I am doing some research to see what issues I may run into swapping a blown CM2350 from a 21' pete 389 with a CM2450 from a totalled 23' pete 389. I would be swapping complete engines with ecms.

What challenges will I face?

Will the after treatment be compatible?

What wiring changes will I have to make?

Any help or insight would be greatly appreciated
