Product Details

The Davis Instruments 448 Whale Tail XL is an aluminum hydrofoil stabilizer designed to improve boat performance by harnessing wasted propeller wash energy. This innovative device extends behind the propeller to capture and redirect prop wash that would normally be lost, transforming it into usable lift force.

Key Features:

  • Captures and redirects prop wash energy for improved performance
  • Provides immediate throttle response and faster plane times
  • Constructed from durable marine-grade aluminum
  • Mounts directly to the anti-cavitation plate of outboard and stern drive motors
  • Helps reduce bow rise and improve overall boat stability
  • Ideal for ski boats, bass boats, and other high-performance watercraft

The Whale Tail XL design creates lift at the stern when throttle is applied, helping boats get on plane more quickly while reducing fuel consumption. The hydrofoil effect also improves handling in rough water conditions and allows for better weight distribution, making it particularly beneficial for boats operating with heavy loads or uneven passenger distribution.
