Ran a Solas Scorpion 28 with interesting results.

I heard this prop has been a favorite for ski racers but have had to date no experience with it. Some have said it is very similar to a Yamaha T1 which has been a good overall runner when tweaked on my set-up.

Prop has 15-1/8" dia. blades, straight large barrel, a lot of rake with extra tip cupping for hard bite and high engine height running out of the box. It was stamped a 28 pitch and I did not have the time yet to get it checked for the exact pitch but its safe to say it ran more like a strong 30.

I had to drill in three 5/8" PVS holes as the pilot holes stock was not enough for acceptable hole shot.

Prop had excellent weight carry lift, bit hard and never let loose. I could raise motor until water pressure was too low using a coned lower and it still was biting hard. (long ears and deep tip cup working good here.)

Weather was hot, 88 degrees, light wind and approx. 1' chop. (not the calmest to test in and keep the pedal down, but I'm running a 21' w/21 degree deep vee original Challenger and it handles it well enough.)

1. Full load, 3 adults (520+lbs., anchor, fire extinguisher, bag of extra everything, extra prop, back seat (90-100lbs), stereo, 28 gal. of gas, full oil tank (2+ galleons). 5500 rpm @ 80-80.5 mph gps.

2. 1 person aboard, same load less 10 gal gas, 5600 @ 83.4 gps.

Slip # was a crazy low 1.71% for a 28 ! runs more like a 30.6 pitch if I do some math corrections.

My motor makes best power in the 6200 rpm range so it looks like I need to go down to like a 26 in this heat.

Note: It seems a good 2-3 pitch lower then normal might be a good place to start to try this prop.

Anyone else have any experience with one of there props ?

15 1/8" diameter? Wow, that thing must really lift. That slip number is mind boggling.

The diameter and cup no doubt added to lower slip numbers, maybe more then I figured on and made it harder to turn up top for sure.

The Rev4 is exactly what I thought as well when I read the description but the Rev4 does not like to be truly surfaced.

I have not Mike. I guess they run stiff also ?

I also tested it against a Turbo TXP 27 but that had less success in the handling and lift department so I didn't even try to run it out.

There was a thread over on the Checkmate-boat form on the Scorpion prop. Someone had tried one on a 21' Pulsare and said it was amazing. I tried one and was not that impressed. As mentioned it needs much larger vent holes to spin up for hole shot and they are very stiff in pitch. Maybe if I had tried 1-2" pitch smaller prop and had 6 PVS holes drilled my results would have been better.

Vnemous mentioned the Rev4. I use one and it is one of my best props. Unfortunately I think the max pitch made is a 25". I run a Croxton B&B 23" Rev4 with 8 PVS holes. My slip is about 5% and I surface it all the time. It runs similar RPMs to a 24-25" Bravo. I tried a stock Rev 4 and it would not spin up for hole shot with only 4 PVS holes.

vnemous
07-13-2015, 02:50 PM
Yes I tried a 21p rev4 on my 20 key largo with my 285hp 250 efi. Very hard to get out of the hole with four plugs out but once on plane it accelerated like no tomorrow and ran the boat to 70 very quickly. Would love to try one on my superboat but obviously need more pitch. Like said they only go to 25 pitch but I bet a competent shop could pitch it to 27

I have tried a lot of different props and varied set-up back and forth with changing results trying to find the best "overall" for most waters. My fastest speeds have always been with a props that has been 'worked' from stock.... oh, except for one or 2 that were custom to start.

I now have a few 'go to' props but like testing still because you never know.

You do look similar from here. :cool:





Update....... I am going to pick up the cut down Solas Scorpion today. I was told it measured to 30.5" on the tip and it now has lost 1/2" of pitch on the bottom-middle of the blades. It expect it measures 14.75" dia. now and I'm interested to see how it will perform comparatively to a couple yamaha T1's I have run that have proven to be excellent on my boat.

So if anyone is looking to buy a new Scorpion rule of thumb is expect they run a 'stiff' 2.5" pitch more out of the box !

Does the Solas run it's own proprietary hub kit or can you use Flo Torque kits?

It takes a 'Flo torque hub'. I Need that also to run my Fat shaft and yami T1's are only pressed in hubs for standard shafts hence my desire to check into them.

Here is my now custom cut, 14.75" 28. If you look at the trailing edge cup you can see how steep it is and that is stock ! The area just below the cupping measures 28 pitch and that's how they sell the pitch size. Pitch starts low down on blade as a 26 or less and has alot of rake. Also had 1/8" trimmed off leading edge which also depitched about .5" the low to middle area. Soon see what changes this makes.

update...New Cut W/Added 3- 5/8" PVS holes so I can adjust hole shot (take cheap hardware store plastic snap in plugs in 1/2" size to close or drill now for adjustment)

2 aboard, 3/4 tank fuel.....

