10.1.5 Freshwater System
The freshwater pump is mounted to the hullside and can be reached through the access door in the
starboard gunwale. The pump is connected to the 20 gallon freshwater tank located in the hull forward of
the starboard fuel tank. The tank is filled through a fitting located on the starboard side of the deck. Similar
to residential well pumps, the freshwater pump pressurizes the system to 60 psi. then shuts down until the
pressure drops below that level. Most owners leave the pump “on” throughout the day, and use the system
when necessary. On the 2740, the freshwater pump feeds the pull out shower located on the aft transom
wall, freshwater wiper rinse and the marine head. To view the layout of the water systems see the diagram in
section 10.4.2.
10.1.6 Seacocks
Ball valves (seacocks) are installed on the water intake for
both the livewell and raw water system. The seacock must
be in the open position for these systems to work. When
open, the handle will be parallel to the valve. In the closed
position the handle is perpendicular to the valve (see picture
on right). World Cat recommends that the seacocks remain in
the closed position when not in use, or when the boat is left
unattended to prevent the vessel from taking on water due
to a plumbing failure.
10.1.7 Livewell System
Your 2740 has a 20 gallon livewell system which is supplied by a dual purpose livewell pump. The pump is
located in the port bilge compartment and can be reached through the inspection port in the motorwell. The
wiring is secured to the pump using a tie-strap, and must be disconnected prior to removing the pump.
The livewell pump draws water through the strainer mounted on the inboard side of the port sponson. A
seacock is installed between the pickup and the pump to allow you to seal the system between use, or in the
event of a plumbing failure.
To operate the livewell, first verify that the seacock is open, then check the y-valve located in the rigging
space beneath the livewell. To access this area, use the inspection hatch located on the starboard vertical
wall of the helm leaning post. The valve allows you to choose between the overflow drain for normal
operation, and the end of day drain for residue removal and final draining. When you have completed these
steps, engage the livewell pump using the switch at the dash. Water will fill the tank until it is level with
the overboard drain, which evacuates water through the hullside. To clear bait residue from the tank during
operation, temporarily change the orientation of the y-valve. When you have finished using the livewell,
remove the water by changing the y-valve to select the lower drain.
OPEN CLOSED
NOTICE
While underway, leaving your livewell seacock open could result in inadvertently filling your livewell.
To prevent this, close the seacock when the pump is not in operation.
NOTICE
Operating the engines in reverse can cause excessive ventilation near the livewell intake, causing the
pump to airlock. To prevent this, turn the pumps “OFF” prior to any continuous or high speed reverse
operation. If your pump does becomes air locked, turn the pump “OFF” for 15 to 30 seconds to
correct the problem.
