I recently purchased a 75 23' cc that has a stainless marine bracket and twin 1999 200 Mercury EFI's. I have only run the boat 3 times since I bought her and amd in the middle of putting in a new deck, painting everything and replacing all of the hardware. The boat is scary fast. I did not have my handheld gps when I got both motors up to 5000 RPMs but I know it was over 50 mph. Even with the floatation bracket the boat is a little heavy in the stern. I have put a little weight in the forward locker and this has gotten rid of this problem. I wish I could give you some numbers but I won't be able to for a while. I currently have a 120 gallon tank I am going to add another tank in the space right in front of the console. I think I will be able to add another 50 gallons or so up there. That will put more weight forward as well. I do have a 50-60 mile run each way to the gulfstream from where I put in though. I do think some 150hp engines wiegh identical to 200hp engines so you might want to see if you are really adding any weight or just more power.

Good luck with everything!
