Update 2: got my boat back today! Had the o-rings replaced and impellers replaced in both engines. Little more than I thought about $409 but seems like it was a great job. Said both engines and boat have great bones for being 2001.
As I put boat back in garage I noticed one of the old impellers (not changed in my two year ownership) but glad it was replaced!!
Double checking to make sure won’t creep down but won’t know till tomorrow

So update 2: motor going down much faster. Mechanic before recommended me to get a rebuilt power and trim unit. He said that the O-ring kit doesn’t include one of the needed O rings do you have any suggestions on what to look at? As a rebuilt cost over $1500

Sorry you are still having issues. I just looked at Five Star Marines web site, looks like prices have gone up since they rebuilt mine.. Its possible there could still be a leaky seal/O-ring? Five Star did charge me more than their advertised price since they added some new parts. So far no problems with the rebuild.
Lund thanked you for this post
I would be upset that the mechanic attempted to rebuild yours without All the necessary parts. At this point, you have choices....
1. Take the unit back to the mechanic and get the correct o-rings installed like you paid for. (O-ring kits with them all are available through 5 star for $90)
2. Order a correct kit with all the o-rings and replace them yourself.
3. Send your unit to 5 star or other reputable rebuilder for a full rebuild. (5 star is $670 for yours I believe)
4. Buy a used (but good) P/T unit. (Ebay has several currently $500-1000)
5. Buy a new P/T unit (boats.net $3000) Holy cow!
Before I'd do any of that, I'd evaluate what the harm in leaking down overnight is vs. the expense. If you raise the outboard up and engage the tilt lock lever, it should rest there once leaked down and be of no consequence. Does it leak down while on the water and underway? If so it must be repaired.
Good luck!

I'm not a TnT or hydrolic guy.. looking at the first post I see that before the new O-rings were installed the unit was leaking down in 1 hour. Then looking at the parts diagram there are lots of parts in the unit. If the mechanic simply replaced the O-Rings.. he may not have cleaned up the rest of the unit. Some trash may be inside and may be causing the bleed down issue. I like to work on my own stuff but there are some things I just don't know how to do or have the correct tools. I don't have a hot tank or ultra sound cleaner. My TnT unit was leaking from the ram cap seals. Since it was over 20 years old and had never worked on a TnT unit..I sent it to a company that rebuilds them 5 days a week, Tears were shed over the price but I only cried once.

So it's "leaking" down faster? Or when you trim it goes down faster? If leaking then the "mechanic" didn't do his job. I've NEVER heard of any kind of rebuild kit that includes all but one part. Wouldn't that be silly? Especially if that happens to be the one that leaks the most times?
Agree with NCK, have him repair it correctly and then find a new mechanic.
So for clarification when the mechanic and a mechanic from another shop said "O-ring kit doesn’t include one of the needed O rings" it includes them all but doesn't include something to do with the valve. Sorry still learning about this stuff. Both mechanics from two different shops recommended to get a rebuilt or new TnT as apparently it is hard to work on the valve (not 100% why but okay). Hopefully this makes more sense to someone here than it does to me lol!
So it initially was leaking down slowly but now is still slow but fast enough to visibly watch it creep/leak down. It seems like it is getting worse. It does leak down on the water but slow enough with 1-2 second (maybe) up button press every 90 seconds (guessing). I can still get it to raise up to the lock lever. So I guess that means I will be getting in contact with Five Star and see if they can rebuild mine ($670) or buy a new one. Lucky 5 star has a remanufactured for $1,400
I like to tinker but I am missing some tools as well. But I am thinking the same as you, "Since it was over 20 years old and had never worked on a TnT unit..I sent it to a company that rebuilds them 5 days a week, Tears were shed over the price but I only cried once."
It is creeping/leaking down without doing anything. The power trim/tilt still works up and down the same speed but will not hold in position.
Also thank you all for helping me out!!!
