You are viewing a new exhaust riser spacer for MerCruiser center-rise exhaust systems from about 1985 through 2002. Replaces the 3 inch tall spacer that sits between the riser and manifold on many V6 and V8 applications. Does not come with gaskets or mounting hardware. Each "Buy It Now" is for one spacer.
