Product Description
Mercury Quicksilver 19-821908 is the replacement top plug for specified Sport Jet flushing attachments. The cap closes the flushing connection when the attachment is not in use.
Product Compatibility
Fits the consumer-use flushing attachment for 90, 95 and 120 Sport Jet engines, and the standard flushing kit used on Sport Jet 175, 200 OptiMax, 210 and 240 EFI jet drives.
Fitment Notice
Confirm the flushing-attachment assembly before ordering. The 120XR powerhead flushing-kit diagram identifies this plug as item 2, alongside separate sealing washer 12-821915.
Replacement and Installation
Replace a missing or damaged plug and inspect the associated washer. Follow the engine's flushing procedure; this cap does not change whether a particular flushing attachment permits the engine to run.
Alternate Part Numbers
OEM catalog number: 19-821908. Bare part-number reference: 821908.
Parts Desk Insight
Match the cap to the flushing attachment, not simply the engine horsepower. The sealing washer is a separate catalog component.
