My question is, my lower unit is good, my upper is toast. I talked to a guy that sells used parts, he sold me a 1966 mercruiser/120 sterndrive, he said i should be able to swap out the upper unit and put it on my 165, so i am thinking after reading a bit about this that it might work, the engine that the sterndrive came off of is a 160, so am i out a bunch of money or can this work?? somebody please help a guy out before the wife beats him to death with said sterndrive, joking or mabey not, thanks

Ayuh,... I Think,...

You might be able to swap the Whole Drive in 1 shot,...
Rather than using your lower....

Whether they'll Mix,+ Match, I'm not sure.....
Either way,...
Using the 120hp upper is a lower, 1.98:1 gear set,+ the160 is Probably a 1.84:1....
You'll need a Pretty Tall Prop to make it work....
