Housing is exactly the same size on both.
Every part is identical except fuel out.
Had a small air leak in my original so I took the fuel out fitting and put it on the 50hp one.
Going to fire it up tomorrow
I have a VRO pump off a 2002 Johnson 90hp and one from a 2001 50hp.
Is the only difference, is that the fuel/oil mix outlet is smaller on the VRO from the 50hp?
Thanks
I found this on another forum.

Lower left i connected back and according to this reply the upper right Tee is venting into air silencer. Makes sense because i was careful when i removed. Thanks for the help i will update if i find anything else.
Just to update. Replaced drive shaft seals and good to go. Pressure tested and no leaks. Put LU back on and what a pain to get the shift rod back on the lever. I dropped the side pans and removed the air silencer. When reinstalling the air silencer there is T with small tubes i think for a vent...

So to clarify>>>
"The easiest way to tell if it is a 60° V-4 motor is the pan mounted trim switch is on the port side."
Also you're saying my outboard uses many years LU's
If/when i need to order maintenance parts what year do look up?
Thats where my confusion is
Yes that is the idea. I had a little water in the oil when I changed it for the winter. I have no idea what water pump or seals were put on so my plan is to change everything out. I just thought someone might be able to ID this lower unit. Once I get it pulled I will update this thread. Thank...
I'm not putting down an aftermarket LU. I've read both good and bad things about Stern Drive. I just want to get this over with and identify the lower unit that is on my engine. LOL in all honesty all this research has taught me a lot
I'm thinking this is an original gear case. UP is stamped on top. (Just like this OEM) attahed pic.... Obviously all this will be confirmed once I pull the lower unit. I'm just waiting for my son to visit so we can get it off.
