Anyone have experience with different years (newer) ECU used in older skis/boats?

Am interested in FX140 used in skis and boats
I know the first 3 years they had coils on side and no air pump in throttle body.

I am looking to replace a 2005 ar230 ecu - used ones I can find now are newer boat models, and some skis
Someone had posted on using a 2008 fx140 ski ecu in his ar230 2005 boat and having success...

A knowledge base on the ecu differences over the years would be beneficial to all.

anyone with any info please chime in!
