Motor identification?

[TrashPanda]

Does anybody know of motor identification numbers or exactly how to tell what size my “blown up” motor is. I am gonna get a rebuilt motor for my boat 2002 sportster le single motor. But while looking for motors I see different sizes. I believe that my motor is a 951 regular not di. Any help in identifying would be appreciated

Think there is only one . 951cc (called 947 sometimes)

There are only two, the 951 carbed and the 951 DI, you can also call them 947 but it is the exact same thing.
