anybody need a 27" P5-X
 

Hi Guys,
There is a barely used 27" Throttle UP blueprinted P5-X in the prop classifieds for sale very reasonable ($775, I've got $1500 in mine:eek: ).
If you have a late model (2000+) step bottom Heat, this is a great deal, if the pitch is correct for you.
Wish it was a 29", it would be sold (to me:rolleyes: ).
I know the seller, and it's as new.
Regards,
Steve

28 heat prop question
 

Steve,
I have attached some information on various props I have tried. The boat has a HP 525 Any suggestions on eliminating the excessive slip? The drive was lowered 1 inch from the factory.

I saw the add for the PX-5. I'am thinking about it. Need to unload a lab bravo 1 28 frist.

Bill,
Sounds like someone out there in Havasu is listening if you got them to got to 18 1/4"s XD. You may want to check that to make sure. BTW, my XD is 19 1/4"s, and I have added a 1" spacer taking mine to 18 1/4"s effective XD.
It looks like the Power Tech 5 blade is getting you into the direction you want. Your slip #s are better across the board, and within 1.7 MPH of the 26" B1, which is on the limiter (I think) @ 5250.
I'm not familiar with the Power Tech. Are the blades straight (like a cleaver) on the trailing edge, or do they have a radius, like a round ear? If they are straight, it's a stern lifter like the Hydro P-5, not what you want. Rounded trailing edge props like the newer P-5X are bow lifters, and what the Heat needs.
If the PT is a bow lifting design, blueprinting it to your hull (thinning, balancing, cupping) will get you back to 70+ easily.
You can generally expect 200 RPM from a good blueprint, with much better slip #s.
If you can get your hands on a 26" Hydromotive P5-X (they have an exchange/test program), I think you'll be pleased. The 27" for sale here is such a great deal you might want to buy it. The Throttle UP blueprint on these props has been the $hit on our boats. It may be possible (I would ask Matt) to repitch it if it's too "tall".
Let us know how it goes. Pretty boat. Are you coming to the Jamboree?
Regards,
Steve

Steve How does the pitch rating on the P-5X compair to the bravo 1. In other words P-5X 27 would be about what pitch in bravo 1?

Steve another question. Are you able to change the hubs on P-5X. I have the bravo XR drive.

My 28" P5-X (true pitch) turns almost the exact same Rs as a 30" B1. So, the 27" would be similar to a modified 29" B1.
I also have an XR shaft, and the P5-X does takes the Mercury style hub inserts.

Steve

Thanks alot for the info. P-5X 27 would be a little to much prop. I need more HP!

I have a 2005 Heat and i am turning a stock 26P 4 Blade B1 Prop...My RPM`s are around the 4950 mark....I am in the market for a new prop.....Sounds like some of you guys know your props.....Whatcha think I should go with???

BTW my Heat came with the 496 HO ...After 1st season I had bob at FTM do the Raylar install on mine....I also have the 1 inch spacer in mine.........I have one time under perfect condition GPS`s mine at 75.9 MPH......

Bent,
Those are great #s for a stock 26". What is the rev limit on your motor? If you can turn it up a little more, say 5150/5250, I think I would have the 26" blueprinted to your boat, which should give you another 200 RPMs, and a few MPH.
You could also try a 24" or 25" Hydromotive P5-X (they have a test/exchange program), and you'll be pleased with that prop.

Steve

The 25 P5X will turn about 50-100 RPM less than a 26 Bravo 1 prop. I ran those 2 props on my 28 Heat when it had a naturally aspirated 540. I could spin them to 5600 RPM around 75 MPH. The P5X ran great and really reduced prop slip. This was before I added a drive spacer.

Bent, your peak HP is at 5200 RPM. However, you are only down about 10 HP at 4950. I think labbing the 26 and then adding a slight amount of cup would do the trick. You must have the cup or you'll lose a lot of speed.

Steve,
I will have to verify the x-dimension. The only checking I have done is to measure from the bottom of the transom up to the outdrive. Mine is around 1 to 1 1/2 inches lower than the other 2 Heats in the area.
The power tech 5 blade looks similar to a B1 with the exception of more cup on the end of the blades. I have attached a picture of one. Since there is minimal slip, the power tech 5 blade is really sluggish out of the hole.
I plan to make it to the Jamboree.
Bill

I have a labbed 26 p5x on my 28 heat with a 500 efi. 1" spacer it runs 73.4 at 5100 to 5150. I will never go back to a 4 blade.

Bill,
That looks like a 5 blade Bravo one, not bad. It is definitely a bow lifter type prop.
I would have it blueprinted to your boat, and I am sure you'll be happy with it. Nice find.
Regards,
Steve
