Keep tabs on every surge of power with the Mercury SC1000 Tachometer (79-8M0135634)—a 7 000 RPM smart gauge that slips into the standard 85 mm cut-out already in your dash. The crisp white face and scratch-resistant glass lens are easy to read in full sun, while soft backlighting keeps the numbers clear during those dawn runs to the fishing grounds. Plug it into your SmartCraft harness and the gauge springs to life, pulling real-time data straight from any SmartCraft-compatible outboard or sterndrive.

What sets it apart

• SmartCraft savvy: displays RPM plus Speed-based SmartTow cues; software v9.0 also supports Active Trim, Active Exhaust, and oil-level readouts.

• Drop-in fit: 85 mm (3-3/8") mount matches most factory holes; bezel options let you match existing instrumentation.

• Built for the elements: sealed electronics and marine-grade connectors shrug off spray, vibration, and salt.

• User-friendly setup: push-button menu lets you tailor alarm points, lighting, and cylinder count without digging through manuals.

Whether you’re dialing in a perfect wake for tubing or chasing maximum fuel efficiency on a long cruise, this SC1000 tach gives you the precise feedback you need—right where you can see it, without the clutter of extra screens.
