Hello again
I no I have been asking alot of questions lately but I'm trying to take in and learn the nolige from you guys who have been doing this for years,
I have been looking at jet drives again I have one but I keep blowing the impeller well to be honest I have decided to make my own one out of some plumbing pipes my question is will just a normal prop work? But I need a prop smaller than 20mm anyone no where I can find one thinking running a m2 shaft through it but dunno where to find that small size of prop

tried jets before out of pipe. the results were pathetic i hope you have better ones than i did.

as far as small props go for a 2mm shaft i used this:

the prop is push fit and about 18mm in diameter. in fact i bought a couple of these a built a few small rc boats with imo great results. You might be able to source some cheaper ones but i new exactly what propeller i wanted and this was the only way i new how to source them as you can buy these props off the shelf.
