Waterproof SMI 2 Gauge Panel OP/WT

The Waterproof SMI 2 Gauge Panel OP/WT by Longacre is a marine-grade instrument cluster engineered for serious boaters and anglers who demand reliable real-time engine diagnostics in harsh saltwater and freshwater environments. This dual-gauge assembly monitors both oil pressure and water temperature—two critical parameters that separate a well-maintained vessel from one headed toward catastrophic engine failure. Whether you're running a center console, trawler, or performance speedboat, this waterproof panel delivers the visibility and protection your engine deserves.

Built around two 2 5/8-inch analog gauges with a professional black face and integrated warning light system, the SMI 2 Gauge Panel combines proven mechanical gauge accuracy with electronic alert capability. The waterproof construction shields internal components from salt spray, spray washdown, and high-humidity bilge conditions that corrode standard instruments within a season. Analog needle display eliminates dependence on LED screens that fade in bright sunlight, while the warning light circuit triggers audible or visual alerts when oil pressure drops or water temperature climbs into danger zones. This redundancy—analog plus digital warning—gives you multiple layers of engine protection on the water.

Anglers running all-day trips and tournament competitors benefit most from this setup; the compact 6.5 x 6.5-inch mounting footprint fits standard dash openings without major modification. Installation includes full gauge kit assembly, keeping wiring and sensor consolidation straightforward. The 1.55-pound weight has minimal impact on weight-sensitive fishing rigs, while the proven Longacre pedigree in marine and performance applications ensures parts availability and long-term support throughout your boat's service life.
