I took a good look at the plastic reservoir on my trim-tilt unit, and saw several small cracks. Looks like this might have been completely failed this season, so I think I caught it in time. The trim-tilt works fine, just leaks oil into the bilge.

Has anyone replaced this type reservoir, and if so where can I buy one? There are no part numbers on the reservoir itself, but I believe it's a standard issue on older Sea Rays.

Also, are there any special techniques when reinstalling, as far as bleeding the system, or any special ways to re-pressurize?

Here is a photo of the unit in the boat:

And here is the part that needs replacing:

Thanks for any suggestions!

Update.... I just found what looks like the right part, and at a great price. Unless anyone knows different, I'm going to go ahead and order this part. Hopefully it won't hold up my launch date, which should be in about two weeks.

OK, the M525 was the right part and all is well. I'll have a much cleaner bilge this year. At $36.00 sure beats replacing the entire unit, or buying the adapter kit (200.00+) that changes it from a one bolt to four bolt model.
