C. Water Heating Systems
The water heater used on 248/268 Vista model has a 6
gallon capacity. The water heater is installed on the port
side of the engine compartment on the 248 and on the
starboard side for the 268. Refer to Figure J1, J2, and
to the drawings at the end of this section.
NOTICE
Water heater location may vary due to the in-
stallation of optional equipment.
The water heater utilizes 120 volt (220 volt on 50 Hertz
models) power. The water heater breaker switch is lo-
cated on the cabin 120 Volt AC panel.
NOTICE
DO NOT supply 120 volt power to an empty wa-
ter heater. Damage to the heater will result im-
mediately. The water system must be filled and
primed before attempting to use the water
heater.
A water heater that incorporates a heat exchanger is
standard on the 248 and 268. The heat exchanger
allows the engine coolant to heat a portion of the fresh
water supply while the engines are operating. This option
will provide hot water at times when 120 volt power is
not available. Additional information on heat exchangers
is covered in the engine and hot water heater
manufacturers' manuals. Please refer to Section H on
Electrical Systems for additional information.
Exhaust Fumes!
Provide adequate ventilation at all times when
running the engine to warm the water. Hull
exhaust from your boat can cause excessive
accumulation of poisonous carbon monoxide
gas within cockpit/cabin areas (while underway
or while stationary). Engine must be off to avoid
potential carbon monoxide buildup.
D. Using The Shower
Turn on the faucets to desired temperature, move the
lever (diverter) on the shower head, and the shower be-
comes operational. The shower hose is connected to
the shower spout and connects to the faucet recep-
tacle, underneath the sink.

When using the shower, draw the shower curtain before
using the shower. Damage to the finish can result if
surrounding walls and flooring are allowed to become
excessively wet. Thoroughly dry these areas after show-
ering.
The water temperature can vary during shower
use as the pressure pump cycles on and off.
For greatest consistency, turn the cold water on
full, then mix in hot water until the desired tem-
perature is obtained.
A shower sump pump is incorporated into the drain sys-
tem of the shower. The shower drains into the sump
pump located forward of the aft cabin. The water will
then be pumped into a black/gray water holding tank.
The capacity of the black/gray water holding tank for
the 248 is 16 gallons (60 liters). The 268 has a 21
gallon (79 liter) capacity. If a gray water system is in-
stalled, the water will be pumped into the gray water
holding tank. See Section J-3 below.
The sump pump includes an automatic bilge switch and
is protected by a circuit breaker at the cabin panel. The
sump pump will automatically start as soon as the water
in the sump reaches a level that will cause the float on
the switch to rise.
After showering, let the water flow for a period of time to
flush the pump of soap residue. Check the sump for
excess residue. When rinsed out, the pump will auto-
matically shut off.
If water flow from the shower head appears to be restrict-
ed, it may be due to sediment accumulating at the shower
head. If necessary, remove the head and clean the dis-
charge holes with a fine wire.
Periodically check the sump pump screen for clogs to
prevent drainage problems from occurring in the show-
er drain. Refer to the manufacturer's literature included
in the owner's packet.

GRAY WATER SYSTEM - OPTIONAL
The gray water system is optional on 248/268 Vista mod-
els. The water from the galley sink, head sink and shower
will drain into a sump and is pumped into a 16 gallon (60
liters) holding tank. The waste level indicator is located
in the head compartment. A pumpout fitting labeled
