Sierra

<p>For nearly six decades, Sierra has established itself as one of the marine industry's most trusted names in aftermarket engine and drive parts. Founded as a specialized marine parts manufacturer, Sierra has grown into a comprehensive supplier of replacement components, instrumentation, and accessories for both recreational and commercial boating applications. Operating from their 300,000-square-foot distribution center in Litchfield, Illinois, Sierra serves boat owners and marine technicians worldwide with an extensive catalog of parts engineered specifically for the harsh saltwater environment.</p><h3>Marine Engine Excellence</h3><p>Sierra's reputation was built on delivering precision-engineered internal engine components and drive system parts that meet or exceed OEM specifications. Their <a href="/7570-sierra-engine-gasket-set-5404">engine gasket sets</a> provide critical sealing solutions for inboard and outboard motors, while their <a href="/7570-sierra-engine-complete-assembly-15341">engine complete assemblies</a> offer comprehensive replacement options for major overhauls. Each component undergoes rigorous testing to ensure reliability in demanding marine conditions, from corrosion resistance to temperature cycling performance.</p><h3>Instrumentation and Monitoring Systems</h3><p>Accurate instrumentation is essential for boat operators to monitor engine health and prevent costly breakdowns on the water. Sierra's comprehensive line of <a href="/7570-sierra-gauges-200483">gauges</a> includes everything from fuel pressure and temperature indicators to voltmeters and trim gauges, all designed with marine-grade materials that withstand vibration, moisture, and UV exposure. Their <a href="/7570-sierra-tachometer-gauge-1488">tachometer gauges</a> deliver precise RPM readings critical for optimizing engine performance and fuel efficiency. Supporting these instruments, Sierra's <a href="/7570-sierra-gauge-resistor-47908">gauge resistors</a> ensure proper signal conditioning and accurate readings across various sensor types and engine configurations.</p><h3>Expanded Product Portfolio</h3><p>In 2022, Sierra significantly broadened its scope beyond traditional marine engine parts to encompass a wider range of boating accessories and even outdoor power equipment components. This strategic expansion brought established marine brands like Shields and Moeller under the Sierra umbrella, creating a one-stop resource for marine maintenance and replacement parts. The company now offers fuel systems, electrical components, battery charging solutions, and NMEA electronics alongside their traditional engine parts lineup.</p><h3>Quality Backed by Industry-Leading Warranties</h3><p>What sets Sierra apart in the crowded aftermarket marine parts market is their commitment to standing behind every component they manufacture. Their warranty coverage extends beyond simple part replacement—it includes shop labor, haul-out fees, towing charges, and related incidental costs should a warrantied part fail. This comprehensive protection reflects the company's confidence in their manufacturing processes and quality control standards. For boat owners facing repairs far from shore or mechanics working on customer vessels, this peace of mind is invaluable. Whether you're maintaining an outboard motor, rebuilding an inboard engine, or upgrading your boat's instrumentation, Sierra's decades of marine industry experience and commitment to quality make them a reliable choice for keeping your vessel running at peak performance.</p>

Product Details

The Sierra 116-128-0386B is a 50-foot length of 3/8-inch split wire conduit designed for marine electrical applications. This flexible protective tubing shields wiring and cables from abrasion, moisture, and environmental damage in harsh marine conditions.

Key Features:

  • Split design allows easy installation over existing wire runs without disconnection
  • 3/8-inch inner diameter accommodates multiple wire bundles
  • 50-foot continuous length minimizes the need for splicing
  • Marine-grade construction resists saltwater, UV exposure, and temperature extremes
  • Flexible material conforms to tight routing paths in engine compartments and bilge areas
  • Protects wiring from chafing against bulkheads, stringers, and hardware

This split loom tubing is ideal for organizing and protecting electrical wiring on boats, personal watercraft, and other marine vessels. The longitudinal split design makes it easy to add or remove wires during maintenance and upgrades without cutting or removing entire wire runs.

Quick and easy. I like!! Thanks!

so far so good

Need it quick as possible please need it for my license. Thanks y'all are the cheapest auto part store around.

It was very easy. The only thing I would suggest is that you include the original part number the item fits. I went by the picture and hope it is the correct part

Great doing bying

Best prices online! Ordered a JBA performance exhaust and Airaid intake system for my 06 F-150. Was hesitant at first because I never heard of them but ordering was a breeze and saved me over $100 total for two items compared to anywhere else. Had package at my door in about 24 hours and even selected normal UPS ground shipping. Very satisfied and will definitely return!

Quick and easy to use website. The part doesn't fit my 2005 Malibu even though the website says it does - have to return the part.
