## 🔌 Function

Seals a transom joint by being squeezed into its groove, keeping water out of the boat.

## ⚠️ Common Signs of Failure

-   Water tracking into the boat around the transom assembly
-   Damp bilge with no other obvious source
-   O-ring flattened, nibbled or with a permanent set
-   Rubber hardened, cracked or swollen

## 🛠️ Service Notes

-   O-ring 3852535 is also a 13.6 g transom seal kit o-ring on the same 20 TSK applications - nothing in the published detail separates the two, so take the number from the illustration rather than trying to tell them apart
-   A transom seal leak lets water into the boat, so if the drive is off, fit the whole transom seal kit rather than a single ring
