Service & Installation Notes
General service guidance only. Use the service manual for your exact engine and exhaust configuration.
- Allow the engine and exhaust system to cool completely, shut off the battery switch, and secure the ignition to prevent accidental starting.
- Drain the cooling passages in the manifold and elbow assembly as directed by your MerCruiser wet-joint service manual before loosening exhaust hoses or bellows.
- Support heavy exhaust elbows and manifolds during disassembly, and clean all mating surfaces and hose necks without gouging the metal.
- Distinguish between the upper 3-inch exhaust bellow and lower 3-inch exhaust hose positions during fit-up, ensuring proper alignment and clamp seating according to factory procedures.
- Operate the engine only with a verified cooling water supply and inspect all wet-joint connections and hose joints for exhaust or water leaks; shut down immediately if any abnormality occurs.

Because individual OEM and aftermarket numbers often refer to a single upper or lower component rather than a complete repair kit, always verify both positions separately.
