You can hear it in the tone of the exhaust and feel it in the smooth pull as you throttle up. That confidence doesn’t happen by accident — it comes from parts that keep fuel temperatures under control even when the rest of the world is heating up. The Quicksilver 8M0125846 Fuel Pump Cooler Kit is one of those quiet heroes, helping the engine stay happy so you can focus on the ride instead of worrying about vapor lock or heat-related hiccups.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eKey Features\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eHelps regulate fuel pump temperature for more consistent engine performance\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDesigned for V6 and V8 MerCruiser engines including 305, 350, 377, 454, 502, and all 496 cubic-inch models\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eSuitable for both sterndrive and inboard applications\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eMarine-grade construction designed to withstand heat and vibration\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eStraightforward installation with common tools\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eFits MerCruiser V6 and V8 sterndrive and inboard engines (305, 350, 377, 454, 502 CID) within serial numbers 0L000000–0M299999\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCompatible with all 496 cubic-inch MerCruiser engines\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eWorks with Black Scorpion sterndrive models from serial 0L000000 and up\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCommon on cruisers, bowriders, wake boats, sport boats, and classic inboard setups\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eIdeal for boaters who push their engines hard in warm climates or heavy-load situations\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e You’ll notice the difference this kit makes the moment you run the boat on a hot day.
