Reply To: What size propellers??

Hi pastasimon,

I agree with you that race boats routinely lock their blades (typically 2 bladers)….but from what I recall they mark the shaft such that the blades are aligned with the back of the keel thus minimising turbulence/resistence to a minimum?

The reason why I'm placing the motors in reverse (remember – I'm running with hydraulics so I'm actualy changing the direction of flow of the hydraulic oil at the proportional valve) is because if left in forward the shafts just spin at silly speeds …as they do if left in neutral. In reverse there appears to be enough resistence in the system to stop the spinning…..but her speed is affected as outlined earlier.
