8. Drain the vinegar solution by opening all
faucets (hot & cold), setting single faucets
to the warm position, and empty the water
tank. When the water tank is empty turn
the pump breaker OFF.
9. Close all faucets.
10. Fill the fresh water tank with clean, fresh
water. The fill fitting for the water tank is

12. Open each faucet. When a smooth flow
of water is observed from the hot and
cold tap, close the faucet. When all fau-
cets are closed, the pump will shut off as

5.2 Raw Water Washdown
The raw water wahshdown system pump is
supplied by hoses connected to a ball valve
and thru hull fitting located in the midship
machinery space. The supply hose is labeled
WASHDOWN PICKUP at the ball valve.
There are three speed tap outlets on the boat
for raw water. One is in the anchor locker and
can be used to rinse the bow area, anchor
and anchor rode. (The second outlet in the
anchor locker is a pressurized fresh water
outlet.) Two speed taps are located in the aft
port and starboard corners and can be used
for rinsing the cockpit. (A second fresh water
outlet is located adjacent to the raw water
outlet on the starboard side.) Pursuit pro-
vides a supercoil hose and sprayer that can
be used with these speed taps in the boat
owner’s shipping kit.
Operation
Make sure the ball valve is open before
attempting to operate the raw water wash-
down system. Activate the pump by turning
ON the washdown switch on the aft starboard
cockpit switch panel. When activated, the
pressure switch will automatically control the
pump. As pressure builds in the washdown
hose, the pump will shut off. When the wash -
down hose is in use and the pressure drops,
the pump will turn on. Turn the switch off when
the washdown is not in use. The raw water
washdown is equipped with a sea strainer on
the intake side of the pump, located in the
midship machinery space; check it frequently
and clean as necessary.
Priming the System
Open the ball valve and hose connector,
and switch ON the WASHDOWN switch at
the helm. Run the pump until all air is purged
from the system. Close the thru-hull ball valve
before the boat is hauled from the water to
eliminate an air lock in the system. It may be
necessary to re-prime the raw water system
if the system is not used for an extended
period.
CAUTION
!
DO NOT operate the high-pressure
pump when dry, or damage to the
pump will result. Turn the raw water
pump switch OFF when leaving the
boat unattended.
