Pressure Washer

Essentially a pump with a pressure shutoff switch and some hoses, this came loose in a fairly sturdy plastic case so I mounted the gubbins more permanently, added an on/off switch and put in a ciggie-lighter socket so it works as a fairly bulky 12V extension lead. It's tamed by bungying to the safety lines, dropping the intake into the ocean, plugging in and operating the trigger hose fitting.

Internals - what it looks like when you open up the case.

The closed portable shebang.
