Pw With Bme 50
The BME 50 and the Taurus3.2 are VERY VERY similar powerplants. I had both of them and used the exact same props on both of them (the both have the 7/16 prop shaft) and they turned the same prop at the same rpm.
I even used a MENS S 19x10 3 blade. I got very good performance with this prop...it turned around 6600 rpm
