The 4519 Stainless Steel Propeller is a high-performance upgrade for the ProBoat Sonicwake 36 (V1 and V2).
Made from strong, high-grade stainless steel using CNC machining, this prop delivers exceptional rigidity, precise geometry, and stable operation at high RPM.

The optimized blade profile provides excellent water bite, sharp acceleration, and clean power delivery without cavitation or loss of traction.

🔥 Key Advantages:

• Stronger hole-shot acceleration — the boat reaches speed faster and more confidently

• Higher top speed compared to stock plastic or cast propellers

• Perfectly straight tracking
  ➝ the reactive torque does not roll the boat or pull it to the side

• Stable behavior during aggressive throttle inputs and in choppy water

• Reduced cavitation even under sudden, full-power starts

• Extreme durability — stainless steel resists impacts, sand, debris, and harsh use

• Fully suitable for high-power brushless setups and performance builds

Each propeller is CNC-machined, professionally dynamically balanced, and hand-finished to ensure smooth, consistent, and reliable operation at high speeds.

✔ Compatibility:

• ProBoat Sonicwake 36 V1

• ProBoat Sonicwake 36 V2

This propeller is an excellent choice for speed enthusiasts and one of the best options for competitive oval group racing, where stability, clean tracking, and strong acceleration are crucial.
