That confidence doesn’t come from the engine alone. It comes from every component working together, right down to the hardware holding your props in place. The Mercury 8M0176915 Rear Prop Nut is one of those pieces you rarely think about until you need it, but it’s the reason the whole drive system feels tight, smooth, and ready for whatever the day brings. Offshore, inlets, long runs to the reef — it’s one of those parts that simply does its job so you can focus on the water ahead.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan data-preserver-spaces=\"true\"\u003eKey Features\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eSecures the \u003c\/span\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003erear propeller\u003c\/span\u003e\u003c\/strong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e in a Mercury V12 contra-rotating prop system\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eBuilt from \u003c\/span\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003ehardened, marine-grade brass\u003c\/span\u003e\u003c\/strong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e for long-term strength and corrosion resistance\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003ePrecision-machined to handle extreme torque and load\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEngineered to exceed Mercury Marine’s factory performance and durability requirements\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eMercury Marine part number \u003c\/span\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e8M0176915\u003c\/span\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eThis genuine Mercury Marine part is designed for:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eMercury 7.6L V12 600hp Verado outboards\u003c\/span\u003e\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eMercury 7.6L V12 500hp SeaPro outboards\u003c\/span\u003e\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eIdeal for large center consoles, offshore fishing boats, heavy commercial vessels, sport cruisers, and high-end multi-engine setups\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cspan data-preserver-spaces=\"true\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eIn a contra-rotating setup, the rear prop takes a tremendous share of thrust and load. That means the nut holding it in place needs to be absolutely trustworthy.

When you settle into a long cruise, the ride stays smooth because everything behind the transom is locked down exactly as it should be. And when you’re working in rough conditions or running a heavy hull, this brass nut keeps the prop secure without loosening or deforming under stress. It’s a small part, but on a V12, it carries a big responsibility.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eInstallation is straightforward and familiar for anyone used to working with Mercury hardware.
