I have a brand new 2003 21'boat, 350 MAG MPI, 300HP Alpha 1 drive. Shifting is very primitive, not like the omc I wish I had back. When you come out of gear to neutral the engine stumbles for 1-2 seconds and sometimes dies. This boat has the new smartcraft ECM 555 computer on it. It has been to the dealer now 9 times and they have changed 3 computers, 2 control box's, 2 remote shift cables, 3 shift interrupt springs and all adjustments.It is still the same!!!! The only thing left is pulling the drive and looking at the intermediate cable or drive unit itself. Anyone heard of this??????
