Product Details
This aftermarket Exhaust Elbow Gasket is designed to seal the joint between a marine engine exhaust elbow or riser and its mating surface. A properly fitted gasket helps prevent exhaust, cooling-water, and carbon deposits from escaping at the connection.
Catalog evidence identifies manufacturer part number 3863191 as an exhaust elbow gasket and shows it in a Volvo V8 5.0/5.7L GM 305 and GM 350 CID application context beginning in 1993. Fitment can vary by engine configuration, exhaust-elbow design, and model year, so verify the part number and gasket shape before ordering.
- Replacement gasket for a marine exhaust elbow or riser connection.
- High-temperature gasket material suitable for marine exhaust sealing applications.
- Designed for a direct-fit installation when the replacement matches the original gasket and mounting pattern.
- Sold as a two-gasket package.

Troubleshooting and FAQ
How do I confirm fitment?
Compare the reference number on your original gasket or service documentation with 3863191, then verify the engine model, year, exhaust-elbow or riser design, gasket outline, openings, and bolt-hole pattern. Applications that appear similar may use different gasket designs.
What are common signs of a failed exhaust elbow gasket?
Possible symptoms include exhaust noise at the joint, visible soot or carbon deposits, cooling-water leakage, exhaust odor, or moisture around the exhaust elbow. Inspect the complete exhaust assembly and follow the engine manufacturer's diagnostic procedure.
Should an exhaust elbow gasket be reused?
No. Replace the gasket whenever the exhaust elbow or riser is removed unless the applicable manufacturer service instructions specifically state otherwise.
Can I reuse the original fasteners?
Inspect all fasteners for corrosion, damaged threads, heat damage, or stretching. Replace them when required by the service manual or when their condition is unsuitable, and tighten them only to the manufacturer's specified torque.
Is this an OEM component?
This listing is for an aftermarket replacement gasket. The referenced manufacturer part number is provided for comparison and identification; the replacement is not represented as an original manufacturer component.
Are dimensions and horsepower ranges included?
No fixed dimensions or universal horsepower range are specified for this listing. Exhaust-system fitment depends on the exact engine and elbow or riser configuration, so verify the original part and mounting pattern before ordering.
Safety and Important Information
- Never work on a hot engine or exhaust system.
- Verify the original part number, gasket shape, openings, and bolt pattern before installation.
- Follow the engine and boat manufacturer's service procedures, torque specifications, and exhaust-system safety requirements.
- After installation, check carefully for exhaust and cooling-water leaks before returning the boat to service.
- Professional installation is recommended when the exhaust system or engine service procedure is unfamiliar.
