I have a 89 390 with cat diesels for 4 years. my wife & I love the boat for its room, large frig., deck space & ride you get a lot of boat for the dollar. there was two things we where looking for when looking at the 390 express. one big one is we had to have diesels performance an economy. second late 1988's an later have the arctic white hulls. the only problem we had was the starboard cabin window leaked but was a fairly easy fix. good luck on your search an if you have any other questions we would like to hear from you.
