Ok... I have been trying to figure this out for awhile. My S299 is sitting at the dock so I cannot just dump cleaning chemicals into the lake! I asked the local svc center to give me a quote to powerwash it out and install my new motor and it came to $4k. Too rich for me. I am capable of installing the diesel however I really would like to powerwash the crap out of the engine compartment and repaint it. Make it easy to see oil leaks as well as getting rid of the smell. The boat wreaks of diesel!! It had a rotted tank that I am also replacing. So any ideas, is there anyway to filter the bad stuff out of the bilge and pump the rest overboard? Folks I am desperate!!
