What the other outboards with similar hp and years use the same lower unit as the 1987 Mercury 90 hp (long shaft - 20")?

I have a 1987 Mercury 90 hp 2 cycles 3 cylinder outboard (Serial No: 0B194831 Model No: 1090727).

What the other outboards with similar hp and years use the same lower unit as the 1987 Mercury 90 hp (long shaft - 20")?

Any unit off a pre 1993 70/75/80/90 3 cylinder looper will work, if you go newer it will require shift shaft replacement...
