Product Description

New HGE 4354-A (4354A) aluminum exhaust riser elbow for MerCruiser V6, V8, and Big Block applications from 1983 through 2003. Riser is aluminum and has a 4" outlet and 7° down-angle. Overall riser height is 6.5". Does not replace newer dry-joint style risers, 3" outlet risers, or stainless steel risers. Fits most engine models 175, 185, 200, 205, 230, and 898. Comes with new gaskets (both blocking and open), bolts, and all necessary plugs. Accepts all original factory accessories and fittings. Each "Buy It Now" is for one riser. Riser fits either port or starboard sides.

This riser is new and high-quality aluminum construction. It is significantly lighter than the equivalent cast iron manifold. For tips on replacing exhaust manifolds and risers, see my eBay guide.
