Sound Propeller Systems was established April 2007. The company was formed to extend the parent companies ability to provide specialized technical services in repairs of marine propulsion systems including controllable pitch propellers, bow thrusters, electronic and pneumatic control systems and sterntube sealing systems. We are presently expanding our business designing a range of z-drives from 1500 to 3500 horsepower.

We will extend our manufacturing line to include controllable pitch propellers and bow thrusters as time and or demand dictates.

Our goal is to design a robust machine that is manufactured in the United States with ISO 9001 subcontracted parts and assembled under our control and overseen by ABS to achieve a Type classification. We are determined to produce a modular package that is user friendly, factory supported with spare parts and trained service technicians to assist when necessary.

Our company’s experience is based on four owners with an excess of 100 years of work related to the design, installation and testing of propulsion systems including shafting, fixed pitched propellers, controllable pitch propeller systems, bow thrusters and sterntube seals world wide.

Our staff includes both mechanical and electrical competent employees. We are a hands on group that understands the needs of the marine industry.
