Properly wired float switches should function with or without the battery switch being turned on, so be sure to check both ways. Most boats are also wired so that the operator can manually toggle the bilge pump on. Check to see if the pump runs properly and that your bilge wiring, discharge hose, hose clamps, and thru-hull fitting are all in great shape. If your boat’s freshwater system was winterized, be sure to fill your tanks and flush antifreeze from the system, and dispose of it per the manufacturer’s recommendations.

When you turn the key and that V6 or V8 fires up with a steady hum, you know every piece of the system is doing its part. A good serpentine belt doesn’t call attention to itself, but you can feel the difference when it’s the right one—clean, smooth power delivery and no surprises while you’re out enjoying a long afternoon on the water. This Mercury Marine part keeps your engine’s heartbeat steady, no matter if you’re pulling away from the dock or powering through a long stretch of open lake.\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\"\u003eDesigned for MerCruiser V6 and V8 engines with closed cooling systems\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eBuilt for 2001–2016 Alpha and Bravo configurations\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eMeasures 2,704mm for precise factory-matched fit\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCrafted from a durable rubber composite designed for marine use\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eMatches the original belt installed by MerCruiser\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEngineered for stable tension, clean tracking, and long service life\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 2001–2016 MerCruiser V6 and V8 (305 and 350 cubic inch) engines\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eWorks with Alpha sterndrives using closed cooling systems\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCompatible with Bravo sterndrives using standard cooling\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eFits serial numbers 0M320025 through 2A455872\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCommon on runabouts, family cruisers, tow boats, and performance-oriented vessels\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eSuitable for both sterndrive and inboard configurations using this specific accessory layout\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 A proper serpentine belt is one of the most underrated performance parts on the boat.
