About this part
This exhaust Y-pipe service kit for MerCruiser stern drive exhaust installations contains two lower exhaust bellows referenced to 32-14358T, two upper exhaust bellows referenced to 32-44348T, and two exhaust water shutters referenced to 807166A3.
The three primary reference numbers identify separate upper, lower, and water-shutter components rather than interchangeable complete-kit numbers, so confirm that your exhaust arrangement requires all three component references before ordering.
Match the application
Use this kit when servicing a MerCruiser stern drive exhaust Y-pipe installation that calls for both 4-inch upper and lower exhaust bellows together with 807166A3-type water shutters.

Workshop sequence
General workshop guidance only; use the service procedure for your exact drive or engine configuration.
- Separate and match each component by reference before disassembly: 32-44348T is for the upper exhaust bellows position and 32-14358T is for the lower exhaust bellows position. Even though both are 4-inch exhaust components, do not swap their installation locations.
- Compare the replacement water shutters against the existing Y-pipe mounting hardware and verify that your exhaust pipe uses the 807166A3 suffix style rather than 807166A1 or 807166A2.
- Inspect the exhaust Y-pipe, risers, elbows, and mating necks for corrosion, heat damage, or loose shutter fragments, then install the water shutters and upper and lower bellows in the orientation and clamp arrangement specified by the service manual for your engine and drive package.
Questions from the workshop
Are the 32-14358T and 32-44348T exhaust bellows interchangeable since both are 4-inch components?
No. Although both are described as 4-inch exhaust components, 32-14358T identifies the lower exhaust bellows and 32-44348T identifies the upper exhaust bellows. Each serves a different position in the exhaust installation.
Can 807166A3 water shutters replace 807166A1 or 807166A2 directly?
Do not assume 807166A1, 807166A2, and 807166A3 are interchangeable. Check the complete water-shutter part number and suffix required by your specific exhaust Y-pipe configuration before ordering.
