Nice to see some people were following along. So you have a 24 (26.5) pitch one now. Let us know who it runs for you....

Thanks to this thread I got the right size.
I've been collecting 26's for my 21' Checkmate open bow and your thread let me know the difference between listed and actual pitch.
Great thread.

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.

You're going good....but I know you can do better if you tweak it.

I hear ya but I'm not sure what I would tweak other than making it thinner... I also have a 26" and it gains 100 rpm but loses 2 mph with me alone and 1 mph with a load. I'm very curious to see your results!

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 !

'I want to try a t1 on my fatshaft sportmaster is that possible are they still making them?

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.

IM going to buy one after reading your post maybe i better go 1'LOWER , planning on a 24' do you think that huge cup is the reason for being so stiff? maybe get a 23 to be safe? i got mine bought the 24" glad i did rpm right were i wanted it and fast best prop ever on my set up;

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.

a scorpion owner told me pitch is acurate as marked with his info i did the math and and he is right on with his claims his slip# @ 10% running 58 mph 24 pitch 5400 rpm 1 87 lower ? sorry 55 mph.

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.
