37 AVH prop slip
 

Question for you guys, finally had a chance to do a shake down run over the weekend and have a couple of questions. First being I am running the 32's that came with the boat, not sure of condition but seems like alot of prop slip getting it up on plane, is this normal ? What settings are you at when you get it out of the hole ? Second is do you get alot of feedback on the steering wheel, kind of like it wanting to center itself in a turn ? I am going to try a set of new stock 32's next week and see what the difference is, since I am not sure if these props have been adjusted or not. Any info would be appreciated.

I run in freshwater most of the time and mine didn't plane or handle well with the 4b 32s. They were fine in FL. in the saltwater. I'm running 28p 5b Maximus labbed by B-blades. Easy on plane and they carry the bow nice making the boat very predictable in a turn which is nice because I live on a winding narrow river.
My steering does the same thing if you just turn it a little. Roll it down over a quarter of a turn and it stays.

sounds good, I have a set of new 32's on the way and will get a hold of a set of the 5 blades as well and see which is best.

My stock 32's are fine coming out of the hole. I tried a set of Merc labbed 32's that were not. How many rpms did you see?

As Mark said, just roll it over 1/4 turn and she will come right around. Just DONT roll it much more than that! Made that mistake on Sunday while doing some more prop testing. Thank goodness she recovered...

Well if that is the case then these props are definitely toast, we ran it on sunday and could hardly get it up on plane, best thing that worked was to push it to about 3 K rpm and just wait it out, tried creeping it up as well as drives tucked in and planes down, but best was to leave the drives at about 2 with half tab, but still was slipping really bad. Once on plane it was ok but still feel alot of slip, so new stock 32's on the way and will retest this weekend.

But man this was my first time running it myself and WOW we loved the ride ! We had the standard lake erie chop of 3 foot mixed chop with 4-5 foot swells and we cut thru it like butter at 50 mph, glad i made the choice of A/T. Hopefully get all the small details worked out this week and get to run it a bit harder next time. Also starting to get a hang of turning it, just different than my PQ was.

Did you run the 15 1/2 or the 15 5/8 dia? I might try a set to see what the diff is from the new stock 32's.

Mine are 15 1/4

I will have to check with them, they only gave me the two other options. Thank-you

Lasz, leave the tabs all the way up when you get the new props. Putting them down causes more airation with the DDC hull.

Drives all the way in of course. Good luck.

The labbed 4 32's or the labbed 28 5 maximus 15 1/4 are the only way to go. Pat or BBlades can get you hooked up on the 5blade specs. The 5 blades handle twice a good and get on plane twice as good as the 4 blades. You will see pretty much the same speed across the board with either.

If you want an extra 3-4 mph go with a 30 herring. My boat ran 90.5 mph but getting on plane was no fun.

Sounds good, we will be trying the new stock 32's today as soon as the rain stops or tomorrow morning depending on weather, how much throttle are you giving it with the stock props ? The Maximus props sound like a great prop and might try as well.

I push them to 3000 slowly and let them catch and then the boat does the rest. I am a tab guy just because they save drives, not that the boat needs them. I run it to 2000 or 2500 with tabs. Not much difference but with tabs there is no vibration.

You won’t run a 4 blade again after the 5 blade max. It makes the boat run on rails in the rough.

Got a chance to run it hard today in the spring poker run an she ran great out front, had to hammer the props pretty hard to get them to bite out of the hole but once they bit the boat loved the rough.

Orderd up the new 5 blade Hydros, testing next week.

5 Blade Hydros
 

I was wondering how the test went with the five blade hydros and which 5 blade series and pitch that you are testing.

I'm curious about the Hydro's also :eureka:

Finally had some time to dial it in with the new bravo 4 32's and with the merc racing prop slip calc we are at 21% prop slip with full fuel and 4 people, we are running it friday with 1/2 fuel and 2 people to get the second set of numbers on the 4 blades, we are installing the 5 blade 28's next week in stock form to get the same two test numbers and then Lab from there. Just wish I had more time but moving along nicely, finally getting better on getting it on plane and the boat loves the rough stuff for sure. Will post numbers on the new 5 blades after testing, I am pretty sure they will be much better.

5 bladed Hydros or Maxxies?

We know what the Maxxies do :grinser010: I'm curious about the Hydros :confused:

I like my Hydros!

What size are you running ?

