Hydro Shield will get your boat on plane faster, allowing you to remain on plane at lower speeds and rpm's. It also improves handling and lowers your fuel burn at low and cruising RPM settings. Hydro-Shield will also protect your propeller from damage due to underwater impacts, and its 316th's marine grade stainless steel bracket system acts as a skeg guard, strengthening and reinforcing the skeg.

Made from an energy-absorbing plastic compound, Hydro Shield can withstand impacts, natural or man-made.

Hydro Shield is even easy to install. Installation is a two-step process that only requires four bolts and lock nuts. It can be completed in minutes, without messy glue or professional-grade welding.
