I second Mr. Sarna- Buy what your mechanic likes to work on and has the most experience with. All lines have had their issues- coils, knock sensors, fuel filters, etc. I have an 09 250HO on a puma ftd. I runs better than a boat should. Would a 250proxs run the same? Sure it would! Have a few folks around here had problems with their blue or black motors? Sure they have. You can go back and forth with this all day. It all comes down to your dealer/mechanic situation.Last edited by clownshoes on July 20th, 2009, 6:15 pm, edited 2 times in total.C.O.D. Jr. III
