Hello my name is ***** ***** am I speaking with?
Just to confirm. You removed both trim hoses from each cylinder, and you still were not able to compress either cylinder, is that correct?
Hi Tom. Are you boating in freshwater or saltwater?
I'm here. Give me a moment i'm looking for a picture.
Click this link to pull up a parts diagram. Let me know when you have it up and you can see it
You have 1 of 2 possible problems.
1. The trim ram is bent.
2. The end cap seals are corroded and pinching the ram. This is very common in saltwater used boats.
In that picture, #22 is the end cap, and #'s 17, 18 and 19 are a series of seals and scraper rings that are pressed into the end cap.
Over time, in saltwater, what happens is #17 18 and 19 corrode, and swell up, causing the trim ram to get pinched. If you are working on this yourself. What you would do is stick the trim cylinder in a vice. And then with a tool called a pin wrench unscrew the end cap. And pull the ram out. The first thing would be to inspect the ram and see if it is bent. If it is, replace it. If not, what you would do is replace the end cap itself. The end caps come loaded with new seals inside of them. So there is no need to try to pick and pull the seals out of the end cap, simply replace the cap which comes with new seals in it.
Does that all make sense to you?
I think that should do it. But I work for tips so I do want to make sure you are happy with my service before you go. If you had a further question on the issue by all means feel free to ask. If not, Just in case you do not understand the way the website works (and some folks do not). You do have to put forth a positive rating in order for it to credit me for helping you. When ratings are not done, the website simply keeps your deposit and they will not credit me. The ratings box is located at the top of the screen. To rate, you must select the star you wish and also confirm it. Please let me know if you run into any problems or errors when trying to do it. If you do have a problem, or if you can not see the ratings box which is at the top of the screen. Please reply back "I rate Jason's service _______" and fill in the blank.
Questions do not close out, so if you have to come back later on with follow up questions to the issue you still can even after doing a rating.
Thank you and happy holidays!Jason
Tom I do this for a living. I live in SW Florida on the gulf in the saltwater. I repair a few dozen sets of trim cylinders every year for this same problem. Bring the boat to a dealer, and then please come on back and let me know I was correct. If the cylinders will not push in with the hydraulic lines disconnected it can only be 2 things, bent cylinders or bad end cap seals. There is no 3rd or 4th or 5th possibility. There is nothing else it can be. This is not a new problem for me.
