Sierra 18-4364 Exhaust Elbow Mounting Package, Open Gasket, Chrysler Inboard, Cross Reference BARR 20-0082-P

The Sierra 18-4364 Exhaust Elbow Mounting Package is an open-gasket mounting kit for Chrysler inboard exhaust manifold systems. It is built for boats using an open (raw-water) cooling arrangement rather than a closed cooling system, and it is designed to be used together with 3 1/2 inch manifold elbow risers 18-1999, 18-1907, and 18-1939. The package includes the 18-2854-1 3 inch elbow gasket (open) needed to seal the riser-to-manifold joint, plus a pipe plug, giving installers the gasket hardware required for a proper elbow reinstallation or riser swap without having to source the gasket separately.

This kit cross-references directly to BARR 20-0082-P, so it is a straightforward replacement for boats or engines originally fitted with that mounting package. Because the cooling configuration determines which gasket style is correct, buyers should confirm their system is open (raw-water) cooled before ordering this kit; boats with a closed cooling system instead require the blocked-gasket mounting package built around the 18-0476-1 elbow gasket.
