Re: Runaway Boat in Half Moon Bay

As PHIL notes, propeller torque from a right-hand rotation propeller on an outboard engine will tend to put the boat into a right turn if the steering system does not resist such movement. In the recording, the engine speed appears to be set rather high, so one could presume that at the moment the c...

Re: 170 DAUNTLESS, 100-HP; Propeller

Four-blade propellers tend to have more blade area than three-blade propellers, causing them to create a higher load on the engine trying to turn them than would be created by a three-blade of similar diameter and pitch.
