Extreme 2-1 OP/WT w/3in Tach

The Extreme 2-1 OP/WT w/3in Tach is a professional-grade gauge panel assembly built for serious boaters and performance marine engine builders who demand real-time diagnostics at the helm. This three-in-one instrument cluster combines oil pressure, water temperature, and tachometer monitoring into one compact, white-faced dashboard unit—eliminating the need for multiple separate gauges and delivering the clean, integrated cockpit layout that competitive and recreational powerboat operators rely on. Whether you're pushing a high-performance engine or managing a dependable cruiser, unified instrument monitoring ensures you catch critical engine conditions before they become costly problems.

This assembly features a dual-diameter design with a 3-3/8 inch tachometer and 2-5/8 inch auxiliary gauges, engineered by QuickCar Racing Products to withstand the vibration, temperature swings, and electrical noise inherent in marine engine compartments. The integrated tachometer includes recall function—a critical feature that captures and holds peak RPM readings so operators can verify maximum engine performance during acceleration runs or diagnostic testing. White-faced dial design delivers superior readability in varied light conditions, from pre-dawn runs to full midday sun, while the kit configuration includes all necessary wiring, sender connections, and mounting hardware for straightforward integration into existing or custom dashboard installations.

This gauge panel is ideal for custom boat builders, marine mechanics, performance engine shops, and hands-on owners upgrading aging or inadequate stock instrumentation. The compact footprint—measuring 10.6 x 6.95 x 16.35 inches and weighing just 3.66 lbs—fits retrofit applications and new builds alike without dominating console or dash real estate. Installation pairs best with compatible marine sender units and 12-volt DC electrical systems common to inboard and outboard powerboats; verify sender compatibility with your engine's oil pressure and coolant temperature ports before final purchase.
