I'd love to find a Blackhawk for my Sweet 16, but they are pretty rare and often too $ for what they are.

the blackhawk has a High X, according to Merc it need to be a minimum 2.5 inches above a standard bravo.

My nomenclature was wrong last night it was late when I was typing. Thank you for correcting me.

My brain had me wanting to say say a low center of gravity for engine placement due to the higher X-Dimension that was possible, sometimes the words in my brain come faster than my typing ability....not a low X-Dimension....that is just plain stupid on my behalf....at least it is a typo on something that is not critical in someone's life, but when I have typo on a motion or brief and don't catch it, than there is hell to pay. I need to hire you for my proofreader, you do an excellent job!

All that stuff Mercury put in that guide and they could have just said the bottom of the bullet needs to be no lower than the bottom of the hull. mercurys standard recommendation places the prop 8.25 deep the drive is 8.25 shorter than a Bravo, plus they want the X dimension 2.5 higher, The bullet has a 5" diameter so half is 2.5".

Btw an aeration tubes (like ones some run on some #6 and arneson drives) many times solve most of the issues associated with this drive. Helps plane off time, slows Idles speed, takes load off of the shifts, takes load off the drive when in the rough, when suddenly the props are monetarily submerged. When the props are surfacing the tube is just along for the ride but when tops of the blades are below the surface it allows props to pull air and across them and reduce load, and keep slip numbers more consistent. (when on plane/props surfacing they tend to have high slip numbers, but when submerged the are extremely low, this the root cause of alot of the issues.)

I had seen a few builds before where the tubes were added like that.

I appreciate the offer but I agreed to sell them to the first guy that asked. I actually have two $800.00 offers, so if the first guy does not have the cash it is not a problem. The first guy is local, so I do not have to ship the props. I believe that when he looks at them he will buy the props. I will let you know if the props become available.

Thanks.

Can a guy get 31p props for the Blackhawk?

Some boats benefit from two different pitches. Run two different pitch props.

Can you give an example which pitch front and back and what boat?:confused:

You will need all 3 sets X2 to do this research. 27, 29, 31 for each drive. A $3k research if you could find all 3 pitches.

Example 27/31, 29/31 etc...

That's awesome. How much are those and how much HP are they rated for?

I don't know, I could not find the specs, I would call Weismann and ask them, that is a very good question, the webpage has this written, whcih I can infer it can handle a large amount of torque since the sentence references both turbine and diesel:

"Designed by Patrick Weismann to withstand diesel, turbine and gasoline power and torque, his 3rd SPSD drive goes to the next level aimed squarely improving efficiency in the single engine / drive mark" from the website.

We have 4 for our Donzi 22 LE Blackhawk. 3 are blown lol
