What happened to Grizzly and the Solas props?...offerings...

[Lenny]

I would love to get my hands on a Solas as in the style Grizz and a couple of others were trying. 24P LH or so.

Anyone got any news on the Solas product?

[Bad-Tat]

The Grizz has been busy getting his lake house finished. Will bug him for you when he gets back from Miami!!

Word is some props are now here in the states with pricing being ironed out right now. Don't quote me but it looks like they will be priced in the mid 300's.
Once all the selling details are worked out, we will be the first to know.

Everyone that is interested in these props that are designed for the older Volvo 17 spline drives PLEASE SPEAK UP.

Guys,
The props are here. We are working out prices etc. In a post last night I stated we are trying to get in the mid 300 ballpark. This is a test because I told them we could sell some because no one else will bother making props for the old drives. They flew over here and tested on my boat, I was impressed because it was better than anything I had used before including my Hill prop and an ultra I borrowed. The only draw back is you can not yse the big trim fin that is used for underwater exhaust. the little thin one must be used on the 250-270 drives abd the long hub cone. The 290 is not affected. This was a long up hill battle but the powers to be beleived in me. I will be bringing them to rallies also Their are left and right hand rotation. these are big props 15 1/2 diameter. It is a permanent fixture on my Corsican. Beleive it or not the 21 performes better than my 23 Hill.

I'm in :yes: LH please

In chatting with you Grizz, it would seem the 350 (mine) probably doesn't have the cajones to spin a 23... I can spin my 24" Ultra RH at about 5200 with a 1:61.

Does 21 sound right?

You other fellas that tried 'em, what do you think for pitch?

[David O]

Lenny,
Here's a copy of what I posted for numbers right after testing the props with Grizz.
I don't remember the numbers exactly but I do remember crusing at 50 mph gps @ 4600 rpm with a 1.89 ratio drive. I topped out at 54.4 @ 5000rpm using the 23 inch pitch prop.
Using the prop calculator that computes to a.056% slip for the prop.
If I can find a 1.61 ratio drive and increase my horse power to turn the 23 at 5000 I will have a top speed of 63.9 mph.
So, you are correct you probably wont be able to turn 5000 rpm with the 1.61 drive and a 23 inch prop unless you have the ponies.
You will be very pleased with the 21; if I remember correctly I topped out around 5300 with the 21 using the 1.89 drive so you still may not turn 5000 with the 1.61.
I have found a 1.61 drive and am going with the 23 inch and will add the ponies as needed to turn the prop at 5 or above.

David, when I did my slip calculations on my Ultra it came in at about 20% :eek: I couldn't believe it but have been told the Volvo is VERY hard to push around underwater. If you have slip numbers like that then obviously that prop and everything else involved is functioning flawlessly.

My 24" running at 5200 and a 1:61 should see about 73 mph in a perfect world.
I am seeing about 58-60. About 20% slip.

Also, your supplied numbers don't work in my "in my head" prop slip calculator. :D With 54.4 at 5000 and 23" P and a 1:89 I predict a perfect top speed for you boat of 57.61 MPH. So the 54.4 is actually 5.5 % slip is it not?

Yes
I used this calculator for my numbers and it shows slip as .0558 which is 5.6% slip .56 would be 56% slip. http://www.hillpropellers.com/propcalc.html

I also have trim and had Big Grizz coaching me on the use of it. May have had something to do with so little slip and may also say alot for the props.

[BigGrizzly]

Lenny, David is too kind. The fact is the prop being a modern design is more effient. On my boat the fastest top speed with the props was with the 21, the 1.61 and about 5500->5600(I was a little busy to get an accurete tpm reading but the top speed was 67. that time it had half a tank of fuel and I was by myself and the boat was just floating on a little 3 inch chop. The other runs were between 63 and 65 with no chop at all and I had another person with me - a Solas engineer. The RPms veried with the load from 5100 to 55 depending on load. As David can verify I always carry two gps with me and and verify my speeds.
I will admitt thad Davis was learning his boat all over again with the new props. They were more stable. Also he hadn't deiven his boat much due to prop and lower unit issues. The only problem he had was giving me the props back. at the end of that day I was his new best friend. His smile made me Know I was right to stick this thing out for so long and get them rolling on the project.
Just so everone KNOWS, this was made possible by rhe responces of the Donzi Net after my first post. Thank you Scott for making this possible.

