•
Bilge Pumps
are both electrical and manual. Two pump intakes are located in the keel stub
under the main cabin floor, with a third intake attached to a coiled hose in the aft head. This is
long enough to reach the bilge and qualifies under ORC cat 2.
• The
Manual
pumps are operated from the cockpit and from the aft head.
•
Electrical Bilge Pump
is wired to an independent switch on a recessed panel adjacent to the
nav station.
Head System
The J/46 is equipped with two certified marine heads which are capable of discharging effluents into a
holding tank or overboard. Both systems are easy to operate and with correct usage and proper
maintenance, will provide many years of use.
Before operating the
HEAD
, ensure you have read its manual thoroughly and understand the proper
procedures. Silly mistakes can cause severe “head” aches at the worst possible time! And a word to the
wise
PLEASE TRAIN YOUR GUESTS ON HEAD OPERATION. NEVER, NEVER ASSUME THEY KNOW
HOW TO USE IT!!
The head is a large pump which takes in seawater and flushes waste into the holding tank or overboard.
The salt-water intake thru-hull is underneath the head sink and the discharge is in the port aft locker.
Remember open/closed positions on these thru-hulls. It is good seamanship to close the intake and
discharge seacock for the head when not in use.
When seawater and effluent are pumped through the head, they’re pumped into the holding tank by the
action of pumping the toilet handle. The waste discharge fitting on deck is provided so a shoreside pump-
out station (i.e. vacuum cleaner) can empty the tank. Care should be taken not to overfill the holding tank
as effluent can block the vent hose and may damage the tank... or worse, burst the hose. If the toilet is
difficult to pump, check to see if the holding tank is overfilled. “When in doubt, pump it out!”
The holding tank must be pumped out before winter storage. Dumping a quart of anti-freeze through the
heads will prevent the seals and equipment from cracking. For your information, the following hoses are
connected to the tank.
• Waste Discharge Hose from the head
• Pump-out Hose leading to the deck fitting
• Vent Hose to vent the tank overboard.
Electrical System
The following section describes the electrical systems aboard the boat, how they operate, where they lead,
and how to avoid trouble. Please read this section over more than once. For wiring code information
please refer to the color code diagram.
DC Electrical System
A 12 Volt DC electrical system is used throughout the J/46 for lighting and operation of pumps and various
accessories. The J/46 is standard with one 210 Amp battery, two 105 Amp batteries, and one 56 Amp
1,100 CCA engine battery. An optional 210 amp AGM is available and replaces the lower nav station
drawer.
