Monoblock Propellers

We specialize in developing custom fixed pitch propellers and have been supplying them for over 20 years. Our customers are looking for unique solutions where silence, speed and minimal vibrations are the highest priority. We listen closely to our customers’ needs and machine to their exact specifications. Dominis consistently exceeds ISO 484 Class “S” tolerances, making our propellers ideal for navy, coast guard and super yacht vessels.

At Dominis, we manufacture monoblock fixed pitch propellers up to 2 meters in diameter. To eliminate hand grinding, all propeller blade surfaces are CNC milled to final form and finish. By eliminating hand grinding, the end result is identical propeller blades without any fluctuations. This precision means our propellers have minimal vibrations and noise while delivering excellent fuel efficiency and durability.