80-82 degrees, 5-10 mph winds,too choppy to run full out however short burst ran 84.5@5600. Bites still very hard still, lift is great, holds nose high with good feel of stern control. (calc. slip around 8.5% for a 30.5 pitch makes most sense). Should be a good top end prop now also just have to do that some other time.

PVS holes were all open but now too much ventilation, hole shot spun motor spun over to 5500 before bite and grip. I think 3-1/4" holes might be enough now after trimming blades.

Can't test now for awhile but the cut worked out well. Went 1.6 mph faster@5600 with more weight aboard.

Yes lots of experience with them and on my rig they run 2-2.5" stiff. Slip runs 3% so clearly they are under rated on the pitch scale. I stopped blowing my horn on these a few years ago because all I ever heard was "oh they are cheap offshore prop gotta run a merc prop BLa Bla Bla....." I've run them hard for three years never cracked never thrown a blade and fastest numbers on my rig by far. I had my local prop guy drill them for PVS plugs which work great.

Run what 'your' boat likes as it's sweet spot.

If you run a coned lower w/ low water pick-ups I would guess 3/4"-1.25" tops. If its a torque master then lower of course.

I run a coned lower and W/Hydraulic Jackplate so dial it in as I run. Changes for each prop and water condition usually.

Great thread.

And nice snag on the prop price. Let us know how it runs please.

And if you want to play with it you have an idea how to give it a little trimming if you think the full 15 1/8" dia. is more then you need.

Another option after running it, if you want more rpm, might be to just try reducing the amount of cupping first and see how that works. I don't think I am done playing with mine yet and that's something I was thinking about.

Following for sure! I'm glad to see others giving them a try, you can buy two for the price of a Merc prop... None of which have worked as well as the Scorpion on my rig. Very interested to see how the mods pan out. For your reference I have the same motor as yours, a 2003 OX66 250 with a HPDI lower unit that I did a "lower" water P/U mod to. Checkmate Pulsare2100br. Currently running 85 mph at 6000 rpm with just me in it. Stock 27" Scorpion with pvs holes in it. Funny thing the boat runs 83.5 mph full of fuel and four people at 5900rpm. I have not had much time to really string it out with just me in it so there may be more there. Running 16" of setback 1.75" over the pad, runs out of psi long before bite.

Having a few T1's 29's that are faster then my Scorpion, hold bow as well and are 14.75" dia., I had the confidence that by simply reducing the dia. a touch would give me more RPM, easier to turn up to add speed hence my first tweak. Just food for thought.

This scorpion is not my fastest prop by any means yet but I love its lift and weight carry as noted. I would Like to see how fast it can be made to run and still hold the weight carry for a good all around prop.

Now....If I can next spin this 28 'mod' Scorpion of mine up to @ 6100rpm it should pass my best top speed of my T-1's and that will be awesome !

NO.....and they were only avalialble in 1" standard shaft w/pressed in hub that's why I am testing a Solas Scorpion because it is the closest replacement and available as a flo torq hub.

Due to the extra large cupping and long dia. (15 1/8") the prop runs 2 1/2 pitches higher then marked as a rule.

I have never seen the prop you speak of. Old or new? I don't know if a 24 pitch has same heavy cupping added as a new 28 pitch. If you read from the beginning you will see why I came to say add 2.5 " to pitch. It's from my actually experience and the prop being scanned. There may well be some exceptions.

Today was the big day!!! the prop is incredible. More than I ever expected. The pitch was correct, not too stiff as I had thought it would be. Ran about 6 mph faster than my DENNIS and less RPM about 5400 RPM. Right for a 2.0 150 hp. unbelievable lift all around. See boat on my profile as pictures as I can't figure out how to upload them on here. check out the red cat. 3 stills. but I have to say that it runs on my cat . I heard they ran great on vees but they sure work on my cat. mercury prop guys better get on the ball to beat this knock off prop. almost ran 70 MPH today, faster than any mercury prop that i had tried.

each blade carves a new path if you spin it and look at it from the side this is done as im told by their design rep so the following blade enters non aerated water behind the blade in front of it so if you spin them they look off ballance with relation to the blade tips

i sell probably 10 or more Scorpions a year and countless Lexor models and each one will semi surface and fully surface from the box... only in extreme bow heavy fishing boats does the tip cup need to be added to and thats only in none or very short setback lengths

Hunt around online you can find them new for below 400.00 and many new ones have flo torque hub set up which is more adaptable.

They are also listed as Solas S3 propeller.

