Sierra

<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 18-7695 Fuel Injector Seal Kit is a precision-engineered marine replacement seal kit designed for MerCruiser GM Multi-Port Injection (MPI) engines. This kit provides the seals needed to properly reseal fuel injectors, helping to prevent fuel leaks and maintain correct fuel delivery in your marine engine.

Sierra International manufactures this kit to meet or exceed OEM specifications, making it a reliable aftermarket alternative to Mercury OEM part numbers 25-892609 and 885176. Each kit contains two seals for one injector and is compatible with Mercury Injector #885176.

Key Features:

  • Direct replacement for OEM part numbers: 25-892609, 885176
  • Cross-references: Sierra 18-7688, Walker 9-33101
  • Contains 2 seals per kit (sufficient for one injector)
  • Designed specifically for marine MPI fuel injection systems
  • Manufactured to meet or exceed OEM fit, form, and function
  • Compatible with MerCruiser ECM 555-equipped engines (2002 and newer)

This seal kit is the correct choice for MerCruiser 4.3L, 5.0L, 5.7L, and 6.2L MPI sterndrive and inboard engines equipped with the ECM 555 engine management system. Replacing worn or damaged injector seals helps restore proper fuel system integrity and prevents potential hard-start, rough-idle, or fuel odor issues.
