billie, I repeat, hp IS thrust ****multiplied*** by rpm times a factor.
Remember that, that is not going to change withing your lifetime.

No Horsepower is Thrust thru a distance. It is also Torque multiplied by RPM
times a factor.

But in the subject case you should look at the Usable HP and Thrust in your
application. Just because a motor is rated 15HP at some RPM does not mean
you can actually use it at 15HP in your application.
