sciencetoymaker has a full step by step tutorial series on putt putt (pop pop) boats starting in January 2009 with episode 1 here https://ai-tube.com/videoai/2MS0zwehNkZ
Here is a good video on tweaking the speed of these boats https://ai-tube.com/videoai/C2foFX79r4t
This link that explains the general annealing process without getting too technical http://steamshed.com/annealing%20process.html and here is a YouTube video on the subject by George Goehl https://ai-tube.com/videoai/3wFm11ym8ZN

Some history on Pop Pop boats you look at this Wikipedia link on the subject http://en.wikipedia.org/wiki/Pop_pop_boat they have been around since at least 1891 when a patent was filed by a Frenchman named Thomas Piot.

HOW DOES IT WORK?
Water in the boiler is turned to steam. The steam has a greater volume than the water so it pushes out of the boiler and down the tube. In the tube it cools, condenses and contracts so it is drawn back into the boiler and the process repeats. The action of the steam pushing into the tube pushes the existing water in the tube out the back and that drives the boat forwards. When the steam cools it condenses and contracts so the external pressure pushes the water back up the tube.
If your next question is "why doesn't the boat oscillate backwards and forwards due to this push-pull effect?" try blowing a candle out and then try sucking a candle out and you will see the blow is fairly directional but the suck is not.

Seems to work ok 🙂. 48 h curing time is a drawback, but its cheaper than epoxy. Will try to fold a motor like this one👍

most of the videos show that type boiler sitting at more of an angle. Permatex makes a high heat silicone for automotive engine applications, it runs around $6us and is good for around 600-700f,

Nice job ! 👍

The sealant seems to be holding out well. I think it works great. Maybe a change in the boiler shape (due to the heat) made it go quiet? Got a little rhythm going there at 7:14.
I noticed it picked up speed when it went quiet and found that odd. Great video. :D
I think I mentioned but there is a high-temperature silicone sealant you can buy. I think this is the one I used when I built my Stirling engine.

In this video I will show the electrolysis rust removal process. It's simple and very efficient way to remove light or heavy rust. Anyone can do this without spending money on rust removal products.
