Davis Whale Tail XL Aluminum Stabilizer Ski Boat Fin

The Whale Tail XL converts prop wash energy into lift behind your boat, delivering immediate throttle response and enhanced stability for I/O and outboard-powered craft.

Its hydrodynamic design captures energy normally lost in the prop wash, reducing porpoising, smoothing rough-water rides, and flattening the wake for easier water skiing. Lowering the bow also improves visibility and safety during navigation.

• Hydrodynamic design captures prop wash energy to generate lift for improved response
• Stabilizes bow-light boats during high-speed operation
• Flattens wake for easier water skiing and creates positive, skid-free turns
• Reduces porpoising and cavitation for a smoother ride
• Increases top speed and fuel efficiency in many applications
• Universal mounting on the anti-cavitation plate of most inboard, outboard, and outdrive motors
• Easy installation in about 15 minutes with included stainless steel hardware
• Marine-grade aluminum with a durable anodized finish for saltwater and freshwater durability
• Year-round use in freshwater or saltwater environments

Constructed to withstand harsh marine conditions, the Whale Tail XL is a reliable upgrade for improving handling, safety, and performance across a wide range of boats and operating styles.

Whale Tail XL

Aluminum Stabilizer and Ski Boat Fin

Improves performance in any I/O or outboard motor!

The Whale Tail XL extends out behind the prop to utilize prop wash energy which is normally lost. Whale Tail transforms this energy into lift for immediate response when the throttle is applied.

• Unique hydrodynamic design
  
• Stabilizes bow-light boats
  
• Pops skiers up in less time

Flattens wake for water skiing; creates positive, skid-free turns:

• With bow lowered, visibility and safety is improved
  
• Smooths out ride in rough water
  
• Reduces porpoising & cavitating
  
• Increases top speed and fuel savings in most applications
  
• Mounts on the anti-cavitation plate of all inboard/outboards and outboards
  
• Installs in 15 minutes with stainless steel hardware included
  
• Marine grade aluminum with durable anodized finish
  
• Use the Whale Tail XL year-round in freshwater or saltwater to improve performance of any boat!

The Davis Instruments Whale Tail XL is a high-performance aluminum stabilizer designed to enhance the handling and efficiency of any I/O or outboard motor-powered boat. Its unique hydrodynamic design captures prop wash energy that is typically lost, converting it into lift that provides immediate response when the throttle is engaged. This feature results in quicker acceleration, improved stability, and better overall boat performance. Crafted from marine-grade aluminum with a durable anodized finish, the Whale Tail XL is built to withstand harsh saltwater and freshwater conditions, ensuring long-lasting reliability. Installation is straightforward, taking approximately 15 minutes using the included stainless steel hardware, and it mounts easily on the anti-cavitation plate of most inboard, outboard, and outdrive engines. Its versatile design makes it suitable for year-round use, helping boaters achieve optimal performance in various water conditions.
