If the fast idle lever does nothing when lifted, most likely there is something wrong with the control box….Have an assistant lift the control warm up lever while you are watching the cable back at the engine to see if it is moving. Perhaps the sync/link/control cable adjustment at the engine is messed up causing this symptom…Perhaps the control cable is kinked, or too long with too many bends in it….
There is only one seal on this PTT unit, and it is where the tilt cylinder piston comes out of the cylinder…..I’m thinking you would be able to see any leakage in this area….Are they any other external leaks evident? The unit is filled when the engine is in the full tilt up position, be sure to support it somehow while you are working under there. Remove the large fill plug located near the top of the unit, then add GM dexron II transmission fluid (red), or the OMC power trim/tilt fluid (golden color) until it overflows out of the fill hole.

The fiill plug is #30 in the diagram, the manual release valve is #8.
Check the manual release valve it should be tight….Try backing it off a bit and retightening it….Please remember to support the engine in the full tilt up position while messing with the release valve so the engine doesn’t come down on your fingers….Once you have filled the unit and checked the manual release valve, run the unit up and down a few times, let it bottom on both ends of the range to get any air out of the system….I’m assuming this is a fresh water unit, trying to loosen release valve on a salt water unit could be futile…. If problems persist, I would order a new manual release valve….You must remove the snap ring in order to remove the release valve completely….Once it is out, check to see of the little rubber seal is still present on the inner end of the valve. Oil will probably leak out if you remove the release valve, so you will have to fill and bleed the system again….
And yes, the power trim unit is more than capable of holding the engine in any position, if the tilt pin can not be moved to the center hole…This engine does have a trim position sender mounted inside the port stern bracket, so you can easily add a trim gage on the dash to help position it correctly at slow speeds…
