Raw Water System
High Pressure Washdown system (186BR)
The 186BR is equipped with a 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, however the seacock must be open. 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, make sure the seacock is open. 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.
Aft Livewell Recirculating Pump (Option 186BR)
The 210BR can be equipped with a recirculating pump for the aft livewell. A recirculating pump is a pump that pulls water from the bottom
of the livewell, aerates it and than returns it to the top of the livewell. The normal livewell system does this, however it is continuously
replacing water by drawing it from the raw water intake. In deeper water, this is the best way to keep water fresh and cool. However, when
operating in shallow water where the water is muddy/sandy, the recirculating pump allows you to recirculate and aerate clean water so that
you are not drawing in dirty water that could harm your bait. In the 186BR, the recirculating pump is mounted directly to the aft side of the
livewell. The return from the pump is in the top aft corner of the livewell. The pump is an 800GPH pump and will have an independent
switch and fuse (See Electrical Schematic). The pump will prime itself whenever water is above the intake screen of the pump. To use the
pump, activate the switch. There are no valves to open. Water will begin circulating immediately provided there is enough water in the
livewell. Never run the pump without a sufficient amount of water in the livewell. Running the pump dry for extended periods of time may
damage the pump resulting in failure. Water should be above the inlet screen when using the pump. The recirculating pump can be run in
conjunction with the aft livewell pump to provide increased circulation and aeration, however it is not necessary.
System Operation and Maintenance
When using any of the 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.
