Hi Otto and welcome to the forum.
First off we would like to see some photos of the boat, and also to know what make of steam pant has been fitted, as a starter.
Not that I am a steam man, but there are those out there and they will need to know what you have before offering advice.
Other details, like…fuel…meths or gas? engine additions…oiler, boiler pump….and so on
Good luck, Ashley
