Are you talking about the Tilt and trim motor,that makes the motor tilt up and down?
What exactly wont your T&T motor not do,theres a few thing that can go wrong with it.could be electrical, you should check the fuses to start, then theres relays that stop working and more..
Are you sure the motor is full of ATF fluid,top it up,to be sure.
I dont know if theres a rebuild kit,
We have twin 2002 four stroke EFI, Question do you have to say four stroke if you say EFI ?
Anyway, we can get our T&T motor/pump for about $125.00, the point you need to expand your search, search harder.
