery). The fuselage is made of high-strength aluminum alloy with compact structure and high rigidity, avoiding resonance during operation.

Suspension Buffer Design: Shock-absorbing pads are equipped at the stern mounting position to further weaken the transmission of slight vibration to the hull and improve navigation stability.

2. Actual Vibration Sensation

Handheld / Stern Perception: Almost no obvious vibration at idling and cruising speed; only slight low-frequency vibration can be felt when touching the fuselage. Even at full speed, the vibration amplitude is far lower than fuel engines, without hull jitter or handrail numbness.

Hull Impact: Suitable for 3-6m small fishing boats, kayaks and sailboats. The hull runs smoothly without the jitter sense of fuel engines, making standing and sitting more comfortable for passengers.

3. Comparison with Traditional Models

Fuel outboard motors of the same power produce obvious hull vibration, which easily causes fatigue after long-time riding; while the Fuber G1.5 achieves an almost "imperceptible" vibration level, bringing no discomfort even after long-time navigation, especially suitable for leisure fishing, short-distance cruising and other long-time usage scenarios.

3. Core Technical Summary: Why It Achieves Low Noise & Low Vibration

Power Architecture Innovation: Brushless motor replaces internal combustion engine, eliminating combustion noise and reciprocating vibration, reducing noise and vibration fundamentally.

Shaftless Direct Drive Technology: Reduces transmission parts such as gears and drive shafts, avoiding transmission friction noise and clearance vibration.

Precision Process Optimization: Dynamic balance calibration for motor stator and rotor; propeller adopts CFD simulation optimized design for smoother operation and reduced water impact vibration.

Scenario-adaptive Calibration: Optimize motor speed range and power output curve for small boat usage scenarios, balancing power, silence and stability.

4. Conclusion: Low Noise & Low Vibration, The Preferred Comfort Power for Small Boats

Based on actual measurement and technical analysis, the Fuber G1.5 electric outboard motor features low noise and weak vibration: the noise is controlled at about 60 decibels, close to daily conversation; the vibration is almost imperceptible, far better than same-class fuel outboard motors.

Whether anglers pursue "silence without scaring fish" or leisure players value "comfortable navigation without noise", the Fuber G1.5 is perfectly compatible. It is an optimal choice for environmental-friendly, quiet and stable power upgrade for 3-6m small boats.
