<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>

Product Details

The Solas 81051151 is a precision-engineered washer spacer designed specifically for Mercury outboard motors with E-Series lower units. This essential propeller hardware component ensures proper spacing and alignment between the propeller and the propeller shaft, maintaining optimal performance and preventing premature wear.

Key Features:

  • Mercury-specific washer spacer for E-Series applications
  • Manufactured by Solas to OEM specifications for precise fit
  • Corrosion-resistant construction for marine environments
  • Essential component for proper propeller installation and retention
  • Type M spacer configuration for specific Mercury models

This spacer is a critical part of the propeller installation system, working in conjunction with the propeller nut and thrust washer to secure the propeller safely to the shaft. Proper spacing ensures correct propeller positioning and prevents hub slippage during operation.

Note: Spacer type and configuration may vary by specific engine model and year. Always verify compatibility with your Mercury outboard motor before installation.
