Installation Guide

1. Ensure the engine is off, cool, and the battery is disconnected for safety.
2. Trim the sterndrive unit to the full "up" or "trailer" position for easiest access to the bellows.
3. Locate the old exhaust bellows and use a screwdriver or socket to loosen and remove both retaining clamps.
4. Carefully cut or pry the old bellows away from the transom assembly and the sterndrive bell housing.
5. Thoroughly clean the mounting grooves on both the transom and bell housing to remove any old adhesive or rubber residue.
6. Place the new clamps over each end of the new bellows before installation. Do not tighten them yet.
7. Fit the larger end of the new bellows onto the transom side first, ensuring it is fully seated in the groove.
8. Stretch the bellows and fit the smaller end onto the sterndrive bell housing, again making sure it is seated correctly.
9. Confirm the bellows is not twisted and is properly aligned in its grooves.
10. Position the clamps into the grooves over the bellows and tighten them securely.
11. Reconnect the battery and start the engine, checking for any signs of exhaust leaks around the new bellows connections.

Troubleshooting & FAQ

Q: How do I confirm this bellows will fit my specific Volvo Penta model?
A: Check your engine model and year against the 'Compatible Engine Models' table. Also, verify that your existing part number matches one of the numbers listed in our 'Part Number Cross-Reference' section, such as 876631, 875848, or Sierra 18-2758.

Q: What are the signs that my old exhaust bellows needs replacement?
A: Common signs of a failed bellows include visible cracks, brittleness, or splits in the rubber. You may also notice water leaking into the bilge or a louder-than-normal exhaust sound, which indicates a leak.

Q: How often should I inspect or replace my exhaust bellows?
A: It is recommended to inspect your exhaust bellows annually for any signs of wear, cracking, or damage. Replacement intervals vary based on usage (freshwater vs. saltwater) and exposure, but they are typically replaced every 2-3 years as preventative maintenance.

Q: What is the difference between this aftermarket bellows and the original Volvo Penta part?
A: Our bellows is designed to meet or exceed OEM specifications for fit and function, using high-quality marine-grade neoprene rubber. The accordion-style design ensures the same flexibility and watertight seal as the original, but at a more competitive price point.
