In the market to repower my 2002 Viper Coral. I'm on the fence between a Mercury 250 Pro XS or the new Mercury 225hp V6 fourstroke. I'm not that concerned about the top end performance. I really just want reliability and good gas millage. I'm nervous about being an earlier adopter of the new Merc. Price is almost the same. Not much info out yet. What do you guys think?
