The head macerator pump and a “Y” valve are installed in the forward bilge. You can access the pump
and valve by lifting the floor hatch that is installed in the deck just forward of the seat on the front of the
console. The head macerator pump is used in the overboard discharge operation. The “Y” valve must be
in the correct position to direct the waste either overboard or to your marina’s dockside discharge
facilities. Before utilizing the dockside or overboard discharge functions, make certain that the “Y” valve
is in the correct position.
The “Y” valve is installed on the port side of the pump. It allows you to switch back and forth between
dockside and overboard discharge. The photos below show the 2 positions for the “Y” valve (i.e.,
dockside discharge vs. overboard discharge).
Dockside discharge - When at a marina that offers dockside
discharge, the marina will provide the external facilities needed to
perform the dockside discharge operation. To operate the dockside
discharge, turn the “Y” valve to the dockside discharge position as
shown at the right.
The “Y” valve for the Electric Head as shown here is set to use
dockside discharge. Follow the arrows. Waste is going from the
holding tank, to the “Y” valve and then upward to the waste outlet.
The waste outlet is a stainless steel fitting, labeled waste. It is located amidships on the port gunwale.
Twist the waste outlet cap to open the fitting and insert the hose provided by the marina into the waste
outlet to connect to your marina’s dockside service facilities. Follow the instructions provided by the
marina to operate their equipment.
Warning: Waste in the holding tank can form methane, an explosive gas. Use suitable
precautions when any maintenance is done to the sanitary system.
Overboard Discharge - To operate the overboard discharge, turn the
“Y” valve to the overboard discharge position. The “Y” valve for the
Electric Head as shown here is set to use overboard discharge.
Follow the arrows. Waste is going from the holding tank, to the “Y”
valve and then to the electric head pump.
Then, go into the head area and flip the macerator switch to the on
position.
Before using the overboard discharge system, be sure to check with your local authorities, U.S. Coast
Guard, local marina or your dealer for the rules and/or laws that may apply specifically in your area.
Before operating the electric head system, refer to the manual in your owner's packet supplied by the
electric head manufacturer for specific operating instructions.
