Propellers with M2 Thread – Precise Fit for Model Boats

In the Propellers with M2 Thread category at Ship Models Shop, you’ll find brass and plastic propellers designed for small to medium model boats. They deliver reliable thrust, low cavitation, and a precise M2 fit for clean, secure installation.

Why choose M2 thread propellers

• Fine, precise threading for compact hulls and lightweight drivetrains

• Application-ready options for tugs, motor yachts, steamers, and classic craft

• Rotation choice: right-hand as standard; left-hand versions on selected sizes

• Material flexibility: brass for durability, plastic for lightweight builds

Technical options

• Blade types

  • 2-blade: low drag and high efficiency for sailboats and small steamers

  • 3-blade: added thrust and smoother running for working boats and cruisers

• Materials

  • Brass: robust, scale-accurate look, long service life

  • Plastic (often glass-fiber reinforced): light, budget-friendly, versatile

• Sizes

  • Multiple diameters and pitches to match hull size and motor power

Buying guide – how to pick the right M2 propeller

1. Model type: light sailers/steamers → 2-blade; working or heavier boats → 3-blade

2. Material: brass for durability and scale detail; plastic for weight-sensitive builds

3. Diameter & pitch: tune to motor KV and desired speed/torque balance

4. Rotation: standard right-hand; left-hand where twin-shaft or setup demands it

Conclusion

M2 thread propellers offer a clean, reliable interface for small model boats. Choose from brass or plastic, 2- or 3-blade, and a range of diameters and pitches to optimize thrust, efficiency, and scale appearance.
