Solas Scorpion prop test

[allstock]

[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]

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 use the stock small holes as my template and ran a 3/8 thru on my drill press. love it! my 24p turns same a 26 bbchopper top end same but better lift less torque smoother. my srx cant even come close.

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.

my nose searches , searches for more MPH! GOT MINEnew on savvyboaters.com sale$ 350.

Got a 27 Scorpion on its way from Bass Boat Central. Excited to try it

[bigboy]

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...

[vnemous]

Big Boy what motor you running. Im thinking of running a 3/8" bit before I even try it. I believe somewhere in here Doc said thats what he did.

[bigboy]

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

Yeah 1/4 is way too small. Im also considering drilling 3/8. But wont be easy with a hand drill.

[vnemous]

Yeah thank god Fullers Marine is also a machine shop

[whipper]

With these fit a TM small shaft gearcase? Will they take a merc flow torque hub?

[bigboy]

I have a fixed hub for small shaft. Newer ones have own removable solas hub but think only for fat shaft.
