Lower unit with number 4

[stuw pidasso]

Hello All,

This is on a 1988 125 HP model 1251X8A Long Shaft. My Prop Shaft has a slight bend in it about 10 thousands of an inch.
Is this to much to run?. There's no vibration.

Can someone verify that the # 4 on the Lower unit by the fill screw means it's from a 125 HP motor, And a # 3 means it's from an 85 HP motor?. (I think it does but I can't remember )

Does anyone know the gear ratio for the two Lower Units?.

What other Year Lower Units can fit the 1988 125HP?.

Thanks In Advance

Sent U a pm with the parts cross over.
Just make sure the shaft is the same length.
