Hello!

I have a 1970 Mercury 1150 outboard and I'm having a problem with the
power tilt and trim.

Need more info ...

I put the motor in the full-up position and filled
the reservoir.

Why did you do this? Did it empty on its own?

After I did this the motor stopped going down.

Was it working before you did this ? If so (See above)
why did do have to put fluid in it? (missing details here)

Could be a bad seal in a cylinder. Are you doing this
with the cylinders dusconnected from the motor ?
