I have pulled my hx, had it boiled at the local radiator shop and ordered the new Semdure gaskets and rubber washers that I found through searching old posts on this site. The new gaskets are a solid tan color and aren't in the four sections with the clear inserts of the old ones. I assume this is what I am supposed to have. Seems to me that a gasket is a gasket is a gasket, right? Also, does the washer go on the bolt (against the inside of the end cap) or after the gasket. Seems like the washer should go on the bolt first after the end cap. My old ones came off in pieces so I don't know for sure how they are supposed to go back on. If you have never done this, I recommend it. I am sure that mine has not been apart in the 22 years of the boat. Found a broken zinc and two impeller blades in the hx. There was so much calcium and lime build up that the new zinc would not go in until I had it boiled.

Mark,
Yes, as far as I know the rubber o-ring type washer goes on after the end cap and the Hx gasket goes on after that.
From the owners manual found on the wiki. a picture is worth a thousand words.
Here are all the manuals: http://www.c34.org/wiki/index.php?title=Manuals (http://www.c34.org/wiki/index.php?title=Manuals)
Go to C34 Tech wiki link at the top of this page. Easy.
Now, all we gotta do is get us guys to start reading the directions! :rolling
And while we're at it, PLEASE keep reviewing the CRITICAL UPGRADES. It's a sticky on the Main Message Board, ya can't miss it!
Thanks for the help. I have the actual parts manual and engine manual for the 25xp that I got from Westerbeke. I need to check again, but I did not find this drawing in there when I looked. I also have the Catalina manual that came with the boat, but did not think to look there.

Here's a pic of a Westebeke HX, same manufacturer as the Universal HX's..

If you don't want these to leak you really need to clean up the ends. Nearly every one I have seen tends to be pitted and very un-smooth from the factory. I use a piece of glass and some 400 wet paper then move up to 600 until it is very smooth. As for all the pin holes in the ends I fill those with epoxy mixed with cabosil and then fair it smooth.
Once cleaned up I treat both the HX and the end cap mating surfaces with TefGel and put it back together. ZERO leaks...
This is early in the process and you can still see how bad the surface irregularities are from the factory.

Hi,
I did a search on the web site and found these links on where to purchase the HX gaskets. The first link discusses how to make your own from a sheet of rubber too!
