Extreme 4-1 OP/WT/OT/FP w/ 5in Tach

The Extreme 4-1 OP/WT/OT/FP with 5in Tach from QUICKCAR RACING PRODUCTS is a professional-grade multi-function marine gauge built for serious anglers, boaters, and performance enthusiasts who demand real-time monitoring on the water. This instrument consolidates four critical engine parameters—oil pressure (OP), water temperature (WT), oil temperature (OT), and fuel pressure (FP)—into a single compact display, eliminating dashboard clutter while keeping vital diagnostics within constant view. Whether you're running a high-performance center console, tournament bass rig, or offshore cruiser, this gauge system delivers the precision monitoring that separates casual boating from championship-level vessel management.

Built by QUICKCAR RACING PRODUCTS—a name trusted in motorsport and marine instrumentation—the Extreme 4-1 integrates a 5-inch tachometer alongside all four pressure and temperature sensors, giving you engine speed and load data at a glance. The combined gauge face design allows simultaneous monitoring of oil pressure, coolant temperature, oil temperature, and fuel system pressure without requiring multiple instrument pods or complex wiring runs. This consolidation reduces installation footprint and weight while maintaining sensor accuracy and response time critical to detecting engine anomalies before catastrophic failure occurs. The gauge is engineered for harsh marine environments, with sealed construction that resists corrosion, salt spray, and vibration inherent to high-speed or extended-use boating operations.

Tournament anglers, commercial operators, and power boaters benefit most from the Extreme 4-1's comprehensive monitoring capability, particularly those running modified or heavily used engines where predictive maintenance prevents downtime during critical fishing days or scheduled charters. Installation suits inboard, outboard, and stern-drive configurations where space efficiency and clear visibility from the helm are non-negotiable. The 5-inch dial provides excellent readability in direct sunlight and varying lighting conditions, essential when navigating tight water or making split-second power decisions. Weighting approximately 5.35 lbs and measuring 8.4 x 6.7 x 20.1 inches, the complete assembly mounts cleanly to standard dash panels or custom consoles with minimal structural modification required.
