Creaking Trim Rams ???

[HiZ]

Ok, I have a 90 Nova with SBC and Gen 1 Alphas
When I trim up the drives, or down, they creak really bad
I have lubed and greased them w/o success
Any thoughts on this?
Boat sat for approx 2 years and I purchased it

Help!?!

First purge air from hydraulic system. Add correct amount of fluid with drive in down position. Run it up and down one time and check fluid level again. Run the drive up and down several more times; that should purge air. You should inspect the fluid itself to check for water in system. If so, then rams need attention. Good luck.

thank you very much: I work late tomorrow but will update this post when I get out there and give some attention
That's some direction!

Unhook them and then try it. So you can see if it is the rams or the pivots in the helmet, may even be the ram bushings.

It's not the hyd rams. It is the drive pivot points.

That's what I was thinking too - just groaning like some old birds
haven't been out to the shop yet, but tomorrow! I hope! Oh, I do

Water Boys, Water!
Good call on all the above~seems that water on the seals makes some awful
noise

So what did you have to do to eliminate it?

 

[HiZ]

Popped off the lines and drained the system: filled, purged and repeated for good measure, after the first session of the flush it almost eliminated all of the noise and issues.
Has been working great to this point, only 2 sessions of water time, but working well!

Good to know, thanks. I'll try to find room to file that away in a brain cell somewhere for the next time it comes up.......

Copy that, when you were in the file did you come across any information on exhaust for the same application
