If you've scrubbed all the hard surfaces, and the smell persists then either you've got a continuing (albeit unfound) leak such as Denise suggests, or the odour has permeated the upholsterv and/or the headliner fabric, if present.
Does the odour get stronger when running, or is it just generally there all the time? If it varies then chances are you've got a leak somewhere on the pressure side of the fuel system - the diesel may well evaporate eventually and be difficult to spot (eg a soft return line hose, or a poorly fitted injector line fitting...)
If you haven't already, take all the upholstery out of the boat, scrub it (the boat) all down and see if the smell moves with the cushions.
