OK, well the drives are still on the boat so I'll assume that they are 1:36's like Philm says. That formula made no sense to me. I shoulda stayed in school like my dad said. I get the point about making too many changes at one time. I think I will send these 30's out and get them labbed and see if I have any improvements with these drives. I guess then the next thing is I will put on the Imco's and give them a try before the seasons end. 90's are OK for me I guess this year since I'm still getting used to this Cat hull. Hey Philm, I'll be heading down to the Goose for Aug 1st weekend. If your out there try and look us up. The details are on the Philadelphia thread, Thanks!

Scott, thank you too, always good advice! Bill
