You don't have to spend that much
And it'll cost you more than that...'cuz it either has to be installed by an "authorized" V/F dealer (average cost $1000+) or inspected by one (at your expense for their time) or your warranty is void. It's a fine toilet, but there are other toilets now that offer everything it does and more for as little as 1/4 the price. For less than $400, you can buy the pressurized flush water version of the Raritan SeaEra, which doesn't use any more flush water than the V/F REALLY needs (it CAN use as little as a pint, but it's rare that it doesn't need a couple of quarts), is VERY quiet, macerates--which the V/F doesn't do, doesn't have large separate components that eat up a major portion of the storage space on your boat--and you can install it yourself without voiding the warranty. It's available as either a complete toilet or a conversion kit that'll save you even more by allowing you to re-use your existing bowl. Everyone who has one loves it. All the specs including the owner's manual are on the Raritan website at http://www.raritaneng.com and the chandlery here sells it.