We ordered up a set of 5 blade hydros to start with, should have results this week. Testing was cut short friday when we hit something submerged and broke a prop shaft, so fixing that monday and going from there. But we had it running real strong with 2 and half fuel. Will post numbers as we get it dialed in.

Dude! Jeez! What props were you running? Any damage?

30" P5X's

Flenner what RPM's are you turning at what top speed? Also, what diameter are the props and what engines and HP are you running?

Sounds like parts in the one drive just behind the prop shaft, pulling apart today to repair the mess, some light damage on the skegs but not to bad, ran into a low patch of sea weed and some rocks in a place where we have run hundreds of times with no problems. will be running the hydro P5X 28's the end of the week, been trying some stock bravos and labbed bravos just getting around 22% prop slip with them, I think the Hydros should fix that though.

I have HP500's that have been worked. When James owned the boat, he recamed them with some other work. Horse power I don't know but it's around 570. I love the hydro props but I am going to have them reworked to about a 29 pitch. They are a 15 1/4 diameter. When it gets really hot, I am only able to spin them to about 5300RPM. The fallowing is what I have written down from a testing session last year.

3500-52
4000-62
5000-79
5500-84
top speed was 89mph

At the end of the day what are you looking for? Top end or cruise. You won't get both without two different sets of props so save your money.

The boat runs fastest with 32 Labs. 5250 at 87 and 18% slip. Now it kinda sucks coming out of the hole but it's a sacrifice. Midrange slip is higher but I'm thinking fuel cost CAN NOT BE on your mind.

5-blades will give you better mid-range but, then again, I've never won a race in the midrange....

Mark, could you post the numbers that you have on the Maxmus 5 blade props so that we could see comparisons to the Hydromotives. Does your boat have stock 525's as the boat with the Hydromotives had engine modifications.

Not the same power. Can’t compare.

Pat is right, 32 labs give you the best top. Mid range is only 1-3 mph less. You can’t expect to go from turning a 32 to a 28 and compete on top. The 5 blades are a good 84-85 mph wheel. My prop slip with 5's went down to 13-14% but I am turning 4 pitches less wheel. If you could turn a 30 lab max that would be the ticket but the boat won’t pull more than 5000 with that wheel.

The advantage of the fives is handling and getting on plane. Hands down better. Some will sacrifice 2mph for that.


These outputs are done with a stock 525 boat with ¾ fuel and one adult.

I agree with Pat and everybody else. I like the 5-blades for the midrange/handling and is the reason I went with them.

I wish I had your money. :evilb: You live in Mich ?:eek: WOW New boat, new props, broken drive.........I am glad someone in Michigan is doing well.:drink::drink:

I have really enjoyed the thread and am anxious to hear what speeds you get. :drink:

Pat you are correct, Fuel cost not so much on the mind for sure, the best combination I am attempting to get is a decent hole shot with the best top end for those runs when you need it, would like to see a mid teens prop slip with a 85ish top end with the 525's.

Might end up having a poker run set and a daily driver set if that is the way to go, we will be upping the motors over the winter to fresh 509's and whipple ready, so top end will be there for sure.

Just have to add that this is the most fun we have had and just love the looks and ride of the 37 AVH, we even had the coasties helo pace us this last weekend running on lake erie, was pretty cool.

Will post numbers as soon as the drive is back together. Going to run the Hydro P-5X 29's to start with.

New Hydros are in and ready to run.

I've been watching this thread closely as I'm in the same boat. I'm fairly sure I will need a new set of wheels after this little engine project we're wrapping up. I am very interested in the Hydros.

No, yours is teal and yellow. His is blue with lightning bolts....

We came into P-I-B friday walked over to say hi after dinner but you were gone did you boat back to Mi. First time I have seen the boat in person VERY NICE
Steve

Oh stop you're killing me. :lolhit:

Sorry we missed you, we ran over to get dinner and burn of some fuel so we could run it with light fuel on the way back but broke a drive on the return trip, thank you I love the looks on it as well.

Where you the Hustler right across from us ?

Skegs repaired today after strike.

Broke the lower shaft but good.

Yes we were staying with Jim at Fox's Dock. How far is it from PIB to your home port and how long does it take? Good luck on the repair. I'm happy to hear it was nothing more serious, but still puts a damper on the weekend.
Steve

We put in at Gibralter and we make it there in about 30 minutes, Parts going back togeher nicely and should be running again this week with the new props. That was a nice looking Hustler you where on.
