Manufacturer

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>

Been good although I never got a response about the wrong gaskets in my last order.

Found your site in a sidebar to Ebay listing. Better price, exact same product - Thanks!

fast secure variety

Finding the part, and ordering it was great. But UPS dropped the otherwise phenomenal ball... Ordered the item on Wednesday... got it the next MONDAY. I ordered it Second Day Air. Then I find out, &quot;Oh, it's Second BUSINESS Day Air... we don't work on weekends.&quot; Well, it was a critical auto part, that's why I ordered it Second Day Air... but they were unconcerned. If I were to order from here again it would only be if I could choose some other option of delivery, like USPS... they actually DO deliver on the weekends.

Easy

very easy/friendly website

Good so far

I'm a stickler for finding the best prices on my purchases, while also making sure that the products I buy are legit and not some cheapo knock-offs.<br>I did my homework on the Clutch Stage 2 kit I wanted for my Spec V and found that Autoplicity had the best price anywhere, even a spot where I had 10% off came out to be more expensive.<br><br>I received my Clutch Stage 2 clutch kit pretty quickly (about 1 week) and everything was as expected.<br><br>Overall I would rate Autoplicity a perfect 10, although I did not have to contact their customer service or initiate a return, so the '10' would be on product selection, communication, website experience, and overall feeling that I got the best deal out there.<br><br>Thanks!

Great pricing; easy to order.

Parts arrived in a timely fashion. Packing could have been better but product arrived safely.

Excellent service and the cheapest price that I could find anywhere. Ordered on a Sunday and delivered in record time three days later...basic overground shipping. I will deffinately order from here again!
