Likwid!! You being a person with extreme knowledge, can you please explain why you need to change the prop to get down to 1 or 1-1/2 knots????
With my boat in neutral I do approx. 2.5knots just drifting!!!
Knowing what you know about props can you tell me where I could find a prop that will free spin in reverse when I have my boat in neutral !!! By free spinning in neutral will it slow my boat????
