Raw Water System
CAUTION
!
If a hose ruptures, turn the DC MDP
washdown breaker OFF immediately.
Close the thru-hull valve before per-
forming maintenance on the sea
water pump. Operating any pump
from a low-charged battery can lead
to a pump failure. Keep the batteries
properly charged. The raw water sys-
tem must be properly winterized prior
to winter lay-up. Refer to section 12,
Winterizing.
Perform these routine maintenance proce-
dures to maintain your raw water system:
• Check all hoses, and especially the sea
water hoses, for signs of deterioration.
• Remove and clean the livewell, air con-
ditioner and washdown pump sea water
strainers, as needed. Spray the pumps
and thru-hull valves with a metal protec-
tor periodically.
• Drain and clean the fishboxes and live -
wells after each use.
• Operate all thru-hull valves at least once
a month to keep them operating proper-
ly.
If a hose ruptures or leaks, turn off the wash-
down pump, using the WASHDOWN switch
at the helm or the WASHDOWN breaker on
the DC MDP, immediately. Keep the thru-hull
valve closed when performing service on a
sea water system.
CAUTION
!
Maintain a proper charge on the bat-
teries; operating the pressure pump
from a battery with a low charge could
lead to pump failure.
The raw water system must be winterized
before storage. For more information, refer
to section 12, Seasonal Maintenance.
Drainage Systems
Perform these routine maintenance proce-
dures to maintain your drainage system:
• Clean the cockpit drain rails with a hose
and water to remove all debris.
• Clean the hardtop leg drain holes, espe-
cially before winter storage.
• Clean the bilge pump and automatic
float switch strainers of any debris.
• Check the bilge for debris that can block
the function of the automatic switch.
• Test the rear automatic bilge pump
switch and the high water alarm float
switch each time the boat is used, for
proper operation. Operate the knob or
lever on the side of the switch until the
pump is activated, or add water to the
bilge until the water level is high enough
to activate the pump.
• Flush all gravity drains with fresh water
periodically, to keep them clean and free
flowing.
• Clean and inspect the shower and sink
drain sump system periodically. Remove
accumulated debris and flush with fresh
water. Test the automatic sump pump
switch for proper operation frequently.
• Clean and flush the fishbox and cooler/
storage boxes with a mild soap or a
bilge cleaner and fresh water after each
use to keep them clean and fresh.
• Operate the thru-hull valves once a
month and service as required.
• Check the drain system regularly to en-
sure it is free flowing and that the hoses
on the thru-hull fittings are secure and
not leaking.
