Hydro-Shield
Protect your prop
Hydro-Shield is a skeg-mounted hydrofoil that fits on most outboard and inboard/outboard (stern drive) motors, protects your boat’s propeller from underwater impacts, improves your boat’s performance, and shields marine mammals from injury.
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 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. Even if your boat strikes natural hazards like rocks, coral, oyster beds, or sandbars, or man-made hazards like lobster and crab pots, Hydro-Shield maintains its integrity and protects your prop and skeg.
Hydro-Shield is even easy to install as the installation generally takes around 25 minutes for someone who has not installed one before.
Propeller
Guard
Designed to withstand impacts without breaking
Protecting your skeg and prop are essential to avoiding costly repairs down the road and losing time that could be better spent boating. There are no minor skeg and prop accidents. Any chip, scratch, or dent will affect a boat’s handling and require repair.
For every type of debris that can harm your propeller and skeg, Hydro-Shield was made to uphold its integrity, even when you run into often-encountered seafloor debris like…
- Sandbars
- Oyster beds
- Rocks
- Tree stumps
- Lobster and crab pots
Boating in shallow water can also present its challenges in the form of marine wildlife. However, because Hydro-Shield is attached to the bottom of the motor, it protects marine mammals and aquatic grass beds from the danger of propellers.

Large
Fin
Designed for Serious Boating Power
The Large Fin is specifically engineered for substantial watercraft and high-performance motors. This heavy-duty solution is perfectly sized and reinforced to handle the demands of larger vessels and more powerful engines.
Perfect Fit For:
- Boats 18 feet and greater – Ideal for cabin cruisers, fishing boats, pontoons, and other substantial watercraft
- Outboard motors 100hp – 425hp – Handles the power and thrust of high-performance outboards
- Inboard/Outboard (Stern Drive) systems – Compatible with I/O configurations for maximum versatility
Why Size Matters
Larger boats and more powerful engines create greater forces and face bigger challenges on the water. The Large Fin’s robust construction and optimized dimensions provide:
- Enhanced stability for heavier hulls
- Superior protection against the increased debris risk that larger boats encounter
- Improved performance that scales with your boat’s power and size
- Durable construction built to withstand the stresses of high-horsepower operation
Standard
Fin
Engineered for Compact Boating
The Small Fin is precisely designed for smaller watercraft and moderate-power motors. This streamlined solution provides optimal protection and performance enhancement while maintaining the perfect proportions for lighter, more agile boats.
Perfect Fit For:
- Boats 17 feet and smaller – Ideal for fishing boats, skiffs, dinghies, small runabouts, and recreational craft
- Outboard motors 8.9hp – 100hp – Optimized for small to mid-range outboard engines
- Stock bracket configurations – Designed to work seamlessly with standard factory mounting systems
Why Right-Sizing Matters
Smaller boats require a different approach to protection and performance. The Small Fin’s compact design and tailored dimensions provide:
- Proportional protection that doesn’t overwhelm your boat’s design
- Lightweight construction that won’t affect your craft’s agility or speed
- Optimal performance scaled perfectly for smaller hull sizes and moderate power
- Easy installation that works with standard brackets without modifications
