This combination of design and manufacturing strengths results in a propeller series second to none!
New PropellersPrecision machining of new propellers assures proper fit in final assembly. We can build to customer provided designs, we can provide our own standard designs or we can provide a custom design according to the performance needs of your vessel. We can recommend the most efficient propeller for your vessel based on our experience. We take into consideration the power and rpm, the work the vessel will be doing, the area in which the vessel will be working and the design of the vessel. This will help us provide you with propellers which will provide optimum performance. We make the patterns for new propellers at Sound Propeller’s on site Pattern Shop, and then utilize the services of Atlas Chehalis, Atlas Tacoma, or Meltec Foundries. The metal content specifications unique to Sound Propeller are stringently adhered to by the professionals at these foundries. We use only the finest, time proven materials, either stainless steel or special bronze alloys. Our stainless steel alloy provides strength, corrosion resistance, reparability, and ductility, and exceeds all ABS physical requirements. We use computer assisted design analysis to aid in the selection of the blade shape, thickness and type of material for your vessel's particular use. Our large pitch table enables us to pitch, straighten and track propellers up to 13 feet in diameter.
