Can anyone tell me will a lower unit of a Mercruiser alpha1 outdrive from a 4 cylinder engine work on a Mercruiser alpha 1 (1986) outdrive with a 8 cylinder engine.

I broke the skeg completly of my lower unit at the bullet so I have to buy a skeg and weld it on. But my brother has a old alpha 1 lower unit from his boat which was a 4 cylinder engine. If his old lower unit will work on my boat powered by a 8 cylinder that would be the best way for me to go that is if it will work
