OEM MerCruiser 7.4L Big Block V8 Exhaust Manifold – Freshwater Used – Marine Application
OEM MerCruiser 7.4L Big Block V8 Exhaust Manifold – Freshwater Used – Marine Application
Here we're selling a used OEM MerCruiser 7.4L Big Block V8 exhaust manifold removed from a freshwater marine application. Please review all photos carefully for exact condition and compatibility.
This cast iron exhaust manifold was removed from a MerCruiser 7.4L big block engine and is being sold exactly as shown. The manifold appears structurally sound with no visible cracks, breaks, or repairs noted during removal.
The exterior has been coated and shows typical cosmetic wear from marine use. The internal water passages and exhaust runners display normal surface rust scaling commonly found in used freshwater marine exhaust components. Mounting surfaces appear serviceable, but we recommend inspection and resurfacing if required before installation.
A good replacement manifold for worn, damaged, or leaking OEM exhaust systems. Please verify fitment for your specific MerCruiser, Mercury Marine, or GM-based 7.4L marine engine application prior to purchase.
