## ⚙️ Key Features

-   Marine Propulsion group
-   0.195 kg
-   37 applications across D and HS installations

## 🔌 Function

Transmits drive through a toothed engagement, turning the chain or belt it runs with rather than relying on friction.

## ⚠️ Common Signs of Failure

-   Rattle or slap that follows engine speed
-   Teeth hooked, pointed or worn to a thin section
-   Chain or belt riding badly or jumping under load
-   Debris and bright wear dust around the sprocket
-   Timing or engagement drifting out of position

## 🛠️ Service Notes

-   Sprocket wheel 3843041 at 0.18 kg and 3843686 at 0.563 kg are the other sprockets in this batch, so check the fitment and tooth count rather than ordering by name
-   Renew the chain or belt at the same time, as a worn pair destroys a new part quickly
