[C320-list] New Head Replacment

[Scott Thompson]

I put that exact same head in my last boat and was very pleased with it. 
   It's a much better unit than the stock Jabsco, and reasonably priced. 
How well does it fit in your 320 and what were the difficulties with 
installation?  It would also help to know how old your boat is, because 
the head compartment design was changed at some point.  I forget which 
year that happened, but I know it was before 1999.  Everything I've read 
about heads suggests that replacing the hoses with high quality 
materials is as important as anything else you might do to keep 
performance high and odors low.

Not sure I want too detailed a "usage" report, but a report on the 
installation would be great.
