Marine Sanitation System

Waste in the holding tank can form methane, an explosive gas. Keep

vent open and clear of obstructions. Keep fire and flame away when

maintaining the system.

It is illegal to dump plastic trash anywhere in the ocean or navigable

waters of the United States, including the Great Lakes. The dis-

charge of other types of garbage is permitted outside of specific dis-

tance offshore as determined by the nature of that garbage.

All recreational boats with installed toilet facilities must have an

operable Marine Sanitation Device (MSD) aboard. Vessels 65 feet

and under may use a Type I, II, or III MSD. All installed MSD's must

be Coast Guard certified. The Holding Tank installed in the Chris-

Craft is certified by definition under the regulations and is not spe-

cifically labeled. Do not flush foreign objects down the MSD. Dam-

age to the system may result.

The Marine Toilet Owner’s Manual that comes in your documentation package addresses the use, mainte-

nance, and troubleshooting of the system. It is your responsibility to become familiar with its contents as

only rudimentary information is presented here. Chris-Craft uses a porta potti for most standard installa-

tion, however on the Launch 28 and Corsair models a Tecma toilet is available as an option.

A portable toilet (MSD) is available as either standard or optional equipment, depending upon the boat

model. A self-contained toilet system is simple to use and maintain. Disposal of waste consists of remov-

ing the holding tank and transporting it off the boat. Dispose of the waste properly at a dump station or

other approved location. Do not dump the contents over the side.

The Tecma units utilizes a grinding system that grinds all waste before it enters the pump. This system vir-

tually eliminates clogging while consuming very little water. The cycle is completely automatic and works

on a 12/24 VDC electrical system.

The Tecma system can be configured with one of two types of control switches: a one switch unit, or a two

switch unit. With the one switch unit, a specific quantity of water remains in the water closet. Pressing the

button begins the automatic flushing cycle.

With the two switch system, the water closet remains completely dry. Press the “Before Use” button to

send a specific quantity of water into the bowl. Press the “After Use” button to begin the automatic flush-

ing cycle. This leaves the water closet clean and dry.
