    New member! Swapping 2005 RXP to 2004 GTX SC

    Really wanting to know what I'm gonna need to complete this swap. Which drive shaft would I need to get? I can't get a clear answer for this one. What parts can I use off of the rxp? Ecu, gauges, prop? What do I need to do about the DTS? Any advice would be greatly appreciated!! Thanks!

    DTS? You will need to use all the electronics from the RXP, mpem, ecu, etc. Driveshaft from the GTX and prop from the RXP.

    I gathered some info about the drive shaft and I want to say the splines were different on the drive shaft from the 185 to the 215? Is this true? I meant VTS, the 04 GTX did not come with the trim system and I was curios to know how the ski would react electronically without it hooked up.

    You can have the trim disabled with a programmer or by the dealership. Otherwise, it will likely say "sensor" on your dash and you will get an error code for the VTS. It won't change how the engine runs though.
