. I have been told that it is a bad idea to install a bow thruster that is too powerful.
True, don’t install a 50 hp bow thruster.
Seriously, a powerful thruster probably won’t hurt you, but it will be more expensive and not necessary.
You run a thruster by “blipping” the joy stick, not by running it continuously : Strong bow thruster, use less, weak thruster, use more.
Most bow thrusters are limited by time of operation, usually 3 to 5 minutes continuously, or every hour, go beyond that and then they overheat and go to hell.
(No cooling down there in the bow)
Again, if you have strong prop walk and a big rudder, don’t bother getting a bow thruster, get expensive girl friends and strong drinks instead.
