Flushing a marine engine

[andythefiddler]

As I get used to maintaining PADME myself I am today wondering - When was the last time her coolant (raw water) system was flushed?

She’s about 12 and it should probably be done.

What additives to clear the waterways?

How to manage the task?

That’s all really - still so much to learn!

Rydlyme is the stuff to use but it needs to be circulated with a small pump.
