Livewell - Raw Water; Washdown Operation - Grady-White 330 Express Owner's Manual

Livewell - Raw Water

To operate the livewell, open the seacock with the livewell I.D. tag located beneath the center
lid in the aft berth. The livewell pump is screwed directly into this seacock. The livewell
switch at the helm should be in the "on" position. Place the livewell standpipe in the drain
located at the bottom of the livewell. Screw it down until the black flange makes contact with
the flange on the drain fitting. Water will enter through a plenum along the side of the livewell
and be distributed through a series of holes arranged vertically along the plenum. The water
will rise to a depth even with the strainer on the standpipe and drain overboard. To evacuate
debris and bait waste from the bottom of the box while the livewell is in operation, unscrew
the standpipe approximately three turns to expose two 3/8" holes located in the threads of the
standpipe base. This will allow a small amount of water to escape through these holes and
remove any waste that has settled in the bottom of the livewell. See "Livewell/Washdown
System" on page 29 for a layout diagram.
If the livewell seacock is left open and the pump is not on, the boats forward motion through the
water will gradually fill the box. To prevent this inadvertent filling, close the seacock when the
livewell is not in use.
Under certain conditions, placing the outboard engine(s) in reverse will ventilate the water under
the boat and create an air lock in the livewell pump. To prevent this situation from occurring, it is
recommended the livewell be turned off prior to any high RPM or continuous reverse operation.
If the livewell pump becomes air-locked, correct this situation by turning the pump off for 20
seconds.

Washdown Operation

To operate the washdown, open the seacock with the washdown I.D. tag located beneath the
center lid in the aft berth. Depress the washdown switch on the accessory switch panel. This
system will now be pressurized at the washdown faucet outlet. This faucet may be used alone
or with a hose. A hose with a spray nozzle attached may be used intermittently without turning
the switch off in the same fashion as a home yard hose with a nozzle. The washdown pump
has an internal pressurization switch that will maintain water pressure as needed until the
switch is turned off at the switch panel. The pump is mounted to the transom in the aft port
storage compartment. See "Livewell/Washdown System" on page 8–29 for a system diagram.
