Troubleshooting & FAQ
How do I know if this housing fits my engine?
The best way to ensure compatibility is to match the part number 6EE-G4311-00-00 (or the superseded number 6BX-44311-00-00) to your existing part or service manual. While this part is made for Yamaha 4-Stroke outboards, specific model applications can vary.
What are the signs of a failing water pump housing?
Visible cracks, warping, or significant corrosion are clear signs of failure. An overheating engine or reduced water stream from the "tell-tale" outlet can also indicate a problem with the water pump system, which may originate from a damaged housing.
Can I replace just the housing and not the impeller?
While you can, it is highly recommended to replace the impeller, gaskets, and wear plate at the same time you replace the housing. These components wear together, and a complete rebuild ensures maximum reliability and performance.
What is the recommended replacement interval?
The housing itself does not have a strict replacement interval, unlike the impeller (typically every 1-2 years). The housing should be inspected during every impeller change and replaced if any signs of damage, wear, or warping are found.
Is this part difficult to install?
Installation requires disassembling the lower unit of the outboard, which is a moderately complex task. If you are not familiar with this procedure, we strongly recommend professional installation to prevent damage and ensure safety.
Is there a difference in cooling performance between this and the OEM part?
No. This aftermarket housing is manufactured to meet or exceed OEM specifications for fit, form, and function. When installed correctly with a healthy impeller and gaskets, it will provide the same cooling performance as the original part.
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.
