[C38] replacement head

Fri Sep 6 14:05:39 EDT 2013

Just finished writing an article on the head, Chuck has it to submit for
a future article in main sheets.  But a couple tips form it, use muratic
acid or unchloric acid to clean the scale off the hoses and the head,
will go along way to eliminate smell and make head work better.   Flush
vinegar once a month down head to prevent scale build up.  Scale will
build up with any head flushed in salt water.

Ray:
 Jabsco 29090. Same as the old one that lasted for the 11 years of our
ownership. It was pretty new when we bought the boat.
You will have to replace the joker valve and the flapper valve every
year or so if you don't flush a slug of fresh water 
as you leave the boat each time. Uric acid malforms the rubber in the
the valves and crystalizes on them.
The main reason that I chose to replace the head was that the plastic
wore out that receives the screws holding 
the plates that contain these values. I had the choice of new head and
smiles from the ladies, or taking the old one
home to the shop, hope to be able to fix it, then spending another
potential sailing day screwing around with reinstalling
it. 
     I  have the old head on the work bench and see that I could have
drilled out the plastic and glued in drywall 
screw anchors to refurbish the failed screw-holding plastic.  $200 well
spent. We are ready to join the
chaos of the Americas cup spectator fleet this weekend.

Anyone want the old head? It has a new pumping unit.

	Don, 

	A new head is high on my wife's list, so I guess it should move
up on mine.  Which brand and model did you pick for the replacement and
why?

	Thanks much,

	"Its always something." The past week the head went from bad to
worse. I replaced the whole damn thing.
	These cheery looking Jabsco heads are really pretty flimsy when
you get them off for inspection.
	$200 bucks with tax. Money well spent for the odor suppression
and to please my wife and daughter.
	Gawd, what will break next?

		Hi Steve,

		I have a backstay tensioner, but it's only on when we're
sailing.  When the boat's at the dock, the backstay is left on just
enough to keep the headstay from flopping around.

		Latest theory is that when I replaced the two bolts that
anchor the stem fitting to the deck (a few weeks ago), there was enough
slop in the bolt holes that when the headstay was tensioned, the
fiberglass in the deck was loaded in compression until the stem fitting
moved back just a little to where the two bolts and the stainless stem
fitting picked up the load again. If that's what happened, the cracking
in the fiberglass shouldn't get any worse.  Does that sound believable?

		Thanks,

		Ray

		Esteemed C38 Gurus:

		Hoping you can help advise on my latest old boat issue. 

		I have some cracks showing up (and growing) on the
outside of the hull in the few inches between the ends of the toe rails
and the headstay stem fitting.  The cracks are horizontal and about 3
inches long. On one side the crack is about 1 inch below the deck.  On
the other it is right at the edge of the deck.  

		It appears that the headstay load is pulling the bow
upward, and the last few inches of the bow doesn't have the toe rail and
bolted hull-to-deck joint of the rest of the boat, so it's bending a bit
and the fiberglass is cracking. On the inside, the heavy stainless
backing plate for the strap running down the stem also stops several
inches short of the bow, and that may be a contributing factor.

		I'm wondering if this is a problem with the early boats
(mine is hull #37) that they fixed at some point. Any thoughts on known
or proposed fixes would be appreciated.

		Thanks much,

		Ray Torok
