<h3>Sierra: Six Decades of Marine Aftermarket Excellence</h3><p><strong>Sierra</strong> has spent nearly 60 years earning its reputation as one of the most trusted names in the marine aftermarket industry. Originally focused on engine and drive components for boats, the brand has grown into a comprehensive source for nearly everything a boater needs to keep their vessel running at its best — from precision instrumentation to complete engine rebuild hardware.</p><p>Now operating as a brand of Dometic, Sierra manages global aftermarket distribution from a 300,000 sq. ft. facility in Litchfield, Illinois. The Sierra brand today encompasses not only its flagship marine parts line but also well-established marine names like Shields and Moeller, offering boaters a broader catalog than ever before. Whether you own an outboard, inboard, or sterndrive, Sierra's engineering team designs products to meet or exceed OEM specifications.</p><h3>Precision Instrumentation You Can Trust on the Water</h3><p>One of Sierra's most recognized product areas is its marine instrumentation lineup. The brand's <a href="/7570-sierra-gauge-set-1480">gauge sets</a> cover everything from classic analog instrument clusters to advanced digital multi-function displays. Sierra offers packages suited to outboards, sterndrives, and gasoline-powered inboards, with options ranging from coordinated analog kits in styles like Arctic, Eclipse, and Amega to modern touchscreen solutions like the R3 multi-function gauge. Features such as scratch-resistant domed glass lenses, silicone-dampened pointers, and perimeter backlighting make these instruments highly readable in all conditions.</p><p>Behind every accurate gauge reading is a properly calibrated sending circuit. Sierra's <a href="/7570-sierra-gauge-resistor-47908">gauge resistors</a> are a critical part of that chain, ensuring the signals from sensors and sending units are correctly interpreted by your instruments. These components are built to marine-grade standards to resist moisture, vibration, and corrosion — the realities of life on the water.</p><h3>Engine Internals Built to OEM Standards</h3><p>Sierra's history in marine power is perhaps best demonstrated by its deep catalog of engine components. The brand's <a href="/7570-sierra-engine-gasket-set-5404">engine gasket sets</a> cover a wide range of outboard and inboard applications and are engineered to deliver reliable seals in the demanding thermal and chemical environment of a marine engine. For boaters performing seasonal overhauls, top-end rebuilds, or full engine restorations, Sierra gasket kits are a go-to resource trusted by professional marine technicians and DIY boaters alike.</p><h3>A Complete Marine Parts Partner</h3><p>Beyond instrumentation and engine internals, Sierra's catalog spans fuel systems, electrical supplies, steering components, shore power, and more — all covered by what the brand calls an industry-leading warranty. Sierra also maintains a comprehensive parts-finder tool that enables cross-referencing with OEM part numbers from major manufacturers including Mercury, Yamaha, Suzuki, Volvo Penta, and others, making it straightforward to find the right replacement part for virtually any application.</p>

Product Details

The Sierra 18-9788 is a professional-grade gear lube pump designed to mount directly onto 5-gallon (35 lb) open-head pails for efficient filling of outboard and stern drive lower units. This pump delivers extremely high volume per stroke, transferring gear oil directly from the pail to the lower unit with ease.

Key Features:

  • Mounts directly to 5-gallon open-head pails for convenient gear oil dispensing
  • High-volume delivery per stroke for faster lower unit filling
  • Includes 5-foot clear vinyl hose with adapter for easy connections
  • Features threaded lube fitting to thread directly into domestic lower units
  • Tapered/unthreaded hose end provides versatile connection options
  • Compatible with Sierra 5-gallon gear lube buckets (18-9600-5, 18-9620-5, 18-9650-5, 18-9680-5)

This marine maintenance tool simplifies the process of servicing outboard motors and stern drives, eliminating the mess and hassle of traditional gear oil filling methods. The transparent hose allows you to monitor oil flow during the filling process.

Once I got the numbers off the old battery it was easier than when I put in the make and model because I have a BMW motorcycle instead of the car which is what came up each time.

So far so good, best price I could find that actually had the part in stock

I did my homework on what fuel pump to buy, and even more homework on who to buy it from. Autoplicity had the best price including shipping of everythere I looked, and were quick to answer the phone confirming they indeed had the part in stock to ship. It was sent within 24 hours of placing the order.<br><br>I'd definitely buy from them again.

Simple. Great service!

So far so good thank you

I had a smog guy call me out that my filter was ok, my truck passed but since my pipe wasn't name brand we wouldn't pass me. It's a 2008 Nissan Titan. Needless to say I wasn't to happy about it but this place had what I needed for about $50 less than anywhere else and it shipped within 2 days. So far, so good, thanks Autoplicity

easy to pay through Amazon

Quick.

fast and easy ordering process.

Autoplicity had great communication, good prices, and got the item in the mail quickly. Would definitely order through them again.

Best price for a product I've been shopping for, for months, and when I saw Autoplicity having it for A LOT cheaper, putting the product in my sweet spot price wise, I didn't hesitate to order. <br><br>My bank was a little slow to post the transaction, and I was suprised to get a human on the phone with no effort to make sure my order was properly processed. The gentleman I spoke with was very friendly and promptly answered all my questions. <br><br>Only the $5 I'm getting back for this review can make this deal any better, as I have no suggestion for improving the transaction I made with them.

Found part quickly. Price was competitive.
