SAILFISH 312 CC | TYPE III MSD WASTE MANAGEMENT SYSTEM
Installation:
The holding tank should be located close to the
toilet.
A proper seacock is required if the discharge
thru-hull is positioned below the waterline.
Both the discharge thru-hull and the holding tank
are installed to prevent a potential siphon. Contact
a marine plumber or Jabsco technical support
specialist for installation assistance.
Mount on a strong flat surface. Note: the area of
installation needs to support the weight of the unit
and its contents.
Four mounting feet (included) need to be attached
to the platform with four machine or lag screws
and four flat washers.

• 1 x 1 ½” deck pump out – evacuation pickup
tube (Install to dockside pump-out deck plate)

up of sludge or debris. It is recommended that this
process be completed at least once a year. Please
