How to Choose Thrusters of Different Thrust Levels? A Detailed Comparison of 7 KG, 39 KG, and 86 KG Thrust Options

Postado por Fengyukun em 5 de dezembro de 2025

Why is thrust selection important?

Higher thrust doesn't necessarily mean better performance.
Appropriate thrust should be matched to the ship's weight, speed requirements, operating environment, and battery capacity.

Too little thrust → "Slow to move, drifts in wind, difficult against currents"
Too much thrust → "High power consumption, short range, difficult to control, wasteful costs"

Choosing the right thrust is choosing the balance between power and efficiency.

1.How to quickly estimate thrust requirements?

Empirical guidelines:

Smooth cruising: 25–30 kg boat weight ≈ 1 kg thrust

Upstream, high speed: 20 kg boat weight ≈ 1 kg thrust

Examples:

150 kg kayak → 5–8 kg thrust

300 kg small boat → 10–15 kg thrust

600 kg workboat → 25–35 kg thrust

1000 kg go-kart → 60–100 kg thrust

This helps you determine which type of thruster is best suited to your needs.

2. Selection based on application scenario – Comparison of APISQUEEN thruster series

Note: The higher the thruster power, the heavier the battery and ESC components will be.

Please ensure your power system can safely handle the required current.

Except for the U5 underwater thruster, which is a freshwater thruster, all other models are designed for marine environments. If your application involves prolonged exposure or heavy marine use, the U35 underwater thruster and BP150 pump Jet Thruster, with their anodized aluminum and stainless steel construction, offer enhanced corrosion resistance.
