I have a 2000 mercury 90 H.P.4 stroke engin and it is the worst engine I ever owned.I have broken down 12 times,have been towed in from The Gulf of Mexico 6 times etc.3 days after th warranty was over I had to spend $1100.for repairs(rebuild 4 carbs plus.)I sent 4 certified letters to the president of Mercury and never received a reply.I had the motor in and out of the shop while it was under warranty also.I am a loyal American but will never buy another Mercury or other American motor again.The Japanese make quality motors and that is what I will buy in the future.Has anyone out there had similar problems?Andy
