moving to a -2 lower you have lost some leverage to carry the bow, I went through this with my boat, this can be corrected with prop tweaking

Default so what was the conclusion on set up??

what are the thoughts of -2 x with ITS system set back 7 inches? What props would you guys all suggest and why?

I have had 5 3100's ranging in power btwn them all. Most all of the boats porpoise between 75 and 90mph then work through it to a smooth run. I have not tried merc ITS and -2 all in one package so don't know what to expect? I am also going to move the motors 12 inches forward (or is at least the plan) with only about 600hp to 650hp a piece.

Thoughts or experiences on this?

Thanks in advance!

If you have not purchased your Merc ITS transoms yet, look on the OSO classified. Bob Leach is selling some for a smoking deal. I was thinking of going that route, and the best price BAM quoted me was 9995.00 Add to that the 5" Ziegler extension box (pricey piece) and you have a small investment in your outdrives. I am already committed to go with the IMCO boxes and use my existing Bravo transoms and IMCO steering system-----------but, if I wasn't, I would jump on the ITS system and sell my bravo transoms and IMCO steering system.

Thanks for the input ROTAX.......... appreciate the help, but I had already found my xr's with ITS drives. Turns out I am not going to move the motors forward, but am looking at -1 or -2 shorty lowers and am hoping to hear more thoughts from people on my scenario!

I also don't know which prop setup to go with. I have always had success with the bravo props and never tried the 5 blade. Thought on this?
Thanks a ton....

The only thing I can add to your great set-up is:
1) Add the 5" spacer
http://www.cpperformance.com/p-12356...pacer-kit.aspx
2) Add the -2" IMCO lowers

After that, suggest you call Brett at BBLADES and enlist his expertise in which prop to use and how it should be "tuned".

Randy, chime-in and help this ladd out. You have more on the water experience in this area.
