Sea-Dog Line

<p>For over a century, Sea-Dog Line has stood as a cornerstone of the marine hardware industry, delivering innovative solutions that meet the demanding needs of recreational and commercial boaters. Founded in the early 1920s by entrepreneur Hans "Action" Broson Sneve, the company began with a unique sales approach—showcasing marine hardware aboard a 55-foot cruiser that sailed from Alaska to Mexico. This hands-on philosophy continues to shape Sea-Dog's commitment to producing hardware that performs reliably in the harshest saltwater environments.</p><h3>Industry-Leading Marine Hardware Manufacturing</h3><p>Based in Everett, Washington, Sea-Dog Corporation operates a 75,000-square-foot warehouse stocking over 8 million parts and runs an injection molding facility with 16 machines producing more than 17 million components annually. The company's extensive product line spans anchoring systems, deck hardware, electrical components, plumbing fittings, and lighting solutions—all engineered with marine-grade materials like stainless steel, brass, and UV-resistant polymers. Sea-Dog's recognition as a multiple-time NMDA Supplier of the Year underscores the brand's excellence in both product quality and customer service, while their on-staff ABYC-certified marine technician provides invaluable installation and technical support.</p><h3>Premium Marine Components for Every Vessel</h3><p>Sea-Dog's <a href="/7549-sea-dog-line-windshield-washers-wipers-replacement-motors-201195">windshield washers, wipers, and replacement motors</a> deliver crystal-clear visibility during inclement weather, with both manual and electric options featuring corrosion-resistant stainless steel arms and UV-stable blades designed specifically for marine windshield applications.

Product Details

The Sea-Dog Line 502150H1 is a standard lower unit gear oil pump designed for convenient maintenance of marine outboard and sterndrive lower units. This essential tool makes gear oil changes and refills quick and clean, fitting standard quart oil bottles for easy operation.

Key Features:

  • Durable nylon and aluminum construction for long-lasting marine use
  • Standard pump design fits most quart-sized gear oil bottles
  • Flexible hose reaches difficult-to-access drain and fill locations
  • Threaded 3/8"-16 fitting provides universal compatibility
  • Works with Mercruiser, OMC, Evinrude, Johnson, Honda (70hp and up), Volvo, Force, Mercury (US origin models), and Gamefisher lower units

This pump eliminates the mess and hassle of lower unit oil changes by providing precise control over oil flow. The flexible hose extension ensures you can reach tight spaces around the lower unit, while the threaded fitting creates a secure, leak-free connection during filling operations.

Easy to use. But Free Shipping would have been better.
