Service & Installation Notes
General service guidance only. Use the service manual for your exact engine and exhaust configuration.
- Ensure the engine is completely shut down and cooled, and disconnect the battery or disable starting circuits to prevent accidental cranking during exhaust work.
- Drain the appropriate cooling and exhaust passages as specified in your MerCruiser closed cooling service manual before loosening manifold or Dry Joint connections.
- Support heavy exhaust manifolds and elbows during disassembly, and clean all mating surfaces thoroughly while protecting the sealing faces from scratches or gouges.
- Compare the new gaskets and seals against the Dry Joint and closed cooling passage layout on your engine to verify correct orientation before final assembly.
- After reassembly according to the engine manufacturer's fastener sequence and specifications, inspect for coolant, water, or exhaust leaks during initial operation; shut down immediately and inspect if any leakage or abnormal temperature occurs.

Questions Before Replacement
How do the 7-degree and 14-degree descriptions relate to this gasket kit?
The 7-degree and 14-degree ratings refer to the design angle of the mating MerCruiser Dry Joint exhaust elbows rather than an angle built into the flat gaskets themselves. This closed cooling kit covers GM V8 S.B. Dry Joint applications from 2002–2004 (7-degree elbow era) and 2005–2010 (14-degree elbow era).
Is this kit for standard raw-water cooling or closed cooling systems?
This kit is specifically designated as a Closed Cooling Exhaust Manifold Gasket Repair Kit for MerCruiser Dry Joint GM V8 S.B. engines (2002–2004 and 2005–2010).
