You Checking Our Props????

Re: Blades on propellors
 

Yeah... in a way I'm checking out props.... seems most people have either a four or a three blade prop... mostly bravo style.... :eureka:

Re: Blades on propellors
 

The Cig is running 4 blade 28 x 15.25 labbed on Bravos. 600HP SC'd 80+.

The Cat is running Arnesons and what is pic'd below:

Re: Blades on propellors

Re: Blades on propellors
 

I changed from three blade Mirage's to four blade Bravo's this year.
TRS drives.

Re: Blades on propellors
 

If, I counted all the blades on my propellers I would still be counting. :drink: :crazy:

Re: Blades on propellors
 

I just received a new pair of stock Bravos to replace my labbed ones. I want that 5 mph of cruise speed back. With these gas prices, I could care less about one or two mph at WOT!

Re: Blades on propellors
 

I have a 26' Nova ST (28' LOA) with Mercury 350 Magnums. I like the Turbo Hydromotive "Bravo" props on my Alpha drives as they have a wider diameter and more blade surface area and go with a 21 Pitch for power coming out and a nice cruise. These props a quite cupped and dig in nicely. A 23 pitch would buy me only 2 mph more and then the hole shot suffers and more wear on the drives. I tried a 4-blade and liked the 3-blade for my application better. I see more and more big blocks going to 4 blades. I was going to go bigger this year but this thing is so efficient on gas and in such good shape I am hanging onto it. If I remember correctly 3000 RPM is right before the secondaries open up and cruise is around 48 mph. It's not the fastest ride but soild and cheap to keep till retirement and a Top Gun.

OE prop is a 26p $ Blade Bravo 1....tweaked!!!

Just got my new Hydromotive QIV X from Julie :drool: from Throttle Up!! Didn't get a chance to try it out this weekend, soon though.....like Wednesday!! :)

Re: Blades on propellors
 

Reed, they are Rollas.

Re: Blades on propellors
 

It is curious to see that 29.33% are running something other than Bravo I drives. It would be interesting to see a breakdown.

Thank you for the poll Reed!

I have 2 x 3 on my Black Hawk drive. Does that count as 6? ;)

Re: Blades on propellors
 

Hows that Black Hawk holding up? What boat is it on?

Re: Blades on propellors
 

31 Pitch 3 Blades #3 SSM Large Shafts.6000 RPM prop speed.

Re: Blades on propellors
 

Run a 4 blade now, but interested in trying a 3 blade "Accelerator" to compare. I have a Mirage Plus that is a spare that I might convert.

Re: Blades on propellors
 

Acclerator,I currently do not have one in stock,They have been going like hotcakes. :D maybe someone will let you try theres ,there are hundreds out now.let me know if you want a new one or just convert if you just hate the prop will credit you towards another style prop.But I bet you will like it.

Re: Blades on propellors
 

So far so good. About 60 hrs of beat the crap out of it running. Its on a 25 Daytona with a 500 efi.

Re: Blades on propellors
 

How are the Merc 5 blades in comparison to say Herring or Rolla with #6 drive applications. Price and Speed, Acceleration, etc.

Re: Blades on propellors
 

I am running 30 pitch Bravo 1 four blades. I plan on trying some better props after the end of the summer.

Re: Blades on propellors
 

Running Hydromotive Quad IV's......

This thread has been dead for 6 weeks... suddenly "it's alive"........ :D

Re: Blades on propellors
 

to keep with the topic we run 4,5,and 6 blades on our svl . race boat.
the 6 blades out accelerate everything else in our testing . but we have found that this changes with the prop height ( X - dimension) on a pleasure boat with a deep X the less blades that you can still get on plane will normally be faster however if you start lifting the drive height the slippage will go through the roof so if you add blades you can go higher and the net result is a gain ( you seem to gain more from lifting the drive to reduce drag than you lose from increased slippage and as I said the 5 and 6 blades take care o;f that)

I normally have the girlfriend swim with a rope tied to the boat and her.

Re: Blades on propellors
 

Where you bored or what? :D This thread was at peace, resting for 16 months. :D

Re: Blades on propellors
 

Why are all these people running 3 blades?

Re: Blades on propellors
 

post 29 pic

Very agressive looking and some what prehistoric... :D

Re: Blades on propellors
 

I can't imaging running 3 blades on anything anymore. I remember when everyone was skeptical about going to 4 blades, now 4 blades are so common and even 5 blades are making a big push. I just made the switch last year to 5 blades, not sure if I'm ready for sixers anytime soon... :D
