I have an old 27'Omega I am going to re-power. It used to have a pair of 4 cyl I/O's and I'm thinking of hanging a bracket and a 250 on it. I've talked to one marina and they said it would probably perform better than it did originally because of the reduction in weight, but a friend of mine says I won't have enough power. Can anyone out there shed some light on this situation? Thanks in advance. <br /><br />Pat
