StingRay StarFire Hydrofoil No/Optional Drill - Black 40-300 HP

The StingRay StarFire is engineered to maximize top ~end speed by inverting its trailing edge to reduce drag and extending its wing tips to enhance stabilization while on plane.
Fits Most Outboards and Sterndrives
Engines 40 ~300HP
Moderate lift

Features
Gets boats on plane quicker
Keeps boats on plane at lower speeds
Improves stabilisation
Saves fuel
Increases visibility at lower speeds
Reduces chine walking, porpoising, cavitation, and ventilation.
Recommended for all types of boats.

The Starfire features No Drill or 2 Drill & Bolt installation
Two Drill & Bolt Installation
Slide the unit onto the cavity plate and drill & bolt in place.
No Drill Installation
This can be accomplished in two ways. The one ~piece hydrofoil slides onto the cavitation plate and screws set within the unit engage the edge of the plate. Alternatively, the hydrofoil can be held in place by removing and refixing the anode or torque tab with the unit inserted between.
How it works
Hydrofoils work by utilizing the principles of fluid dynamics to generate lift and reduce drag. They consist of a wing ~like structure called a foil fixed to the outboard cavitation plate or sterndrive which is submerged underwater. As water flows over the foil, it generates lift, allowing the hydrofoil to rise, levelling the boat, getting it on plane and gliding it smoothly through the water.
