The four-stroke air-cooled stern motor has the following advantages:
-
No need for a water cooling system: Eliminates water-cooling components such as water tanks, water pumps, and water pipes, resulting in a simpler structure, lighter weight, and lower installation and maintenance costs. It is particularly suitable for small boats or scenarios requiring lightweight designs.
-
Convenient maintenance: The air-cooled system avoids risks of water leakage and scaling, and there is no need for regular coolant replacement, making daily maintenance more hassle-free. It is ideal for use in waters with complex water quality or in water-scarce environments.
-
Strong environmental adaptability: Unaffected by water temperature, it can operate stably in low-temperature waters or waters with turbid water quality, avoiding malfunctions of water-cooled systems caused by excessively low water temperatures or blockages from impurities.
-
Stable heat dissipation efficiency: Forced heat dissipation through fan or airflow design ensures that the heat dissipation effect is less affected by working conditions. It is suitable for long-term high-speed operation with high reliability.
-
Stable power output: The four-stroke engine features a smoother working cycle and uniform torque output, leading to more stable boat speed during navigation and better maneuverability. It is suitable for carrying passengers, transportation, or leisure cruising.
-
Excellent fuel economy: The four-stroke engine achieves more complete fuel combustion, resulting in lower fuel consumption compared to two-stroke models, reducing operating costs. Additionally, it has more environmentally friendly emissions, meeting modern environmental protection requirements.
-
Low noise and vibration: With a more precise structural design, it produces lower noise and vibration during operation, enhancing passenger comfort. It is especially suitable for scenarios such as leisure fishing and sightseeing.
-
Small boats: Such as fishing boats, yachts, and speedboats. Its lightweight and easy-to-maintain characteristics meet the needs of short-distance operations or entertainment.
-
Complex waters: In shoals, inland rivers, or areas with poor water quality, there is no need to worry about the water cooling system sucking in impurities, making it more convenient to use.
