• Soot or oil staining tracking out from the flange
• Loss of power or boost pressure under load
• Gasket found blown, split or crushed unevenly on strip-down
• Fasteners at the flange found slack

🛠️ Service Notes

• This joint is part of the emergency stop arrangement, so prove the stop shuts the engine down properly after the joint has been disturbed and before the boat is used
• Clean both faces and check the flange for distortion before fitting
