This isn’t extremely fast when compared to some other propellers – there is more of a focus on torque and power in order to push a massive ship through the water. Remember that these propellers are in the ocean, not in the open air.

WebThe propeller revolution rate is the engine rpm divided by the gear ratio. This propeller rpm times the prop pitch determines the theoretical distance that the boat should have moved in one minute, which can be converted to a theoretical boat speed in miles per hour. Due to prop slip the boat is actually going slower than the theoretical speed.
