mcr, that is a very nice engine. Your have every reason to be a proud builder. So how long is the launch? I'm guessing 5 feet. Very nice work and thanks for showing the video.

I have had a rather unpleasant experience with Ebay, when I had a close look at the boiler I purchased for the boat it turned out to be soft soldered and then sprayed to cover up the fact.
I had little choice but to cut it up and use the copper to make a new boiler.
With lots of help from a fellow club mate this is the result so far.
