Sierra 18-1916 Exhaust Riser 8-Inch for Crusader Marine Engines

The Sierra 18-1916 is an 8-inch exhaust riser extension engineered specifically for GM-based Crusader marine engines. This heavy-duty cast iron component raises the exhaust elbow above the waterline to prevent water from traveling back into the engine when throttling down.

Key Features:

• 8-inch (203.2mm) riser height measured from center of inlet to center of outlet
• Heavy-duty cast iron construction with uniform wall thickness using special casting techniques
• Primed and painted for added durability and corrosion protection in harsh marine environments
• Leak tested prior to painting to ensure quality
• Machined mating surfaces eliminate additional preparation for proper sealing
• Direct OE replacement, fully interchangeable with original equipment

Applications: Compatible with Crusader small block V8 engines (305-350 CID models 220 & 270) and big block V8 engines (454 CID models CH350 & 454XL). Works with Sierra manifolds 1925, 1926, 1933, and 1929. Requires Sierra gasket 0305 and mounting kit 8519 (sold separately).

OEM Cross-References: Replaces Crusader 97169, Barr CR-20-97169, Mallory 9-40410, and Osco 7169.