They also must be run above the pad and the higher the better for best performance. If you find you have too much bow lift ( feels like the nose is searching ) then means you should reduce motor setback. Only prop I have found that could give you too much bow lift.

[QUOTE=allstock;2779594]Following for sure! I'm glad to see others giving them a try, you can buy two for the price of a Merc prop... None of which have worked as well as the Scorpion on my rig. Very interested to see how the mods pan out. For your reference I have the same motor as yours, a 2003 OX66 250 with a HPDI lower unit that I did a "lower" water P/U mod to. Checkmate Pulsare2100br. Currently running 85 mph at 6000 rpm with just me in it. Stock 27" Scorpion with pvs holes in it. Funny thing the boat runs 83.5 mph full of fuel and four people at 5900rpm. I have not had much time to really string it out with just me in it so there may be more there. Running 16" of setback 1.75" over the pad, runs out of psi long before bite.[/QUOTE

I was right, more there, light on fuel nice cool day 87.1 mph at 6100. I am going to try a 28" and see if there is more again! Even with the 27" the boat will plane with seven people aboard full of fuel!

Hi,

I bought on of these but the vent holes are realy small. Now I should be able to drill them out but I have the idea that the standard vent holes are positioned very close to the prop blade. Did you just drill them out or drilled offset? Any pictures of the PVS plugs and is it possible to do it yourself? I dont have a mill...

Thanks!

JPEROG
05-10-2017, 02:24 PM
Take it to someone with a mill. There is no "standard", you want them as small as possible but big enough to let your motor get into the powerband. I have several with 1/2 holes that do the trick.

I tried mine.... With the stock vent holes of 1/4" it was a pita to get it on plane. At first I thought I had to put the boat back on the trailer. Ran great otherwise. Good bow lift. Lots of bite. Ran 89mph at 6800rpm on my hst. Propshaft even with pad. Should have some more in it but did not stretch it out too hard.

I def have to enlarge the vent holes or get PVS holes machined but dont know where I can have this done. Not too much prop shops over here.

Wish I bought a 28 instead the 27...

Running a 2.5 200 merc! Offshore can but closed snout with block off plate. Open exhaust would prob make It worse.

Do you mean 2x vent holes on each blade so total of 6?

Gotta drill mine. Going out next weekend and don't want to risk to not getting it on plane. It was hard to get it on plane and just me in the boat with the pilot holes.
Thanks.

So I thru the boat in the water an hour ago just to see if she would get on plane. She did but it was tough, gonna need much bigger vent holes. For those that dont know my x has just a tuner and no exhaust can down to the prop so I dont get much ventilation. Once on plane it ran very well. 87 mph at 5800 rpms works out to 4-6% slip figuring the 27p is reallly a 29-29.5p. I had plenty of pedal as my redline is 7000 but I didnt have my vest on and this was just kinda a shake down to see if it would get out of the hole. More to follow.

whipper
06-09-2017, 11:57 PM
So when you say trouble getting on plane you mean spins up higher rpm but doesn't bite? Also wondering if maybe I should try a 25 instead of the 26 if they run that tall? I can spin well over 7000 but like to prop to 7200max. Want hole shot and mid range more than top end. I have a drill press and access to a Machinist at work for the 3/8 holes maybe 1/2 inch buy the sounds of it?

No the prop does not vent so it does not spin up. My trophy has stock vent holes with no plugs plus an additional 1/2 in holes and vents fine. Of course the pro et does not have this problem since its not a thru hub.

Just drilled them with a hand drill. Was a piece of cake.

I gotta say I LOVE this prop!!!! I had huge mph gains and it bow lifts like crazy. I tested pretty much everything under the sun last fall looking for the best lift and bite, did the merc favs, the evinrude standards, all versions of the raker, if it had rake and a good cup I tested it. I spun a 24p and managed to hit 72 in a sketchy furry. before that I was topped at 68. the 24 had me pulled down to far runnin 5100rpm. dealer didn't have a 23 in last fall so I just gave up. just added 4 more inches of setback and got me a 23 this weekend. water conditons were rough as **** but noticeable difference runnin at 45-50mph. I recommend this prop to everyone and anyone. its deff in a class of it own.

I have a Falcon F205 with 250 SHO came factory with a 24p Scorpion. I am running about 74 fully loaded at 5600 RPM. As I come up on the plate I start to get slip and cant get anymore out of the prop running higher than 2.5 PTP. Another guy with the same setup is turning a 27 pitch T1 6000 rpm ad 79 MPH. Is the T1 a better prop or do I just need to get the Scorpion worked. Right now it just has pilot holes. Should I get the pilots drilled out and try venting even with a SHO?

Thanks
