I'd go one step further and suggest getting a true OMC Service manual as well as a parts manual. Mine set cost about $100 and it's been worth EVERY PENNY. I've read through the service and parts manuals several times and found them invaluable in defining areas that I have needed help with. If I'm unsure about something I'm reading, I usually post a question and see where it goes.
The guys on this email list are pretty laid back and very helpful. The guys on another major site are pretty knowledgeable and helpful too but they will lay into you if you don't have any manuals to research on your own.
It might seem like a lot of money but it sure has saved me from making several mistakes along the way.

Nexi,
If you have not opened that gear assembly up DON'T.... yet, you are going to want to get a seal kit with gaskets, o-rings and such to put it back together properly. That little saucer looking thing that the tilt gear is on is your tilt clutch/worm gear assembly, a cool little feature I'm glad OMC put in (more on that in another e-mail later)
You have an electrical problem you need to fix before you open that can of worms....get it? worm gear...:-) sorry bad pun.
Anyway, I'm gonna go out on a limb here and say you have a bad tilt motor...why? glad you asked.....you said that you get 12VDC at either solenoid when you flip the switch in either direction. The tilt motor is supposed to turn one direction for up and the other for down. So the electrical current when the switch is up flows through the windings of the motor in one direction and when the switch is in the down, the electrical current flows the opposite direction. In order to get 12DVC in both Solenoids in either up or down you must have a "dead short" between the blue and green wire. Most LIKELY that is the windings of the tilt motor itself. My suggestion would be to replace that before you open up anything else.....It's a little bit of a pain with the hammer gears and such but look like you will have the luxury of a little room to work so should't be that bad
I would highly suggest you invest in a solec manual for stringer outdrives or at least spend some time on Lee's site, you'll be amazed at the stuff you'll learn by reading through there even if it doesn't seem immedately relevant to your 120. he does a great job of telling the history and giving a good understanding of how these things actually work. When I first started messing with my sportsman Lee's site and ultimate.com/omc-boats (sorta the omc boats version of google)
Lee, do you have that troubleshooting guide posted somewhere Nexi could grab it? You did an awsome job explaining all of this tilt stuff.
Cheers,
B.C.

I tested the big bolts on the opposite side of each solenoid and those both have constant 12VDC.I did follow the 'soda can' and looked on the outside of the transom and see a piece with a gear that seems to do the tilting. I'm going to open that up tomorrow and see if perhaps it's gunked up. Will take a pic after I open it and post.

OK the pics help a ton!!! yep the previous owner spliced in some red wire to your tilt motor.....you can see the splice where it goes from blue with a stripe to red wire , the other is green with a yellow splice to red wire....the green should get 12 VDC when you press the tilt button down, the blue should get 12 VDC when you press the switch up...
The good news for you is that it all looks pretty easy to get to unlike those of us with the 155's. check those connections and voltage on the blue or green on the solenoids if that's all there.... you have a new battery, so I would suspect the tilt motor itself.
Good luck
B.C.

the big cylinder is the starter. One red is definitely power to the tilt motor (via the starter post) The other red wire is probably coming from the battery. On my '64 Buick 155, there's a blue and white for up and green and white for down. (confirm up vs down - i'm going from memory here). Not sure what the green and yellow wires are. Plain green sounds like one of the shift wires. Yellow doesn't sound familiar - maybe added later by someone...
Lee has some wiring diagrams posted - wiring diagrams look intimidating at first, but can become your friend after studying them for 2 weeks straight:

I'm thinking that I can check the motor itself by running power straight to it. Only problem is figuring out what wires are what. I see 2 red wires going to something cylinder in shape on the bottom of the engine compartment just next to the drive. Then I see a green and a yellow wire going out through the drive section and don't know where they end.

I can't remember if they mount to the stern drive housing or the engine block, but there's not a lot of real estate and they should be easy to find either way if they're in the same place. There are 2 solenoids, one to the left and one to the right, (up and down I think, but again can't remember for sure as that repair was a good 20 years ago).

> I went ahead and bought a battery, Marine - Starting, and started testing things out on the dash. Blower checks out ok but the tilt isn't working. I can hear a clicking in the rear when I flip the switch, but the engine isn't tilting. From researching a bit it seems the tilt is controlled by a solenoid. How do I track down the problem? Is it possible that the solenoid is bad even though it is clicking? Bad contacts perhaps?
