Raw Water System
The 239DFS features a raw water system for the transom livewell and raw water washdown system.
Raw
Water
Supply
The 239DFS features a single high speed venturi pickup for raw water intake. The pickup incorporates a seacock. Before using the boat, it is important
to note the location of the seacocks and the means to achieve access to them. In the event of a rupture in a raw water line or pump that allows
unrestricted flow of water into the bilge, shutting the seacock will be critical. Seacocks should be checked periodically and the valves moved to verify
operation and unrestricted movement. If problems are found, they should be addressed immediately by your dealer.
Livewell System
There is one 800GPH livewell pump. It is mounted directly to the seacock. The pump provides raw water to the transom livewell. The pump has an
independent switch and circuit breaker (See Electrical Schematics). To use the livewell, it is important to check and verify that the seacock is open.
Failure to open the seacock may result in pump failure if the pump is run dry for an extended period of time. The livewell pump is a centrifugal pump
that is not pressure regulated. Therefore, it is recommended that the pump only be used when using the livewell. The pump is self‐priming. Before
activating the pump, make sure the livewell fill valve is open and than switch on the pump. It is important to check the livewell pump annually and
periodically spray it/them with a corrosion inhibitor.

Washdown System
The 239DFS features a standard raw water washdown system. The system is fed by a pump that is located under the convenience center sink. The
pump is controlled by a switch and circuit breaker (See Electrical Schematics). Water is supplied to the pump off of the accessory port on the livewell
pump(lower hose connection on the livewell pump). Using the raw water washdown does not require the livewell pump to be on, however the seacock
must be open. Failure to open the seacock may result in pump failure/damage if the pump is run dry for an extended period of time. The raw water
pump features an in‐line strainer for collecting any debris that could damage the pump. The strainer should be checked periodically. If you are using
the boat in “dirty” water on a regular basis, it is recommended the strainer be checked routinely. The strainer features a clear cap for easy inspection. If
any debris is found, remove the strainer screen by untwisting the clear cap and clean the screen. The pump features a built in pressure regulator that
will shut the pump off when pressure is achieved in the system. The raw water washdown faucet is located on the port side, adjacent to the transom
bench seat. If trailering the boat or using the boat after an extended period of downtime, it will be necessary to prime the washdown pump. Before
activating the pump, open the washdown faucet and than switch on the pump. When the system is free of air, you can either close the faucet or shut off
the pump. It is important to check the washdown pump annually and periodically spray it with a corrosion inhibitor.
System
Operation
and
Maintainence
When using any of the two raw water pumps, it is important to pay attention to the water you are operating the boat in. Operating the pump in
shallow/muddy water or water with high amounts of floating debris such as grass or trash may result in ingestion and damage the pump. Loss of
pressure in pump may be the result of contaminants blocking the thru hulls, binding of the pump impellor, clogged strainer basket and/or blockage in
lines. When operating in the contaminated water, check the supply of and quality of water to the livewells and/or washdown frequently. Any loss of
pressure or flow should be addressed immediately to prevent damage.
