Installation Guide

  1. Safety First: Before starting, disconnect the battery and ensure the sterndrive is trimmed up for access.
  2. Remove the Drive: Unbolt and carefully detach the sterndrive from the transom assembly.
  3. Access the Bellows: Locate the old U-joint bellows connected between the bell housing and the transom plate.
  4. Remove Old Bellows: Loosen and remove the stainless-steel clamps securing the old bellows at both ends.
  5. Clean Surfaces: Thoroughly clean the mounting surfaces on the bell housing and transom to ensure a proper seal.
  6. Install New Bellows: Position the new bellows, ensuring it is correctly oriented and seated.
  7. Secure Clamps: Install and tighten the new stainless-steel clamps to create a watertight seal. Do not overtighten.
  8. Reinstall Drive: Carefully reinstall the sterndrive, ensuring all connections are properly aligned and torqued to manufacturer specifications.
  9. Final Check: Lower the drive and check for leaks or binding before reconnecting the battery.

Troubleshooting & FAQ

How do I know if this bellows kit will fit my sterndrive?
This kit fits OMC Cobra Sterndrive models from 1986-1993 and a range of Volvo Penta SX and DP series drives. The best way to confirm fitment is to match your existing part number to one of the OEM cross-references listed: OMC (911826, 3841481, 3850426) or Volvo Penta (3854127, 22197130).

What are the signs that my U-joint bellows needs to be replaced?
Common signs of failure include visible cracks, tears, or perishing of the rubber. The most critical symptom is water entering the bellows, which can lead to catastrophic U-joint and gimbal bearing failure. Regular inspection during maintenance is crucial.

How often should a sterndrive bellows be replaced?
As a preventative maintenance item, U-joint bellows are typically replaced every 1-2 seasons, especially for boats used in saltwater. Always replace them if you notice any signs of wear, damage, or water intrusion, regardless of age.

Nice Idea But Won't Last With A Frenchie
Color: orange & blue, Color: orange & blue
My dogs loved the balls, however, withing 30 minutes, they were in pieces. Be careful because these parts can become choking hazards. Maybe they should try to make them a bit more sturdy, then I would buy again. Wish I could give them more stars because I liked them and the dogs did too.

Fits Cats not Dog size
Color: red&green
Sure these balls are cute, but most definitely not a dog size. I wouldn’t waste your money, unless you own a cat!

Not durable
Color: red&green
The description says for cats and dogs. My 6lb mini poodle tore it up in less than 40 minutes. The red one worked but the green one wouldnt even turn on. The indicator said it was fully charged but u plugged it in for a short time but nothing. I dont know if i can get a refund or not since the cover on the red one has been completely torn off. I dont recommend this product
