## ⚠️ Common Signs of Failure

-   Low drive-oil pressure
-   Repeated oil-pump or filter faults
-   Original components are obsolete
-   Metal contamination in the drive
-   Volvo service instruction specifies the conversion

## 🛠️ Service Notes

-   Check the kit contents against its parts list before starting and read the instruction sheet supplied with it through to the end — a conversion is a sequence of steps, not a like-for-like swap
-   Confirm the kit is the one for your engine or drive serial number before any of it is fitted; conversion kits are tied to build ranges rather than to a model name
-   Expect to renew the gaskets, seals and single-use fasteners that the work disturbs, and to have the fluids and consumables for the affected system on hand before you begin
-   Record the conversion against the engine or drive serial number and keep the paperwork with the boat, so later parts ordering and diagnostics reflect what is actually fitted
