Hydro 5 Blade
 

Anyone running one? I am running Bravo 32's now and getting way too much stern lift, I run faster the more weight and the deeper I bury the stern. Currently running Imco SC with -2" lowers. Runs 95 MPH at 5600 17.7% slip. My prop folks are telling me that we could certainly massage my current props but I may want to consider the Hydro 5 blades, that Hydromotive is working hard to get into that space and will do a lot of work with you. I also cavitate getting on plane playing with throttles until it comes over so for the 3 blade folks I don't think I can find a 3 blade that will work.

My experience is that the P5X is somewhat similar to a B1 prop but less slip (on a 75mph Fountain 27).
Guessing that the P5 will provide more stern lift.

Stern lift is what I'm trying to avoid. I'm needing something to carry the bow more. Thank you !

The increased blade surface area of 5 blades will increase stern lift.

Maybe try 1" drive spacers??

That is an option, also the Quad IV-X was the prop I was told about and I misunderstood when I said 5 blade. My goal is to get it to carry the bow more, I'm obviously getting too much stern lift and the bow is digging. I'm running 95 and it's not that it is uncomfortable I just know it's not 100% correct.

The Hydro Quad IV-X is pretty similar to Bravos. They are more true to actual pitch and you'd want to drop 1" to maintain the same rpm

Do they carry the bow more without as much stern lift?

Are you sure your stern lift problem is due to the prop. I have a hard time seeing a Bravo prop is creating too much stern lift. Maybe your drive is too high and drive itself is trying to surf the wake. Also your description says, "the faster I run the deeper I bury the stern". If that is indeed happening, you need stern LIFT.

I think it is best to give up some basic info. What Make, model, length is your boat? Where is your prop shaft in relation to your hull. Are you 2,3,4" below it?

Have you tried calling Hydromotive? Sounds like they're pretty good to work with. I know on their 4 blades they do a good job on lifting the stern sinus be skeptical about a 5 blade helping you just because of that. Is think you be better off with a different style or reducing blade count if you want the nose down more. Just some things I've read around here is all so take it for what it's worth. But definitely recommend just calling them up and seeing what they say.

What I was saying is it runs faster with more weight because the stern is deeper and is getting more bow lift. At WOT it seems to I would not say bury the bow but definitely dig a bit. I did go to -2" shorties and the boat does like them with this exception. It feels as though if I could get more bow lift it would be ideal. I am within 100 Rpm of what my builder would call ideal.

It's a Saber 28 Cyclone. Running Imco SC WITH -2" lowers. It is possible I may have to put a space and set the drive deeper. I am honestly not exactly sure how deep I am I am going to say about 2 below the stern. Runs 95 at 5600 with the 32s. It does cavitate a bit coming on plane but is awesome as soon as it comes over and it jumps on plane. Went from 10% Slip with standard length to 17.7 slip now. I'm making more RPM now and picked up 2-3 MPH especially when heavy.

If your within 100 RPM of ideal RPM, then I would send those 32's out to be labbed and add a little cup to them for bow lift. From what you posted that's my thoughts. Bblades and FJ propeller both do great work. FJ Propeller just worked a set of Maximus props for me and they were in contact with me as soon as they arrived. Also had them back within about a week from when they called me.

Thank you all for your answers!

I have a hydro P5X that I sent for labbing. Running a labbed bravo1fs also.

The p5x was some of the WORST new props my lab-guy had seen, and that guy is a known, serious professional with props here in sweden.

Fun to have paid a decent amount of Cash for a prop that was uneven, unbalanced and too thin on 2 blades near the hub.

Havent ran it after labbing, but before I lost 2 knots compared to the bravo, but the grip is awesome. And real smooth ride.

This is interesting that you say that. I have had excellent luck with Hydromotive. I'll go so far as to say they have out performed Mercury props on every boat I have ever put them on including custom labbed Maximus props, that is just me and the boats I have used them on. With the said, I tried to order new Hydromotive props a few years ago and everything was out of stock because they were moving to a new foundry. Maybe or old casting location was letting production quality slide. I have a new set of P5X 35s I plan on using this year, so I'll soon see if they are as good other hydros I've used in the past.

Who is your prop guy? Niklas Mohel?

Yes, correct :)

I typically use Airmarine in Chicago, never let me down, they are certainly going to look at my 32 simply mentioned that Hydro has been interesting to work with lately and done some interesting things custom order.

Was the prop new direct from Hydromotive?

Yes, but i bought it thru a store, not in stock tough so I had to wait to get it made/shipped from factory.

although, I want to add that he advised me to buy a hydro because of their quality, so he was pretty shocked how bad it was..

I've never ran the QIV-X's to compare, so can't say for sure.

Based on the increased slip and less bow lift, I think you'd do well to try some 1" spacers. Another thing to try is to have your props labbed with more rake and cupping.

Hydrommotive 5 blade with cut barrel might do the trick

I have the same issues with my labbed B1 30P. Causes more chine walk and needs a lot more trim. I have an older Hydro QIV that picks the bow way up over the B1 but it doesn't bite as well getting on plane. The B1 is way better for cruising but the Hydro is way better for top end. I can break both props loose easily even after I hit 30mph. I don't know how the air tubes work, if my Hydro prop breaks loose at all below 35, I have to stop to get it to bite again. I am hoping to try a Cutting Edge 5 blade this summer, I'm looking for the same thing.

Thanks for the info, my 32's break loose when getting on plane but I can back off and they are fine once it comes over. If I carried the bow more I think that will more top end without all the weight. And hopefully without spacers, it's cheaper that way. Lol Just means it won't work nothing usually fixes a boat problem inexpensive.

For those who have commented and following. My prop guy says the big difference in the Hydro's and bow lift is much more rake than the Bravo's. I will post as we determine with results.

our set ups are similar as you know. only real difference is i'm 1.36 ratio . i'm running about the same 95mph with a set of hill propellers.

ido not feel any bow digging and if i get crazy with trim ( 8 or 9 on the indicators) my bow gets real light.

have you checked the bottom of the boat?

mine also spins the props getting on plane, actually i just give it more gas and kind of do a burn out till the bow starts to settle down.

I don't remember is you have shorties, I do have -2".
If I trim much over 6 I start to lose speed, I did have your situation with standard length, in fact it loved to go airborn. Sounds fun but not really! Doesn't do that at all now. Regardless of trim I don't even throw a rooster at all. I have not checked the bottom.

I do the same kick it up to push it over and back down a bit.

yes, mine has -2 imco shorties.
