RAW WATER SYSTEM
The raw water pump is located in the aft rigging compartment on the port side, and can be
accessed through the inspection port located on the vertical wall beneath the livewell. The pump
and wiring are mounted on the rigging wall at the back of the compartment. The raw water
pump is connected to the dual purpose livewell pump which brings in water through a strainer
located on the inboard side of the port sponson. The livewell/raw water seacock must be open
for the system to work, however, the livewell pump does not have to be “ON”. Similar to the
freshwater pump, the raw water system in controlled by a pressure switch set at 50 psi. The
pump will cycle on and off as needed to maintain this pressure. Most owners leave the pump
“on” throughout the day, and use the system when necessary. On the 270, the raw water pump
feeds the Hosecoil™ located on the port side of the leanbar. To view the layout of the raw water
system see the drawing on page 15.
HOSECOIL™
The freshwater and raw water systems can both be operated using the Hosecoil™ wash-
down hoses located on the leanbar. To operate, remove the cover plate and extend the hose
as far as necessary. Open the nozzle by twisting it, adjust to the desired spray pattern and
use similar to any residential water hose. When you are finished, close the nozzle and
return the hose to the cylinder.
MACERATOR PUMPS
Your 270 TE comes equipped with two macerator pumps which are mounted in the forward
rigging compartment. The pumps evacuate water and residue from the in-floor fishboxes and
the fishbox forward of the console (known as the “coffin box”). The coffin box and starboard fish-
box are tied together using a tee, which is located in the forward rigging compartment and can
be reached through the access hatches on either side of the console. The port fishbox is drained
using the macerator pump on its respective side.
To access the pumps, remove the access hatch using the fasteners along its perimeter. The
circuit breaker and wiring for each pump is integrated into the control unit on the console rig-
ging wall. To operate, use the switches located at the helm. The pump(s) will draw water from
the boxes, macerate any solid waste, and evacuate the remains through the hullside.
Macerator pumps are self priming, but are susceptible to damage during extended dry runs.
For this reason, the pumps are equipped with a thermal switch. The switch will cycle the pump
“OFF” to prevent damage from excessive heat caused by dry operation. If you have a pump cut
“OFF” during operation, allow the unit at least 15 minutes to cool before attempting to use it
again. While you wait, verify the contents of the affected box or boxes to be certain you have not
emptied them. Pay particular attention to the starboard fish box and coffin box. If one is empty
you may be drawing air into the system which could lead to overheating at the pump. To combat
this, plug the empty box and continue pumping.
! CAUTION
Foreign objects such as wood or metal should be cleared from the fishboxes prior to
macerating the waste. Failure to do so could result in damage to the plumbing or pump.
