I've a few inches of oily water sitting in the bottom of my engine compartment, and have had since I bought the craft. I've tried several times to get shot of it, but the bilge pump I have fixed down there always leaves a couple of inches at the bottom, and getting down there with a brush, a scoop and some washing-up liquid is a thankless task.
I've got some bilge and hull cleaner on the way from www.miracleleisureproducts.co.uk, but to go with this I wonder if anyone out there can recommend a good portable bilge pump which would serve as a hoover to get the oily grime of of there, minimising my miseraable afternoons with a bad back?
