Engine braking on marine engines would not be useful, there is no DIRECT transmission to a solid material. The water passing a "stalled" propellor, or one turning significantly slower than the speed required for negligible drag, provides similar retardation to the craft, but not much torque on the engine crankshaft. As there is a fluid medium involved, there is no "engine braking" involved, or possible.
The only means of increasing the drag, is to reverse the rotation of the prop to push water forwards.
I hope that this explanation is comprehensible.
