Hi people,

I need some help to buy a brushless motor.
I will build a boat with JetDrives and I'm thinking use one of these:

I want to choose the most powerful engine that JetDrive can handle.

Any idea?

Something like this?

That motor on 7.4v lipo would turn about 29500 rpm. That would be right in the range of what is called for to run this drive. What kind of a hull are you planning to put it into? Would love to see pictures of it if you have any or of it when you build it. Good luck!

This Drive is rated for 20000 rpm, so a B28-57-15L 1900kv 750watts on 3s is 21090rpm and on 4s is 28120rpm.
