Hello Joern, I am just heading to Europe for the week so i will need to check when I return next Sunday. Yes I would consider trading 2 sets for 2 engines.
The "hot pipe" was a nickname for the Quickdraw tuned pipe they sold with their engines. It has since become one of the best pipes for gas motors. Compared to other early gas pipes, the QD pipe was produced in steel compared to aluminum.
I don't like them! There are a pain to configure especially in a 2P boat. They add extra wire. They add resistance and another failure point. What you have pictured might work for a 75A setup, but try that on a 350A setup with twin batteries.
Understood James,
I do not have many spare parts for it. I am running mine in a 20 year old Road Runner clone which is well paired for the power of the OS.

For anyone that does not have their own printer but does have files, Treatstock is an excellent resource. You can upload STL files, choose quantity, material, infill, colors, etc and then have multiple vendors/individuals quote the parts. I have ordered over 2 dozen different parts off...
The last motor with the square head is an older JG motor. Probably a 23cc version. They were good motors 15 years ago, but they have been superseded by the latest crop of 26's, 29's and larger motors.
