Troubleshooting & FAQ
How do I confirm this elbow fits my MerCruiser engine?
This elbow is designed for most MerCruiser V6 and V8 engines from the 1990s–present that use center-rise exhaust manifolds. The best way to ensure fitment is to verify your part number against the cross-reference list (e.g., 22-862210A01, 22-806926A1) or visually compare your current part to our product images.
The original OEM part is stainless steel, but this one is plastic. Is that okay?
Yes. While the original part is metal, our aftermarket elbow is constructed from high-strength, marine-grade Nylon PA66 plastic. This material provides excellent durability and resistance to corrosion in marine environments, offering comparable performance and a longer service life than lower-grade plastics.
What is the thread size for this fitting?
This drain elbow uses a standard 3/4" NPT (National Pipe Thread) connection, which is common for this application on MerCruiser manifolds.
