It raises the exhaust joint to add clearance where you need it, and it ships with the gasket, bolts, and hardware to bolt it on in one go.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you're running a standard-cooled V-6 or V-8 with a dry joint exhaust, this Sierra spacer kit gives you an extra 3 inches of height at the exhaust riser joint. That added clearance is what helps keep water from working its way back toward the manifold on boats that sit low in the stern or idle in a following sea. It's a common upgrade and a common repair.\u003c\/p\u003e\n\u003cp\u003eThe kit covers 2004 to 2016 sterndrive V-6 and V-8 engines in the 305, 350, and 377 CID sizes, plus 2002 to 2016 inboard V-8 engines in 350 and 377 CID, all in Non-EC form. Standard cooling only. So if your engine runs a closed cooling system, this isn't the right kit for it.\u003c\/p\u003e\n\u003cp\u003eEverything you need to make the joint comes in the box. The gasket, bolts, and hardware are all included, so you're not chasing down fasteners partway through the job. It's a straightforward bolt-on for anyone comfortable working around the exhaust risers.\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 spacer height, adds clearance at the dry joint exhaust connection\u003c\/li\u003e\n  \u003cli\u003eStandard cooling design, matches raw-water-cooled exhaust setups\u003c\/li\u003e\n  \u003cli\u003eFits 2004-2016 sterndrive V-6\/V-8 (305\/350\/377 CID) Non-EC engines\u003c\/li\u003e\n  \u003cli\u003eAlso fits 2002-2016 inboard V-8 (350\/377 CID) Non-EC engines\u003c\/li\u003e\n  \u003cli\u003eIncludes the gasket, bolts, and hardware, no extra parts to source\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 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 does this spacer kit do?\u003c\/summary\u003e\n    \u003cp\u003eIt raises the dry joint exhaust connection by 3 inches.
