Troubleshooting & FAQ
How do I know if this exhaust elbow fits my specific engine model?
This elbow is designed for the Yanmar 4LH series. Always compare the part number (119171-13530), dimensions, and photos on this page to your existing part before ordering. If your model is in the 4LH series but you are unsure, verifying with a mechanic is recommended.
What are common signs that my exhaust elbow is failing?
Signs of a failing exhaust elbow include water leaks (external or internal), engine overheating, loss of power, excessive smoke, or visible corrosion and cracks on the elbow itself. A leaking elbow can cause catastrophic engine damage if not replaced promptly.
What is the advantage of a stainless steel elbow versus an OEM cast iron one?
Stainless steel offers superior corrosion resistance compared to traditional cast iron, especially in harsh saltwater environments. This extends the part's service life and reduces the risk of leaks and blockages over time.
Do I need to use a new gasket for installation?
Yes, it is highly recommended to use a new gasket (such as REC119171-13510, sold separately) during installation to ensure a proper, leak-free seal between the elbow and the manifold.
How often should a marine exhaust elbow be inspected?
Regular inspection during routine engine maintenance (at least annually) is critical. However, replacement intervals can vary widely based on usage (freshwater vs. saltwater), operating hours, and engine temperature. Replace it immediately if any signs of failure are detected.
OEM vs. Aftermarket?
This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
