Troubleshooting & FAQ
How do I know if this gasket will fit my engine?
This gasket is made for Parsun 5HP 4-stroke outboards (models 4AC, MSHKZ, AS, 5C, CMH, CS) and cross-references Yamaha part 6E0-45315-A0. The best way to ensure a match is to check your engine's service manual or examine the part number on the old gasket.
What are the signs of a failed water pump base gasket?
Common symptoms include water leaking from the seam between the gearcase and the drive shaft housing, engine overheating alarms, or a noticeably weaker water stream from the tell-tale outlet, indicating a loss of cooling system pressure.
Do I need to use sealant with this gasket?
Generally, this type of hermetic gasket is designed to be installed dry. The material compresses to form a tight seal without chemical sealants. Using sealant can sometimes cause the gasket to slip or not compress evenly. Always follow the recommendations in your engine's official service manual.
Can I reuse my old gasket?
No. Gaskets are considered single-use components. They create a seal by being compressed and deformed. Once the pressure is released, they lose their ability to form a reliable, leak-proof seal and must be replaced.
