Location: Cedarburg, Wisconsin | Just was wondering if anybody could explain this to me. I always enjoy learning new things and am hoping somone out there, a lot smarter than I am on the subject, can give some good advice how props are designed and described.
I see some props are said to have good bow lift, some good stern lift, and other various qualities. What causes the lift to mainly the bow vs. the stern? Is it the pitch, the rake, the diameter, the number of blades or something else?
If you are talking about a hole shot, obviously the motor has to be able to rev up in a hurry to be effective, but if there is too much venting it just loses bite completely. To get better bite as I understand it, you can either go with less venting, a larger diameter or more blades from what I've read. What is the advantage of larger diameter verses more blades if they both do the same thing?
You see prop choices with solid through hub exhaust, with vent holes or over and through hub exhaust. Obviously that is to control the amount of venting for better hole shots, but is there an advantage to one method of venting over the others?
