Can the live well and raw water washdown [electrical pumps on a particular Boston Whaler 235 CONQUEST model boat] be operated simultaneously? I am away from the [Boston Whaler 235 CONQUEST] for several days and cannot test. I cannot determine from wiring schematics in the manual if there are separate pumps. The raw water would not come on recently, and I may have had the livewell running at the same time, but I do not recall. I do recall, however, that the red light did came on when I toggled the raw water switch to its ON position.

I know on my 1992 Walkaround they are the same pump.

Please give a link to the electrical schematic diagram. It should be simple to interpret the wiring if it is shown accurately in the schematic diagram.

What year is your Conquest 235? Generally the Conquest models have three water pumps – one for the freshwater supply, one for the livewell and one for the raw water washdown (if the Conquest has AC/Heat there will be a third pump specific to the unit that is raw water). In regards to the raw water pumps (using the Conquest 305 as an example), just above the seacock is the raw water pump that supplies the livewell. Just prior to that, or maybe even on the pump itself, there should be fitting/bypass with a hose that supplies the second raw water pump. This pump is for the livewell and is usually mounted.

I don't understand quite exactly what information is being sought from web readers regarding the Boston Whaler 235 CONQUEST that couldn't be found in the detailed drawings of the various water systems and the electrical system. You can obtain the drawings on-line from the website


and find the details about these systems. For the electrical power distribution and control, for example, I would refer to

as a reference. That drawing shows five separate electrical pumps and how they are controlled.

Just glancing at the schematic diagram, I don't see that there is an electrical interlock wired among the various pumps that would prevent one from being operated when another was. Was that the focus of your initial inquiry?
