StringRay XRIII Hydrofoil

The StingRay XRIII is designed with a new sleeker hydrodynamic profile for the fastest hole shot yet.

This unique design mirrors the tunnel-prop technology of offshore superboats. By capturing the prop wash, the XRIII harnesses its power for added thrust.

A unique coating process, Speed XP, bonds to the base material of the StingRay® XRII Hydrofoil Stabilizer™. Acts like a microscopic sponge when wet and binds a thin layer of water to the surface, creating a dramatic reduction in hydrodynamic drag, greatly improving performance.

You'll enjoy better performance and greater fuel savings. The XRIII also utilizes a vice-block 3-point locking system for easy no-drill installation. Installs in about five minutes with only a socket wrench and a Phillips screwdriver. No more measuring. No more templates. No more damage to your engine. For engines up to 300 hp.

NO-Drill Installation Hydrofoils were pioneered and patented by StingRay. The goal is to create hydrofoils that could be installed without holes being drilled into the engine. The No-Drill Installation method differs depending on which StingRay Hydrofoil model you choose, but each method requires zero drilling and allows for installation in under 10 minutes.
