Waterproof SMI 2 Gauge Panel W/Tach OP/WT

The Waterproof SMI 2 Gauge Panel W/Tach OP/WT by Longacre is a marine-grade instrument cluster designed for serious boaters and anglers who demand reliable real-time engine diagnostics at a glance. This analog gauge assembly combines three critical engine parameters—oil pressure, tachometer, and water temperature—into a single compact faceplate that mounts securely in tight helm spaces. Built to survive saltwater spray, vibration, and temperature swings, this gauge panel is engineered for commercial fishing vessels, center consoles, and performance boats where engine health monitoring can mean the difference between a productive day on the water and a costly breakdown.

The panel features an elite-grade waterproof construction with a black face that reduces glare in direct sunlight and improves readability from the captain's chair. The analog dial design eliminates electronic lag and provides intuitive mechanical feedback—oil pressure and water temperature indicators respond instantly to engine load changes, while the tachometer tracks RPM with zero latency, critical for fuel efficiency and throttle management. The assembly incorporates an integrated warning light system that alerts operators to out-of-range conditions before they become catastrophic. At 6.75 by 6.55 inches with a 14.45-inch depth, the gauge panel fits standard 6-inch and 2 5/8-inch diameter gauge openings found on most marine dashboards, and the complete kit includes all necessary wiring and fittings for straightforward installation.

This gauge panel is ideal for boat owners upgrading aging instruments or installing reliable monitoring on older or custom-built vessels where OEM electronics are unavailable or incompatible. Whether you pilot a commercial fishing operation, run a charter fleet, or maintain a personal performance watercraft, the Waterproof SMI 2 Gauge Panel W/Tach OP/WT delivers the durability and accuracy needed for salt-air environments and extended duty cycles. The analog architecture requires no software updates and resists electromagnetic interference from modern marine electronics, making it a time-tested solution for captains who prioritize dependability over digital complexity.
