Clamps, sealants, tools and installation instructions are not specified as included. Reuse or replace clamps only when appropriate for the particular installation and in accordance with the applicable service procedure.

Installation Notes

  1. Turn off the engine, remove the ignition key and disconnect the battery before beginning work.
  2. Position the sterndrive according to the manufacturer’s service procedure to provide safe access to the exhaust bellows.
  3. Remove the existing clamps and carefully take off the old bellows without damaging the mating surfaces.
  4. Inspect the old bellows, clamps, drive housing and transom-side connection for corrosion, cracking or other damage.
  5. Clean and dry the mating surfaces so the replacement bellows can seat correctly.
  6. Install the new exhaust bellows in the correct orientation and fully seat both ends on their mating surfaces.
  7. Secure the bellows with suitable clamps for the application and tighten them according to the manufacturer’s service specifications.
  8. Move the drive through its permitted range and check that the bellows remains seated without twisting, folding or kinking.
  9. Before operating the boat, inspect the installation for clearance and signs of leakage.

Troubleshooting & FAQ

Is this a U-joint bellows kit?

No. This product is a single exhaust bellows boot, not a U-joint bellows kit. The listing does not include a separately specified hose clamp or installation-instruction package.

Which Volvo Penta models are listed for this bellows?

The listed Volvo Penta applications are SX-S, SX-C, SX-R, SX-M, DP-S, DP-S1 and DP-SM. Confirm the exact drive model and reference number before ordering.

Does this fit every OMC Cobra sterndrive?

No broad OMC Cobra fitment claim is made here. OMC Cobra reference 987467 is associated with the product, but the exact Cobra application should be confirmed against the original part and service information.

What is the difference between an exhaust bellows and a U-joint bellows?

An exhaust bellows seals the exhaust connection, while a U-joint bellows protects the driveshaft and universal-joint area. They are different components and should not be substituted based only on similar-looking reference numbers.

How can I tell whether the existing bellows needs replacement?

Inspect for cracks, splits, hardening, deformation, loose ends, corrosion around the clamps or signs of water and exhaust leakage. Replace the bellows if damage or loss of sealing is found.

Is this an OEM component?

No. This is an aftermarket replacement component associated with the listed Volvo Penta and OMC reference numbers.

Safety & Important Info

  • Verify the exact sterndrive model and original part before purchase.
  • Do not use a U-joint bellows or another exhaust-bellows design as a substitute without confirmed application compatibility.
  • Disconnect the battery and follow the applicable marine service procedure during installation.
  • Professional installation is recommended when access, alignment or clamp torque cannot be confirmed.
