Waterproff SMI 4 Gauge Panel OP/WT/OT/WP

The Longacre Waterproof SMI 4 Gauge Panel (model 52-44569) is a marine-grade instrument cluster designed for serious boaters who demand real-time engine and water system monitoring. After years running offshore and cruising inland waters, you know that reliable gauges aren't a luxury—they're essential safety equipment. This analog gauge assembly consolidates four critical monitoring functions into a single, compact waterproof enclosure, eliminating the need for multiple standalone instruments and streamlining your helm setup.

The panel combines oil pressure, oil temperature, water temperature, and water pressure gauges with a black face dial design and integrated warning light function, allowing you to catch system anomalies before they become catastrophic failures. Longacre's SMi Elite construction delivers true waterproof sealing—essential when operating in salt spray, rain, and high-moisture environments where standard gauges fail prematurely. The 4-gauge configuration means you're monitoring engine lubrication health, thermal performance, raw-water cooling integrity, and fuel or hydraulic system pressure simultaneously, giving you complete situational awareness of your vessel's vitals at a glance.

This panel is ideal for retrofit installations on center consoles, hard-tops, and cabin cruisers where space is limited and clean aesthetics matter. Weighing just 2.9 lbs and measuring 6.5 × 6.31 × 14.13 inches, it fits standard dash openings and integrates easily with existing wiring harnesses on most modern engines. The included warning light function serves as a visual backup to audible alarms, ensuring you'll never miss a critical system alert whether you're focused on fishing, navigation, or heavy weather conditions.
