## ⚠️ Common Signs of Failure

-   Whine or howl from the lower unit that rises with load
-   Bright flake or paste in the drained gear oil
-   Clunk or heavy backlash on taking up drive
-   Teeth pitted, chipped or spalled on strip-down
-   Bearing races blued or scored from oil starvation

## 🛠️ Service Notes

-   This one number serves two ratios, so confirm the drive's own ratio marking rather than assuming one gear per ratio
-   3857099 is the 1.78:1 gear and 3857155 the 1.68:1, and the three are within 4 kg of each other, so weight is no guide
