## 🛠️ Service Notes

-   At nearly 90 kg this is a lifting job - arrange the hoist and the support before starting
-   Check the drive oil condition, the bellows and the seals before committing to a complete unit
-   Confirm the lower unit's ratio in the boat, since the upper unit is used with both the 1.69:1 and the 1.85:1 lower
