• Bonjour,
  
  Objective: Install a steam plantin a model of a coaster freighter on a 1/100° scale initially powered by an electric motor.
  This conversion is the prelude to the same operation that I am planning for a Dean's Marine Liberty ship kit in ABS at 1/96° scale :

• Very ambitious and a little scary too!

• Bonjour,
  
  I feel confident with this "large" wooden boat, I have to confess that the Liberty ship project will be much more difficult because of a lot of details and a lack of access in a hull made of ABS furthermore...
  
  But steam Liberty ships are so rare, I like taking on this future challenge

• Yes, it is the ABS combined with a flame fire boiler that I find to be truly scary!
  
  But Raphael, with your vast experience and knowledge, I truly believe that if it can be done, it is you who can do it!!!

• That engine seems to set up a rather serious vibration. Perhaps that is just because it is not firmly mounted.
  
  Looks like it should prove to be a capable powerplant for a marine application!

• Bonjour,
  You are absolutely right, during this test, it was not attached to anything and ran it quite too fast.
  Usually, I like coupling my 7,5+ cm3 (ot is 8,5 cm3) to 3.5" 4 blades propellers and the one installed is just 2.5" so there won't be much effort even with the coupled pump and I will be able to operate a 30 PSI working pressure as I like and set my gas regulatirs.
  Furthermore, at this pressure, the steam is saturated and self-lubricating.

• Looks like it all fits in there rather well.
  
  Does this project help inform how you will manage to steam power the Liberty ship you have waiting in the wings?

• Bonjour Stoker,
  Absolutely and it will be quite mote difficult to steam because the liberty ship kit is quite different, not conceived at all for steam and made of ABS.
  I have already choosen a smaller steam plant but the maon difficulty will be to tighten the plumbing elements, especially the gas part, because I have already had to deal with leaks and each time I have to dismantle everything in a certain order, reassemble then tighten, which also led to cutting a pipe in two to be able to install it.
  For example, to save room and a servo, as it is not a fast boat, I have choosen a Microcosm 4,71 cm3 M2B machine:

  A small boiler will possibly mean pump... electric...

  But let's finish the Bavaria project first !
