Black face, white needle, and built-in illumination for night running. It's a clean, no-nonsense RPM gauge for 12-volt gas outboards, sterndrives, and inboards, and it drops right into a standard 3-inch helm cutout.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Sierra Marine 62724P is a 3-inch electric tachometer from the Premier Pro series, and it does one job well. It shows you exactly what your engine is turning, right now, at a glance. Black face, black bezel, a crisp white pointer needle, and built-in illumination for running after dark. It reads 0 to 6000 RPM on a full sweep dial and runs off standard 12-volt DC power. If you're rebuilding a helm or replacing a tired old gauge that's gone foggy or quit sweeping, this is a clean, straightforward swap.\u003c\/p\u003e\n\u003cp\u003eFull sweep is the part that matters day to day. The needle travels across nearly the whole face, so the difference between 3200 and 3600 RPM is a real, readable gap instead of a tiny twitch near the top of the dial. That's the kind of resolution you want when you're dialing in a prop, holding a trolling speed, or just keeping an outboard off the rev limiter on a long run. It's an analog gauge, so there's no menu to scroll and nothing to boot up. Key on, and it's working.\u003c\/p\u003e\n\u003cp\u003eThis one's an electric tach, so it reads engine speed off an electrical signal rather than a mechanical cable. On most gas outboards and sterndrives that signal comes off the alternator's AC tap or the ignition. The important thing at install time is matching the tach to your engine's pulse output, sometimes called the poles or pulse setting. Get that right and the reading is dead accurate. Get it wrong and you'll see double or half the real RPM, which is the single most common head-scratcher people run into. Route the signal wire away from your 12-volt power runs too, or you can get a little needle bounce on twin-engine rigs.\u003c\/p\u003e\n\u003cp\u003eThe 62724P drops into a standard 3-inch gauge cutout, roughly 3-3\/8 across, the same hole most helms are already cut for. On older runabouts and center consoles that's usually a direct fit. On some newer boats with metric dash openings you may need a simple adapter ring to snug it up. The illumination ties into your panel's dimmer circuit, so it dims down with the rest of your gauges at night. One tip from experience: if you're running LED nav lights on the same circuit, add a small load resistor to keep the backlight from flickering.\u003c\/p\u003e\n\u003cp\u003eBe clear on what this version is and isn't. This is the straightforward model, without peak memory and without a warning indicator. It won't hold your maximum wide-open-throttle RPM for later, and it won't flash an over-rev alarm. For a lot of boaters that's exactly right. You just want a clean, honest RPM readout and nothing extra to fuss with. If you track WOT numbers for prop selection or run a high-output engine that you want an over-rev buzzer on, look at the Sierra tachs that add peak memory and warning functions, or pair this one with a separate hour meter.\u003c\/p\u003e\n\u003cp\u003eStyling-wise, the black-on-black look with the white needle is about as classic as a helm gets, and it matches most modern dash layouts without standing out. It's a Sierra part, so it's built to hold up to salt, spray, and UV the way marine gear has to. Out on the water, gauges take a beating that dash gear in a car never sees. Salt, humidity, pounding chop, and constant vibration all work against the electronics and the movement inside. A rinse of fresh water on the helm now and then goes a long way. Whether you're rigging a fishing skiff, refreshing the helm on a cruiser, or bringing an older sterndrive boat back to life, this is one of the gauges you actually watch every trip. If you're not sure it's the right tach for your engine, give us a shout with your make and cylinder count and we'll point you at the correct setup.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e3-inch full sweep dial reads 0 to 6000 RPM and spreads the needle across the whole face so small RPM changes are easy to see\u003c\/li\u003e\n  \u003cli\u003eElectric drive reads engine speed off the alternator or ignition, no mechanical tach cable to route or replace\u003c\/li\u003e\n  \u003cli\u003eAnalog gauge with instant key-on readout, no menus and nothing to boot up\u003c\/li\u003e\n  \u003cli\u003eBlack face, black bezel, and white pointer needle for a classic helm look that matches most dash layouts\u003c\/li\u003e\n  \u003cli\u003eBuilt-in illumination ties into your panel dimmer for clear night running\u003c\/li\u003e\n  \u003cli\u003eRuns on standard 12-volt DC boat power\u003c\/li\u003e\n  \u003cli\u003eFits a standard 3-inch gauge cutout for a direct one-for-one replacement on most helms\u003c\/li\u003e\n  \u003cli\u003ePremier Pro series build for marine duty, made to hold up to salt, spray, and UV\u003c\/li\u003e\n  \u003cli\u003ePulse setting matches the tach to gas outboard, sterndrive, and inboard engines for accurate RPM\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Sierra Marine reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat RPM range does the 62724P read?\u003c\/summary\u003e\n    \u003cp\u003eIt reads 0 to 6000 RPM on a full sweep analog dial, so the needle covers nearly the whole face and small changes in engine speed are easy to see.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eIs this an electric or a mechanical tachometer?\u003c\/summary\u003e\n    \u003cp\u003eIt's an electric tach.
