Hydro Shield Benefits
All benefits of Hydro Shield
Hydro Shield is not just a planing aid. It is one simple solution that affects several parts of how your boat behaves at the same time – from planing time and fuel consumption to propeller protection and comfort in rougher water.
Most boats will notice improvements in several of these areas. The degree of effect depends on the boat, engine, propeller, load, trim and driving style.
Planing and stern lift
Hydro Shield is mounted on the skeg under the propeller and gives the greatest effect when the engine or stern drive is trimmed in/down. This helps the boat get on plane faster, with a smoother and more controlled transition.
- Faster time to plane
- Lower planing speed
- Better stern lift during acceleration
- Less bow rise
- Smoother transition from displacement speed to plane
- Easier to stay on plane at lower speed
- Less need for trim tabs
- Better stability when the boat runs heavy in the stern
Trim, control and handling
Hydro Shield follows the trim angle of the engine or stern drive. This can give better response when you adjust the boat’s running angle according to speed, load and sea conditions.
- More precise trim response
- Easier to trim the boat correctly
- More predictable response from engine and stern drive
- Better control at low and medium speeds
- Better control with heavy load or full fuel tank
- Better control when load and passenger numbers change
- Straighter tracking and more stable course
Available for most outboard motors and stern drives
Turning, manoeuvring and reverse
In harbours, shallow water and narrow areas, good control is important. Hydro Shield can contribute to sharper response and better control – both forward and in reverse.
- Sharper turning forward
- Better control in reverse
- Better manoeuvring in harbours and narrow areas
- Safer manoeuvring in shallow water
Comfort in waves and rougher water
When the boat runs calmer and more controlled, the ride can also feel more comfortable for both driver and passengers.
- Shock-absorbing effect in waves
- Smoother ride in rougher water
- Less bow bouncing
- More comfortable ride for passengers
Fuel, RPM and efficiency
Better planing and more effective trim response can help the engine work more efficiently, especially at low and medium speeds and at normal cruising speed.
- Lower RPM at cruising speed
- More efficient running at low and medium speeds
Protection for propeller, skeg and lower unit
Hydro Shield also works as physical protection around the propeller area. It can reduce the risk of damage from minor bottom contact, shallow water and unexpected obstacles.
- Protects the propeller from minor bottom contact
- Protects the skeg under the propeller
- Protects the lower unit and gear housing from smaller impacts
- Can reduce the risk of propeller damage in shallow or unknown waters
- Gives extra confidence when operating close to shore or in shallow areas
- Can help avoid expensive workshop costs after minor incidents
Ropes, fishing line and shaft seals
Ropes, fishing line and lines in the propeller can cause costly and frustrating damage. Hydro Shield can help guide such obstacles away from the propeller area.
- Reduces the risk of ropes, fishing line and lines entering the propeller
- Can help protect shaft seals from consequential damage
Seabirds and marine mammals
A safety aspect that is not always mentioned, but matters to many boaters operating in shallow water, coastal areas and places with wildlife in the water.
- Can help provide better protection for seabirds and marine mammals near the propeller area
- Can reduce the severity of injury if the propeller area comes into contact with animals in the water
Installation and application
Hydro Shield is designed to fit a wide range of boats and is mounted on the skeg under the propeller. It is not mounted on the cavitation plate.
- Fits both outboard motors and stern drives
- Can be used on boats with one or several engines
- Mounted on the skeg under the propeller
- Installed with 3 bolts
- Wing made from special plastic/composite
- Stainless steel brackets and fasteners
One solution – many benefits
What makes Hydro Shield different is that it combines performance, control, comfort and protection in one compact solution.
- Provides both performance benefits and physical propeller protection in one product
- Combines planing, control, comfort, fuel efficiency and protection
- Helps most during acceleration, heavy load, lower speeds and manoeuvring close to shore
- The effect is greatest when the engine or stern drive is trimmed in, and more neutral when the boat is on plane and the engine is trimmed out
Find the right model for your boat
Hydro Shield is available in several models for different engines, stern drives and skeg sizes. Visit the product page to find the model that fits your setup.
