im converting my 97 150 mariner mag 3 to efi bought an efi system complete bolt on and plan on putting it on this week but i was told that the stator or flywheel on a carb motor is different from one on an efi motor is this true because i dont want to get all the efi stuff put on and the motor not run hahaha

Nothin' ta do with either carb or efi. It don't mater..............
Ign don't care how tha fuel gets there..........Tha only thing I can think of that THEY might be thinkin' of is tha efi motor harness is a little different that tha carb harness.

No to hard if ya just pay close attention ta tha ones that come off and tha ones that go on (tha colors mostly). Tha efi will have a replacement of 1,3,5 coil and switch box wires. Don't have a scanner but a dia. would really help ya. Might do search and find one on here.........................
