🔌 Function

The kit changes the required mechanical and connection components so an approved engine and sterndrive combination can be installed in the later factory configuration.

⚠️ Common Signs of Failure

• Repower components do not align with the existing drive
• Existing installation does not meet the later factory specification
• Required adapter or connection parts are missing
• Drive or engine generation is being changed
• A Volvo Penta conversion instruction specifies kit 21121705

🛠️ 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
