Currently have a 1997 272 Sailfish (euro transom design) with 1997 Yamaha 225 OX66's on the back. Both engines have been reliable with little problems throughout their years. I have an opportunity to get me hands on a clean pair of 2008 250 Mercury Verado's with approx 1000 hours on them. Does anyone have any experience with this setup? Would it be too heavy? Any performance/fuel numbers?
