Troubleshooting & FAQ
What is the advantage of this stainless steel elbow over the OEM plastic one?
The primary advantage is durability. Stainless steel offers significantly better resistance to heat, pressure, and cracking compared to the original plastic (nylon) part, which can become brittle and fail over time. This makes it a long-term, reliable upgrade.
How can I confirm this part fits my specific MerCruiser engine?
This elbow fits a wide range of MerCruiser V6 and V8 engines that use a center rise exhaust manifold. The best verification method is to compare your old part's number to the cross-references listed (862210A01, 18-4224, etc.) and visually match the part to the product images.
What are common signs of a failing exhaust drain elbow?
Symptoms include visible cracks on the plastic housing, water leaks from the fitting (especially when the engine is running), and potential engine overheating if the leak is severe. It's often discovered during routine maintenance or winterization.
Is any special sealant required for installation?
No, sealant is generally not required. The included O-ring is designed to create a proper seal. Ensure the mating surface on the manifold is clean and smooth before installation.
