Dave,

   Great writeup.  Any pictures of the new unit or any of the steps along
the way?

tankhoses

I have a '96 (?) 320, (#445) and put in a Raritan PH-II head.  Actually went
in fairly easily.  My biggest concern was removing the old head, without
dribbling bad stuff around. 
I left the old exhaust hose attached at the head, and removed the tank end.
Using a cutting wheel/Dremel tool got thru the wire reinforced hose fairly
easily, which then made it easy to remove from the tank fitting.  Stuffed
newspaper and plastic into the open hose end, and then covered the end with
plastic and some duct tape.  Also stuffed some plastic into the open tank
inlet..never smelled or saw any bad stuff. 
Unbolted the old head, carefully removed it and the attached hose, and
placed it into two, heavy duty garbage bags.  Dragged up, and heaved over
the side, for two points into the garbage pail.  I filled the old Jabsco
mounting holes with white Marine Tex.  First time I used the stuff, and I'm
not in the craftsman category, so there are two small, noticeable dimples
where the old holes are. More effort would make it look better...I'll need
to work on that. So much for the removal.

I spent a good bit of time placing the new head.  Required much test
sitting, measuring, and analysis.  Fortunately, it provided a good place to
sit and read the instructions.  Also note that the exhaust hose fitting
needed to be rotated 90 degrees....easily done on the Raritan. 
Then marked the six mounting hole locations and carefully drilled.

Put in place the new exhaust hose, Trident Super Premium (#102) white
sanitation hose, through the bulkhead hole, and then attached  the head end.
Moved the  head into place, lining up the holes.  The toughest holes were in
the back, with the one under the exhaust fitting the toughest.  Used 3M 4200
around the bolts/washers, and installed the head.

Note that I removed the hose that came on the head from the flush water pump
outlet to the bowl inlet, and used the vented loop hoses for that segment.
Also needed a new hose from the raw water strainer to the raw water inlet on
the head pump.  That's a bit different, as the water inlet for the Jabsco is
in the rear (as I remember) of the unit, and on the Raritan it's on the
front.

Finally cut the appropriate length on the tank end of the hose (used a
hacksaw), put a bit of Ivory soap on the fitting, and on to the tank it went
(remembering to remove the plastic stuffing first).  Still have to do the
hose support mounts on the two wooden cross pieces that sort of hold the
tank in position.  And of course, need to test it, end-to-end, once the boat
launches.

I don't want to start the job until I am certain I have the supplies
necessary for reassembly.  However considering the cost of the hose I don't
want to buy a lot more than I need.
