Troubleshooting & FAQ
How do I know if this elbow is the correct fit for my engine?
This elbow is designed for Yanmar 6LY series engines. The best confirmation method is to match your existing part number to one of the numbers listed in our Part Number Matrix. Also, visually compare your current elbow to our product images and specifications before ordering.
What is the advantage of stainless steel over the original cast iron elbow?
Stainless steel offers significantly better resistance to corrosion and rust, especially in saltwater environments. This leads to a much longer expected lifespan (10+ years) compared to the original cast iron parts, which are prone to internal rusting and blockage over time.
How often should this part be inspected?
It is good practice to inspect the exhaust elbow annually for any signs of leaks, corrosion, or blockages as part of your regular engine maintenance schedule. While its lifespan is significantly longer than cast iron, preventative checks ensure optimal engine performance.
What are the signs of a failing exhaust elbow?
Common symptoms include engine overheating, steam in the exhaust, water leaks (either externally or internally into the cylinders), reduced engine power, and a visible increase in corrosion or rust on the elbow's exterior.
Is a gasket included with this elbow?
No, this product includes only the exhaust elbow as shown. We strongly recommend purchasing and installing a new, high-quality gasket to ensure a proper seal and prevent dangerous exhaust leaks.
Why is the elbow galvanized if it's already stainless steel?
The galvanization coating on the stainless steel provides an additional layer of protection against galvanic corrosion and harsh saltwater environments, further enhancing its durability and longevity.
