28 scorpion..... What props?
 
I have been told that 25 mirage plus is the props to go with... And that's what I have. But I have also been told its a high 70's boat. I'm turning my 25's at 5100 rpm and running right around 73-74 GPS. On a prop slip calculator that's right at %9 slip , that's seems to good. But I'm lost as to how I can exspect to go any faster with these props? Oh and leading edges have some small nicks in them but I'm afraid to send them off mid summer unless I have to.

http://bblades.com/ Brett has given a ton for advice. When I get to replacing my props I will be using him.

I messages him... He offer to sell me his boat. He messages back once asking if I bought the boat I went to look at..... That's all I have heard from him. I'm sure he is busy getting his boat ready for summer/sale.

Are you spinning your props in or out?

what props are you using? yes Mirage Plus is the only way to go.

I can put mine at 80... gps.

A friend of mine has the same boat and power, and also looking for props. Are most people running the 3 blade mirages. Has anyone had anyone had any improvement with 4 blade bravos, if so what size?what did the cruise speed do ?

[ATTACH=CONFIG]504363[/ATTACH]I'm spinning out...and it looks like they are going out to get trued up....... The bad part is ... I had a talk with the crew about putting the ladder up 5 min before it happened

Well beleave it or not Air marine called today and told me the the props were fine. I had them sharpen them up. I got my dash out for new gauges so I think I'm going to flip my cables on my shifters now and turn them in. I was told docking would be a bit harder and I might get some chine walk... But should gain a few MPH.

why did you take them their?? i had a viberation in my boat and had them look at the prop and they said their was nothing wrong with it...i reinstalled it and their was still a viberation..so thats when i founf dah propeller out of wis and sent it to john,,air marine did not measure all the blades i guess because dah found that one of my blades were bent and charged me 175.00 to lab and blueprint the prop..i got it back and it was smooth as sild and my boat went 6mph faster..

I was told they were a good place. Local shop uses them alm the time. I was gonna go to DAH.. I was worried about the turn around time. Ill prob by a set and send them to DAH or B blades .... I tried calling those places... AIR Marine was the only place to call back.... So they got my $$
