ERMA FIRST FLEXCAP
View More
ERMA FIRST FLEXCAP helps to reduce the formation of hub vortex, which can reduce the propeller’s efficiency and cause cavitation and noise. The fins cancel out the vortices generated at the root of each blade, reducing the torque demanded for the same RPM and can occasionally generate additional thrust.
-
Diameter: Approximately 23%-25% of the propeller diameter
-
Weight: Roughly 3% of the propeller weight (no need for shaft alignment recalculation)
-
Material: ERMA FIRST FLEXCAP is made from NiAlBronze, the same material as the propeller, ensuring durability and longevity
*The dimensions and weight may vary based on specific design but are not expected to increase significantly
ERMA FIRST FLEXRING
View More
The ring guides the flow towards the propeller in a way that it increases the speed at the areas of obstructed flow and improves propulsive efficiency. Additionally, there is some thrust that develops on the duct and with proper alignment of the fins (optional) a pre swirl effect is created, increasing further the efficiency of the propeller.
– Easy-to-assemble parts and quick installation
– Case-specific adjustments
ERMA FIRST FLEXFINS

A set of fins properly placed and aligned, guide the flow around the hull in a way that it is more evenly distributed, reducing resistance, and assisting in directing better flow to the propeller.
– Minimal intervention to the hull
– Same day installation
