Raw Water System
Raw Water Supply
The 189FS and 203FS feature a single thru hull scoop pickup on the transom for raw water intake.
Livewell System (189FS and 203FS)
There is one 800GPH livewell pump. It is mounted directly to the thru hull pickup. The pump provides raw water to the transom livewell. The pump has
an independent switch and fuse(See Electrical Schematics). 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 with a corrosion inhibitor.
Standard Raw Water Wash System (189FS and 203FS)
The 189FS and 203FS are equipped with a raw water wash system. The system uses the livewell pump to provide raw water to the provided washdown
hose. Please note though that using the system does not allow use of the livewell. To use the system, unscrew the livewell fill valve on the livewell and
thread the hose onto the inlet. The livewell pump is not pressure regulated. Therefore, only engage the livewell pump when you are going to use the
washdown. Do not leave the pump on when not using the washdown.
Optional High Pressure Washdown system (189FS and 203FS)
The 203FS can be equipped with an optional high pressure, raw water washdown system. The system is fed by a pump that is located in the aft end of
the port transom dry storage compartment. The pump is controlled by a switch and fuse (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. The raw water pump features an in-line strainer for collecting any debris that could damage the pump. The strainer should be checked
before using the pump. 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, under the gunwale cap and adjacent to the port jump 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 Maintenance
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 pumps in
shallow/muddy water or water with high amounts of floating debris such as grass or trash may result in ingestion and damage the pumps. Loss of
pressure in pumps may be the result of contaminants blocking the thru hulls, binding of the pumps 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 livewell and/or washdown frequently. Any loss of
pressure or flow should be addressed immediately to prevent damage.
