## ⚙️ Key Features

-   Marine Propulsion group
-   22.680 kg - a heavy freight item
-   Supersedes 3858260
-   For 4 DP drive applications

## 🔌 Function

Encloses and supports the gear set and its bearings, holding them in the alignment the gears need and retaining the oil around them.

## ⚠️ Common Signs of Failure

-   Oil weeping or dripping from the housing joints or seal bores
-   Water in the drive oil, showing as a grey or milky sample
-   Gear noise that will not tune out on shims because the bores have moved
-   Cracks or impact damage after grounding or a strike
-   Bearing bores worn oval, letting the outer races turn

## 🛠️ Service Notes

-   At 22.68 kg this is a two-person lift and a freight item, so plan handling and delivery before ordering
-   Transfer the shim and bearing settings carefully - a new housing needs the stack measured and set again rather than copied
-   Renew every seal, o-ring and gasket that comes off the old housing
