My Center Console had a permanently installed Port a potty, it had a pump
out fitting and you could pump it out just like any other boat. Without that pump out fitting I wouldn’t be interested, but with it for a boat that isn’t full time they are great, they don’t have all the issues ones with tanks
and thru hulls and long hoses do.
It also never had a smell, the formaldehyde I guess took care of that.
However it could not direct discharge, nor could it pump itself out, you could install a macerator and a thru hull
, but for a boat that was only used occasionally, why bother?
For a boat that we only really used for diving
occasionally and didn’t overnight on, it was perfect, but then the little boat wasn’t really big enough for a waste tank.
There are two types of chemicals, one is a type of enzyme or similar and deals with it biologically, and one is basically embalming fluid, Formaldehyde, it works by killing any kind of life of course, the thing is you have to really, really clean it out well if you use the enzyme one if there was ever the embalming fluid in it, as it will kill the enzyme or whatever it is, and People therefore think the enzyme doesn’t work
, it does just you can’t mix it with the chemical that kills everything.
