motor will not go down

[dad2rlkm]

Today my motor was tilted all the way in the up position and stuck there. It will not go down. I have read other posts where folks talked about relays etc.
In my case, the motor does run when pushing down or up. I honestly believe there is no fluid in it. I unscrewed the hex screw on the right (the reservoir?) and didn't see any.
When I buy hydraulic fluid, is there a specific marine grade hydraulic fluid or when any type work? If I fill it properly, should it start working?

I appreciate any help you can provide.

low fluid should not keep a motor from going down, but it will keep it from going up.
Have you checked to see it the tilt lock is engaged?

Thanks. The tilt lock is not engaged. Also, I found the info on the fluid to use from another string.

Still scratching my head on why the tilt will not go down.
