The SaniPottie 974 MSD is a portable toilet with a 2.5 gal holding tank, built in ABS with a smooth finish. A push-button flush draws on a 2.3 gal supply tank, and the tank carries a prismatic level indicator and a pressure/vacuum relief valve. The MSD version has a 1-1/2" hose port, so the tank can be pumped out at the dock without moving the toilet. The body measures 12-1/2"H x 13-1/8"W x 15-1/4"Deep, and stainless steel mounting brackets come with it.

Our take

The 1-1/2" hose port is the feature to plan around: it lets the tank be pumped out at the dock while the toilet stays where it is. Check the 12-1/2"H x 13-1/8"W x 15-1/4"Deep body against your space.

From our buying guide

A vessel with installed toilet facilities must have an operable marine sanitation device that is labeled or certified. EPA says untreated sewage may not be discharged within three miles from shore, and in a No Discharge Zone treated sewage may not be either.

Check before you buy:

  • You have what it needs, since heads may call for 12-volt power, through-hulls and seacocks, or a separate vacuum source.
  • It fits the compartment, since Jabsco says an electric toilet needs more space at the rear than a manual one.
  • If it could sit below the waterline, you'll fit a vented loop as the maker specifies, since Jabsco warns the vent, not the loop, is what stops the siphon.
