I have a 2004 model 203 and I can't say enough good things about it. See if you can have the motor checked out at a local dealer. They should be able to hook it up to a computer and tell you its history.

Sinc e there sem to be so many people on this board with 203's now , what kind of top speeds are you getting and with what prop? I run a 225 EFI with a 25 tempest. I run around 70 - 70.3 GPS with a tourny load, full live well and half tank of fuel.
