Can someone let me know if tach kit part #6YR-W0035-E1-00 is the correct replacement when repowering from 2 stroke 0x 66 250hp 2000 year model to
F250 four stroke 2006. If not what is the right part #

The 2006 motor would need 6YR-W0035-E2-00 Multifunction tach kit, the E1 kit is for 1994-2005 motors.
