I have a 2003 236 with the 200 HPDI. I was prepared to order the 250 but the dealer recommended the 200 as a better fit since we have so many manatee zones that top speed is of little importance. I'm pleased with the performance, she jumps on plane quickly and tops out at 40.1 on the gps with half fuel. The motor is very quiet and the fuel consumption is outstanding, averaging better than 3.1 mpg...granted I'm ususally running light with just two people on board.
I'm very pleased with the boat, lots of nice comments in the marina and no problems so far with hardware or fit and finish. I think they are a great buy and definitely one of the better handling 23's available. I suggest seatrialing one back to back with your other choices....you will go with the Sailfish.
