what is the difference between a 2 pole and 4 pole ... Number of poles is probably only a minor consideration, better to look at Kv and torque needed (determined by size of boat). I'm not an FE guy but I believe most of the motors used are 2 pole motors, they calculate on spinning the prop at 30 000 to 35 000 Rpm and match voltage to Kv to achieve that figure.
