I purchased one of these for my boat
(exact same model actually). The MSD fittings are pretty useless. There is no pump
or even valve on the holding tank
, so the only place the MSD fittings can connect to is a deck
fitting for pump out. It can't really be rigged to dump overboard
without some other accessories. So I'm not using the MSD fittings at all.... much simpler to just drag it out and dump or pump the toilet itself.
