Has anyone replaced the hydraulic arm on the trim tabs?

Yes. Was there more to this question or was it just a general wonderment?
Why do you need to replace it? You can change the o-rings without removing it from the transom.

The piston or ram separated from the cylinder. I'm thinking I need to replace the entire hydraulic arm (cylinder and piston). So I was wanting to see if anyone has replaced it, before I order the parts.
SeaRay has used some custom actuators in the past, do you have a photo of the other side with the Tab retracted? That way I can get you the correct part number.

They are pretty straight forward, other than accessibility, which is always a challenge in boats. The ram is held onto the boat via the screws you can see from the outside. But first, on the inside, you remove the nut/tubing and then unscrew the brass 90* adapter.
However, you've gotten the attention of our resident expert (although I know for a fact that he cheats on us and is other forums, as well! ). So I will defer to anything Tom wants to add.

Awesome! Thanks againCheck out the BoatLife products - they actually cure BETTER is the presence of moisture. Normal splashing that would happen around your dock will be totally fine. I just wouldn't use the boat till it's fully cured as you don't want to "force" the sealant out.

Your tab looks exactly like mine did until this AM! Your luck your mount is above water, mine wasn't so I had to do a short haul this AM.
Tom will need to see the good one retracted (up) all the way, and if possible clean it up a bit so he can see the rings going around the bottom of the upper cylinder.
Tom,Yes I need to see the other side fully retracted and know how many raised rings there are on the cylinder body. I suspect it is a standard A1101A actuator but want to be sure.
