Yes it is, that's why you need to get some help.

Worst case, you could get an automotive eng. hoist and strap and raise it by yourself.

TBird here are some pictures of my old engine.There is a picture on the port side of the motor that illustrates that fluid is under pressure when Engine is trimmed down only fill when engine is trimmed up. Is this where I would add fluid to trim motor?

You`re right T Bird! I got back there and gave it the old "heave ho " and it moved (after I turned the manual release screw which I knew nothing about pre Youtube video) enough to give me hope.I`ll have to rent a Hoist . I don`t see any signs of leaking hydraulic fluid ,would`nt there be spots underneath it if it were?

You might not notice oil on the floor under the motor if it is on a transom saver because there wouldn't be any pressure on the unit. Chances are you lost fluid. If that is your issue, while on the lake using the T&T. the water would wash away evidence of a leak. Raise the motor and put on the locks. Check the fluid, if low, fill till it runs out. Lower the motor and try to pick up with the T&T motor. If it still does not move, repeat the process. If and when it starts to move you should hear a gurgling sound. This is the air if the system. Keep doing this until everything moves normally. If you have a leak you should see it around which ever cylinder is bad. If the leak is on one of the 2 title cylinders you can replace the seals without removing the unit, If it is on the main ram you will have to remove the unit and pull the cylinder apart. Not a hard job, but time consuming. Let us know your findings, it may help others.

On my engine the "fill screw" is just above the picture on it`s port side. Is there another fill screw hidden underneath somewhere?

Just putting fluid in doesn't always fix it. You have to get all the air out of the system when you let the fluid level get too low. Go on YouTube and there should be plenty of information on how to do it correctly.
