BBabe Complete Riser Kit for MerCruiser V6 V8 Engines Cast Iron with Gaskets Bolts

This exhaust manifold riser kit delivers a direct replacement solution for MerCruiser small and big block V6 and V8 engines from 1981 to 2002. Constructed from high-strength cast iron with a protective outer coating, it resists corrosion in both freshwater and saltwater marine environments, extending service life. The kit includes cast iron riser elbows, matched gaskets, and installation bolts, all engineered to meet OEM standards for wet joint systems. Its optimized internal flow enhances exhaust circulation, helping to boost engine power output while reducing fuel consumption for more efficient operation.

The durable cast iron structure withstands extreme engine heat and ongoing vibration, lowering the risk of manifold cracks, gasket leaks, and blowouts. With approximate assembled dimensions of 14.2 inches in length, 15.0 inches in width, and 9.8 inches in height and weighing about 49.6 pounds, it provides a robust replacement when maintaining or repairing your marine engine. Always verify compatibility with your specific engine model and year before installation. This kit is intended for indoor engine compartments and should be installed following standard marine engine service procedures. Regular inspection can help maintain performance and catch early wear.
