Black face, black bezel, white needle, with thru-dial and perimeter lighting so you can read your drive angle day or night. It runs on 12 volts and matches up with a standard 2-inch trim sender. A straightforward helm gauge that just works.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Sierra 57905P is a 2-inch analog trim gauge from the Amega series, built to show you exactly where your drive or outboard is sitting. It's a clean, no-nonsense helm gauge. Black face, black bezel, and a white pointer needle that's easy to pick up at a glance. If you've got an empty 2-inch hole in your dash or you're replacing a tired old trim gauge, this one drops right in and gets you back to reading your trim without guessing.\u003c\/p\u003e\n\u003cp\u003eTrim matters more than a lot of folks give it credit for. Get your drive angle right and you plane faster, burn less fuel, and ride smoother. Get it wrong and you're plowing water or chine-walking at speed. This gauge uses a short electrical sweep, which means the needle travels a smaller arc from full down to full up. It's a simple, dependable readout that tells you where you are in the trim range. That short sweep is well suited to outboards and sterndrives where you mostly care about down, level, and up rather than fine degree-by-degree resolution.\u003c\/p\u003e\n\u003cp\u003eWhere this gauge earns its keep is at night. It's got both thru-dial and perimeter lighting, so the face glows evenly and the numbers stay readable when the sun's gone and you're idling back to the ramp. The lighting draws only about a tenth of an amp, so it's easy on your electrical system. We'd recommend wiring the light lead into your existing gauge dimmer circuit if you have one. Otherwise it sits at full brightness whenever your nav lights are on, and on a dark run you'll want to knock it down a notch.\u003c\/p\u003e\n\u003cp\u003eInstallation is straightforward for anyone comfortable behind the dash. The gauge fits a standard 2-inch mounting hole, but give yourself a little extra clearance behind the panel for the short sweep mechanism and the wiring. It runs on 12 volts DC. Watch your polarity when you wire it in. Reverse polarity will take out the internal lamp right away, so double-check your positive and ground before you power it up. The signal side connects to your engine's trim sender, and that's the part people get wrong most often.\u003c\/p\u003e\n\u003cp\u003eHere's the deal on the sender. A trim gauge only reads correctly when it's matched to the right sender resistance. If you pair this gauge with a mismatched sender, you'll see the needle swing full sweep or peg to one side no matter where your drive actually is. It's designed to work with a standard 2-inch marine trim sender, and it's a match for common sterndrive and outboard applications. If you're not sure what sender is on your rig, get us the engine make and model and we'll help you confirm the right pairing before you order. That five-minute check saves a lot of frustration on install day.\u003c\/p\u003e\n\u003cp\u003eA couple of honest notes. This is an analog gauge in a non-sealed case, so like any dash gauge in an open boat, it can pick up condensation over a few seasons if it's exposed to a lot of moisture. Mount it where it gets some protection from direct spray and it'll last longer. The black face and bezel look sharp on a modern console, though they'll show fingerprints and can fade a bit faster than a light face under constant UV in a fully open boat. Nothing unusual there, just wipe it down now and then. And it isn't built to talk to a digital network, so if your helm runs everything through a digital display, this analog gauge is a separate, standalone readout.\u003c\/p\u003e\n\u003cp\u003eFor most trailer boats, center consoles, and runabouts running a sterndrive or outboard, the Sierra 57905P is the right kind of simple. It reads your trim, lights up at night, and doesn't ask much of your wiring. Match it to the correct sender and it'll give you years of clear, at-a-glance trim readings from the helm.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e2-inch diameter face fits a standard dash cutout for a drop-in replacement\u003c\/li\u003e\n  \u003cli\u003eAmega series analog movement with a short electrical sweep for a clean up-to-down trim readout\u003c\/li\u003e\n  \u003cli\u003eBlack face, black bezel, and white pointer needle for high-contrast, at-a-glance reading\u003c\/li\u003e\n  \u003cli\u003eThru-dial and perimeter lighting for even, readable illumination after dark\u003c\/li\u003e\n  \u003cli\u003eLow lighting draw around 0.1 amp, easy on your electrical system\u003c\/li\u003e\n  \u003cli\u003e12 volt DC operation wires into standard helm power\u003c\/li\u003e\n  \u003cli\u003eMatches a standard 2-inch marine trim sender for common sterndrive and outboard rigs\u003c\/li\u003e\n  \u003cli\u003eUp-to-down scale shows the full trim range from drive down to drive up\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 size mounting hole does the Sierra 57905P need?\u003c\/summary\u003e\n    \u003cp\u003eIt fits a standard 2-inch gauge hole.
