and are there any modifications to make thanks for your help I have bought this lower unit and it appears that it will fit. I dont know much about these but i would assume i need to have th lower unit in the neutral position when i install it. But i have turn the spindle both ways as far as it goes and no matter where its at it seems to be staying in the same gear which i believe is forward. How do i get it in neutral? Also i changed the impeller as it has been sitting in a garage for 7 years. Is there anything else i should do before i put it on my motor?

OK Jeff, now you have this merc head scratchin. What part is not compatible? Oh I know, depends on if it is a v6 or an inline? The inlines bolt up....I think. All mine are the other way, never had an actual inline 150 original lower end. Lots of others.
