🔄 Supersession & Cross Reference

OEM Supersession Chain

• 41616A2 is the later documented manifold for the applicable serial range
• 98348A2 is the earlier related manifold used below the 41616A2 serial break
• The two assemblies are serial-controlled and should not be treated as universally interchangeable

OEM / Related Numbers

• 41616A2
• 98348A2 earlier related intake manifold
• 22-73817 related manifold fitting
• 32-89713 related manifold-to-reservoir hose
• Related four-barrel carburettor and throttle linkage
• Related intake gasket and water-tube flange components

Aftermarket / Verified Equivalents

• No verified new aftermarket complete manifold
• Used genuine 41616A2 manifolds are the direct replacement
• Aftermarket carburettors, carburettor kits and intake gaskets are available separately
• Automotive manifolds are not direct marine replacements because cooling passages and corrosion protection differ

📦 Condition

• Genuine used part
• Removed from running engine where applicable
• In good working condition unless otherwise stated
