Propeller Question

Can a 3 blade prop be as fast as a 2 blade on a V-drive cruiser?

I am guessing we are talking top speed? I have never ridden in a cruiser with a 2 blade, A sanger flatty with 2 blade, but that surely does not count. I always thought a good 3 blade from start to top end was all around the best bang. 4-5 mph difference?

Oh and I have no Idea what I am talking about:headscratch:

Yes I was talking about top speed. Let me add a little, I run a 2 blade, on occasion, on my 21 Howard ,with a blown 540, and it is 5/6 mph faster than my 3 blade. Of course it vibrates some at slower speeds. Also I have heard guys on here say that the "right" 3 blade could be as fast as a 2 blade. I am looking for information on the "right" 3 blade.

Don't think three ears would ever be faster on the top end, JMO it's getting from 45 to 85 where a 3 blade is worth the ride minus the 3 MPH loss on the top end. BTY I have a GREAT WILKS stainless 3 blade that would be great for your cruisier at Prime Marine Like new 300.00 takes it.

What size and for what size shaft is it? Do you think its sturdy enough for a blown deal?

15-5 Stainless is way stronger than welded steel.

just my 2 cents input. any application with H.P. over 600. A 3 blade can be dangerous and costly. see previous threads .

Can you elaborate?
