Re: trouble matching best prop
Im sure no expert but I would think a 21 footer getting 60 mph would be pretty darn good.<br /> As I understand it a 4 blade helps hole shot and<br /> load pushing not top end. I read an artical the other day that the most efficient design is a 2 blade and next a 3 blade.Most of the props you see<br />are 3 blade so it would seem they must give the best overall performance.<br /> If you are looking for speed only, surf a little<br />bit using key words like outboard speed prop,<br />and such. Just keep in mind a high speed prop <br />will lack hole shot and load pushing ability.<br />There is a prop called the torque shift you can<br />see it at
www.land-and-see.com/marine/torque-shift<br /> there is a pretty amazing video.Ive heard it has<br />problems in dirty water and it is very pricey.<br /> but has termendous hole shot with excellent top end! It actually shifts.
