Mercury / MerCruiser Quicksilver Exhaust Shutter ā 15982
The Mercury Quicksilver 15982 Exhaust Shutter is a genuine OEM exhaust flapper valve used in many MerCruiser sterndrive exhaust systems. It installs inside the exhaust outlet to allow exhaust gases to exit the engine while helping prevent water from flowing back into the engine through the exhaust.
Key Details
-
Part Number: 15982
-
Type: Exhaust shutter / exhaust flapper
-
OEM Brand: Mercury Marine / Quicksilver
-
Installation Location: Exhaust elbow or Y-pipe outlet
-
Sold: Individually
Function
The exhaust shutter performs two important roles in a marine engine:
-
Allows exhaust gases to exit the engine normally.
-
Prevents backflow of water into the exhaust manifold and cylinders.
This protection is critical when the boat suddenly stops or reverses, where water pressure in the exhaust system can surge backward.
Typical Applications
Commonly used on many MerCruiser sterndrive engines, including:
-
4.3L V6
-
5.0L V8
-
5.7L V8
-
Various Alpha and Bravo drive exhaust systems
Exact compatibility varies by exhaust elbow and Y-pipe design.
Service Tip
Exhaust shutters should be inspected periodically because they can:
-
Melt or warp from exhaust heat
-
Break apart and restrict exhaust flow
-
Fail to block water reversion
A damaged shutter can allow water intrusion into the engine, which can lead to severe engine damage.
ā ļø Fitment Tip:
Always verify the correct shutter using the engine serial number and exhaust assembly diagram in the Mercury parts catalog.
