Mercury Quicksilver 14358001 is a genuine OEM exhaust bellows tube, oval shape for select MerCruiser sterndrive installations. Mercury's current product listing identifies it specifically as an exhaust bellows tube for select V6 and V8 MerCruiser sterndrive engines.
Key Features
- Genuine Mercury / Quicksilver OEM part number 14358001.
- Officially described by Mercury as an exhaust bellows tube, oval shape.
- Built for select V6 and V8 MerCruiser sterndrive engines.
- Current cross-reference sources also describe it as a 4-inch lower exhaust tube / MerCruiser exhaust boot.
Engine Compatibility
The strongest supportable fitment for 14358001 is select MerCruiser V6 and V8 sterndrive engines. That is the clearest current OEM guidance. Current cross-reference listings also commonly associate this tube with older Alpha and Bravo V6/V8 sterndrive exhaust applications, but the safest match is by exact MerCruiser sterndrive parts diagram and serial range.
Serial Number Fitment Notice
Verify fitment by exact engine serial number, drive model, and the correct exhaust / bellows diagram before ordering. Mercury's current listing specifically directs owners to the owner's manual or service manual for exact application confirmation.
When This Part Needs Replacement
Replace this tube when the existing exhaust bellows tube is cracked, split, hardened, loose, heat-damaged, or leaking in the sterndrive exhaust passage. In practical service terms, it is also commonly replaced during bellows or transom-service work when the drive is already apart. This guidance is a practical service inference based on the part's documented role as the exhaust bellows tube.
Installation Notes
Install 14358001 only after confirming the correct MerCruiser exhaust bellows application for the drive being serviced. Because this is the oval-shape exhaust tube, it should be matched to the correct sterndrive exhaust layout rather than ordered by appearance alone.
Alternate/Superseded Part Numbers
Current sources connect older Mercury / MerCruiser references 14358 and 14358T to 14358001. Some cross-reference sources also show a later supply replacement path to 8M0199680, but the clearest active Mercury retail listing remains 14358001.
Parts Desk Insight
With exhaust bellows parts, the important match is the exact bellows style and drive family. A quick serial-number check usually saves more time than trying to match an exhaust tube by shape alone.
