Offshoreonly.com - ??? on Imco shorties & toe-out

I have a 97 35' Fountain w/565 hp @ 5800 rpm. I am currently running 89.6 on the gps at 5600 rpms. I am installing -2" imco's. My question is what have other people found as far as performance gains? Will I have to re-prop or will I pick up the extra 200 rpm's that I am looking for? As well as what speed increases should I except to see. I was told 5 mph. I question that number though.

Also, I have read some interesting threads on drive toe out. I am assuming that would make the props closer together? I have heard any wear from 1/8"-1/2" out. I have no clue wear mine are at now. Does anyone have any opinions on this or should I just check them and make sure they are at 0?

Any input would be greatly appreacated. Thanks in advance.
