Solas

<h3>About Solas Science &amp; Engineering</h3><p><strong>Solas Science &amp; Engineering Co., Ltd.</strong> has been a defining force in marine propulsion since its founding in 1985 by Dr. Solas Y.J. Lin. Headquartered in Taichung, Taiwan, the company has grown from a focused propeller manufacturer into one of the most recognized names in the global marine industry. Today, Solas is widely regarded as a world leader in the design and manufacture of propellers for outboard and stern drive engines, as well as impellers and pump systems for personal watercraft (PWC) and jet boats.</p><p>What sets Solas apart is a relentless commitment to engineering quality at every stage of production. Solas propellers are crafted using two distinct advanced processes: investment casting for stainless steel models and squeeze casting for aluminum models — techniques that deliver superior material density, corrosion resistance, and blade precision. Solas aluminum propellers also feature multiple paint layers for enhanced anti-corrosion protection, far exceeding industry-standard finishing. Stainless steel models are formulated with high levels of molybdenum, nickel, and chrome for exceptional hardness and durability in harsh saltwater environments.</p><h3>Engineering Excellence Across Every Product Line</h3><p>Solas operates a fully integrated research and development facility in Taiwan, employing CAD, CAM, and CAE technologies to continuously refine its product designs. Every propeller and impeller goes through extensive testing — including salt fog testing and simulated field use — before entering mass production. This dedication to verifiable quality is why marine technicians and boating enthusiasts around the world consistently turn to Solas when performance and reliability matter most.</p><p>Beyond boat propellers, Solas has developed a comprehensive lineup of <a href="/5584-solas-impellers-200573">PWC impellers</a> sold under well-known series names such as the Concord, Dynafly, X-Prop, and Super Camber. These impellers are engineered to boost thrust, reduce cavitation, and improve acceleration for Sea-Doo, Yamaha, Kawasaki, and other popular watercraft platforms. Complementing these are complete <a href="/5584-solas-engine-cooling-pumps-accessories-200368">engine cooling pumps and accessories</a> — including full jet pump assemblies — developed using modern hydrodynamics principles and tested by Solas&apos;s own PWC racing team.</p><p>For boaters who want to fine-tune their setup, Solas also offers an extensive selection of <a href="/5584-solas-propeller-parts-accessories-200817">propeller parts and accessories</a>, from hardware kits to interchangeable hub systems, making it easy to adapt props to different engines or service an existing prop without replacing the entire unit.</p><h3>Why Boaters Trust Solas</h3><ul style="list-style:disc"><li>Decades of marine engineering expertise founded on precision manufacturing</li><li>Wide range of stainless steel and aluminum propeller options for outboard and stern drive engines</li><li>Purpose-built PWC impeller series for leading watercraft brands including Sea-Doo, Yamaha, and Kawasaki</li><li>Advanced casting technologies for superior material integrity and corrosion resistance</li><li>Comprehensive propeller accessories that simplify maintenance and hub customization</li><li>Rigorous quality controls including real-world field testing and salt fog exposure trials</li></ul><p>Whether you&apos;re replacing a worn-out prop on a fishing boat, looking to extract more speed from your jet ski, or rebuilding a cooling system component, Solas delivers the engineering depth and product breadth to get the job done right.</p>

Featuring a right-hand rotation with 14-inch diameter and 21-inch pitch, this 3-blade design delivers excellent acceleration and efficient cruising performance across a wide RPM range.

Key Features:

  • Premium stainless steel construction for durability and corrosion resistance
  • Interchangeable hub system for easy installation and hub replacement
  • Large ear blade design optimizes water flow and reduces ventilation
  • 3-blade configuration balances acceleration with top-end speed
