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.

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 OP24891 is a marine-grade oil pressure sender designed for dual station gauge systems, allowing oil pressure monitoring from two separate locations. This sender provides accurate pressure readings up to 80 PSI, making it suitable for most inboard and sterndrive marine engines.

Key Features:

  • 80 PSI maximum pressure rating for reliable oil pressure monitoring
  • Dual station capability allows connection of two gauges simultaneously
  • 1/8"-27 NPT thread for standard engine block installation
  • 10-32 stud terminal for secure electrical connections
  • Corrosion-resistant construction for harsh marine environments
  • Compatible with standard analog oil pressure gauges

This sender unit threads directly into the engine block's oil pressure port and converts mechanical oil pressure into an electrical signal that drives your gauge(s). The dual terminal design eliminates the need for splicing wires when running gauges at both helm and engine room locations. Ideal for replacement or new installations on most marine gasoline and diesel engines.

Placed order #27494 for some bumpstops. Came out $40 cheaper then i could get with reseller discounts elsewhere. Great item, shipped quick, very satisfied.

The product came at the very last minute. So we had to do something different plus the &quot;return&quot; directions on the website were not clear, i.e. the return process is not easily executed.
