FSD brushless motors are good, ball rearings are better than other chinese motors Very good for the price,

To be good I wound recommend other better motors for FAST electric boat. I personally decided to stay away from them for I and my buddies have fried at least six of them, in boats and trucks. Main problems include rotor demagnet due to low efficiency and cheap magnet material, and rotor split apart even at medium speeds. They are VERY cheap but like the old saying you get what you pay for. They might work well if you use it leaving enough margin, e.g. use a 36-74 as a 36-60, in a boat under 65cm(25").

See why Steve stopped carrying the KB45 motors, they are similar products.

FSD are low cost brushless motors like KEDA, Feigao, KD, Nemesis, Medusa and others.
Mega and Neu brushless motors, midrange price/quality
And if you want the best have a look to Lehner, Hacker and Plettenberg
