I don't think there are any readily available units that have an onboard "charge pump". You will need a separate water pump to provide water to the pressure washer high pressure pump. I've done this myself with a 1/3 hp electric water pump running from a generator and feeding water to a gas powered pressure washer. Pressure washers are not high flow units, typically ~3-5gpm, so you don't need a huge pump to feed it. A small 1" gas powered pump will do, or a 1/3-1/2hp electric submersible utility pump.
Since you've eliminated everything else, I guess you want one that uses bottled water.
Can you do it without contaminating the lake water? Best check local regulations to be sure.
