If a speedboat has a motor that goes below the boat into the water, then shouldn't that motor produce a torque on the boat?
Shouldn't that torque cause the bow of the boat to rise? And the faster it goes, the more likely it will flip?

Google "angle of attack" and "resultant force."

Prop force vector (3D) is but one total force there are: hull water drag, hydrodynamic lift on planing surface, air drag and lift topside and below, gravity vector. All can be in or out of balance at steady top speed and while accelerating. In the outboard hydros I run there is a sensitive balance to keep it right side up. Hull design is a great part of success of force management.