[Dredgeking]

i'd like one for my 270 on my 16' donzi. i've been waiting for a while to see what happens. my only problem is i have no idea what prop is on my boat now. it's stainless, but has no numbers on it. frustrating. i don't know where i'd start for prop size. i don't even know what gear ratio my outdrive is.

i hate not knowing.

[Lenny]

Dredge, you will probably be running a 21 in these new props. As for ratio, it is one of three. Turn the motor over with the kill switch activated. Mark the prop TDC on one blade. Mark a pully on the crank.

Basically, you will have either 1:89 turns of the motor to ONE of the prop but MOST likely, you will have 1:61 turns of the motor to one of the prop.

What have you got for power? Grizz told me that with the 1:61 and under 350 REAL horse, the 21 is the ticket. Obviously these props bite hard and Davids' 5.5% slip factor is GREAT for these drives.

I have a SS Chad Hill with no markings either. ??? as to pitch but I was told 26. Interesting enough, I can turn the 24"P Ultra with no problem, and am seeing a heavy 5200+ rpm with me on board and FULL fuel. I also have about 20% slip. :eek: Apparently I will NOT be able to get these RPM numbers with the 21"P Solas. :eek:

I can't wait and the price offering is great if you ask me. :yes:

[BigGrizzly]

Dreg, What engine are you running and Hp it has.On our 16 witha 302 ford I can bearly turn a 21. However it turns a 22 Michican wheel prop fine to 4800 giv me more tio go on. Lenny Whith what you said I bet it is a 23 Thrasher this is what all the Hills from Ron down to Chad. I got the same results with a 24 ultra and my HILL.

[Dredgeking]

i have a zz4 350 with 335 to 345 hp. my carb needs to be replaced. i have a 750 holley on it and the secondaries don't open up. i never get over 5000 rpm right now.

[BigGrizzly]

Dreg that power puts ou on the same level as my Corsican. Remember the 21 acts like a 23/24 and the 23 acts like a 24/35 pitch. Normally one inch of pitch is 200 RPM with these props it is more like 300+ RPMS

[penbroke]

When (and where) will they be available?

Anybody have any photos?

[JimG]

I'd love to try one. My slip numbers are HIGH on my Ultra... :bawling:

[David O]

Jim
Are you turning left or right hand? I hope to have one each 21 & 23 LH in my hands very soon and soon there after one each of the right hand props also. Seems you will be making a trip to northwest Florida soon.

Right now the details are still being worked out on pricing, dealer networking, distribution, who is and who isn’t stocking them, etc.
I assure you we will know what's up ASAP.

David

[JimG]

David, I'm a lefty.

We are looking to come your way sometime this spring/summer. Maybe I'll drag my Donzi, and we'll hook up for a trial...

[BigGrizzly]

I'll be stocking them soon waiting for some paper work. Jim the 21 will have less slit than the 23 Ultra. In it day the Ultra was great back in the 70's. Now modern designs and blade progression are a sicence no longer black magic for the most part. This much I will tel you is- David is a believer as well as me. The thing is I would Like to know who would like to buy one. I do suspect there will several Ultras on E-bay soon. There will be left and right. I usually have one on hand with me for testing.

[Marlin275]

The thing is I would Like to know who would like to buy one..

I might be interested
I got a 26 Left Ultra
Stock crate 350/240? hp

What performance would I see?
6mph more?

[Lenny]

Grizz as stated earlier, in an email, I will take a 21LH and most probably a 23 LH. I don't want to try them, I want to bolt them on and use them. ;)
