Hi!..Ducky!
Lead is correct……..would have made really good sea going paint……….I can remember reading adverts for paint in the 50`s and it was always lead paint.
Latest position on GE……..Bearing housings glued inside hull….paddle shaft made……..all deck furniture finished and being weathered and abused every few hours……now working on deck planking and hatch covers
Got to think about the motors more seriously………if 540`s powered JD sufficiently……then 850`s should do the trick.
Still very happy building the great ship!
