Keep in mind boats have active cooling. People had great success with kb45's in boats, I burnt mine up in 10 mins in an e-maxx

So an eight pole may be limited to a small max rpm value depending on the esc.
every esc has an rpm limit. A 100,000 rpm limit on 2 poles will be 50,000 limit for 4 poles and 25000 for 8 poles and so on..................
