It reads 0 to 7000 RPM on a clean black face with a white needle, and tracks total engine hours so you always know when the next service is due.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Sierra Marine Amega 68443P is a 3-inch tachometer with a built-in digital hour meter, and it's the gauge you reach for when you want engine RPM and run-time tracking in a single dial. It reads 0 to 7000 RPM on a full-sweep analog needle, so you get a smooth, easy-to-read display that most boaters find quicker to scan at a glance than a bare digital number. The black face, black bezel, and white pointer needle give it a clean, factory look that fits right in on most center consoles and dash panels.\u003c\/p\u003e\n\u003cp\u003eHere's what makes this one handy. That little digital hour meter tucked into the dial face keeps a running total of engine hours, which is exactly what you need for staying on top of oil changes, impeller swaps, and the rest of your service schedule. No more guessing when the last service was. The hour meter runs off ignition power, so keep in mind it counts any time the key is on, not strictly when the engine is turning. If you tend to leave the key on while rigging or listening to the stereo at the dock, your hours will read a touch high.\u003c\/p\u003e\n\u003cp\u003eInstallation is straightforward for anyone comfortable behind the dash. The gauge drops into a standard 3-inch mounting hole, the same cutout most factory clusters already use. You'll wire it to switched 12-volt power, ground, the sender signal, and the lighting circuit. The tach signal comes off the alternator tap or the ignition coil depending on your engine. Some outboards, especially certain 4-stroke setups, need the signal calibrated or run through a tach adapter to read the full 0-7000 range accurately. It's worth checking your engine's manual before you button everything up.\u003c\/p\u003e\n\u003cp\u003eOne thing we'll be straight about. This is the version without peak memory and without a warning indicator, so it won't store your max RPM or flash an over-rev alarm. If you run a high-strung 2-stroke and want an over-rev warning, you'll want a separate alarm for that. For most cruising, fishing, and pontoon setups, the plain tach-plus-hours combo is all you really need, and it keeps the dial uncluttered.\u003c\/p\u003e\n\u003cp\u003eLighting is covered with thru-dial and perimeter lighting, so the whole face glows evenly at night instead of lighting from one spot. The white needle on the black face is sharp in shade, though like a lot of light-on-dark gauges it can wash out a bit in direct midday sun. Wiring the lighting to your dash dimmer solves that and lets you knock the glow down on night runs so it doesn't kill your night vision.\u003c\/p\u003e\n\u003cp\u003eA couple of rigging tips from the crew. The electric sender signal can pick up interference from VHF and stereo wiring, so route the signal wire away from power and antenna cables to keep the needle steady. And if you're building out a matching set, this gauge is part of Sierra's Amega series, so it pairs cleanly with the matching Amega 3-inch fuel, volt, and speedometer gauges for a consistent look across the dash. Just check your behind-dash clearance first, since the bezel and body need a little depth.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Anyone repowering, replacing a dead or fogged-up tach, or building a fresh gauge panel on a runabout, center console, pontoon, or small cruiser. It's built to the same standards Sierra applies across its marine line, made to hold up to the salt, damp, and vibration that kill cheaper gauges. Sierra has been supplying OEM engine builders and boat manufacturers for years, and that same quality carries into the aftermarket gauges. If you want reliable RPM and honest engine hours in one clean 3-inch dial, the 68443P earns its spot on the dash.\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 analog dial for quick, at-a-glance RPM reads\u003c\/li\u003e\n  \u003cli\u003e0 to 7000 RPM range covers most gas outboard and inboard engines\u003c\/li\u003e\n  \u003cli\u003eBuilt-in digital hour meter tracks total engine hours for service scheduling\u003c\/li\u003e\n  \u003cli\u003eFull-sweep electric movement for a smooth, steady needle\u003c\/li\u003e\n  \u003cli\u003eThru-dial and perimeter lighting for even, glare-free night visibility\u003c\/li\u003e\n  \u003cli\u003eBlack face, black bezel, and white pointer needle for a clean factory look\u003c\/li\u003e\n  \u003cli\u003eStandard 3-inch mounting hole drops into most factory dash cutouts\u003c\/li\u003e\n  \u003cli\u003ePart of the Sierra Amega series for a matched dash of fuel, volt, and speed gauges\u003c\/li\u003e\n  \u003cli\u003eEngineered for the marine environment to resist salt, moisture, and vibration\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 engines does this tachometer work with?\u003c\/summary\u003e\n    \u003cp\u003eIt reads 0 to 7000 RPM, which covers most gas outboard and inboard marine engines.
