Heat and damp are ideal for drying out sintered metal bearings.
If I wrote otherwise my mistake--My fan will draw outside air IN through the main window and door galleries from outside and blow that cooler air in over the boiler area below and aft- creating positive pressure inside the hull.
So all is as I think you are recommending.
Once again not a high speed blower -air exchange and cooling are the goals. The boat has been run on steam prior to my ownership and was not fan ventilated to my knowledge. My superstructure is wood and metal and I have it sheathed underneath with light aluminium sheet .
So hopefully I will be improving the engine room temps!
P.S. Hookpilot My little fan is 70mm square
Nice Tug George!
Nice tank Gary!
