We changed out the aft head Jabsco for a Raritan. The Raritan was a little more expensive, but after nearly 5 years, I can tell you that when the boat is underway with a crew, the Raritan gets used and everyone ignores the Jabsco.
As for the physical change, I had to drill two new mounting holes because the base pattern is a little different, and I had to buy a straight output fitting to replace the angled one that came with the new head. Took me about two hours, start to finish.
As for the Jabsco, it's on my list of things to replace as soon as the boss cuts the money loose. They squeak, squawk, leak, stink, and backfill with water.
The Raritan has worked flawlessly except for an operator problem once. The boss's cheri' du jour put a 'little bit' of toilet paper in the bowl and managed to jam the joker valve completely. (The little bit was a column of soggy toilet paper 1 1/2 inches in diameter and 9 inches long!)
Anyway, ain't no big deal to change it out. Four base bolts, two hose clamps, and that's it.
Do yourself a favor, though. Before you disconnect the 1 1/2 inch output hose, buy a gallon of white vinegar at the grocery store and pump it into the head, let it sit a couple of hours, then flush it through using fresh water. The vinegar will deal with the 'biological' waste and break any salt in the hoses loose, to boot. For what it's worth, I do that to both heads once a month. The vinegar will also do a job on the barnacles on the through hulls if you're pumping directly overboard--off shore, of course.
