What I have is a stripped lower unit off a 15 hp Johnson outboard. Nominal 16 x 14 x 6 inches. Aluminum. What I want to do is soak the lower unit in diesel/kerosene rather than buy a parts washer and blah blah. I have three outboards total, one with a blown up power head, one with a cracked midsection and one with a questionable lower. I need two servicable OMC 15s by spring, his and hers as it were. I have a 1976, a 1988 and and a 1993 If I can find the right plastic sheet I should be able to build a custom cardboard container and get all three lower casings soaked clean without having to buy a 55 gallon drum of diesel. Black lawn and leaf bags? Regular white plastic household trashbags? My best idea so far is to grab a new fangled mil-spec Jerry can, they make them out of plastic now, cut the top off and jam a lower case down in there. I don't like it. I can likely get a stripped lower case in and out of the kerosene bath in a week, clean. I don't need something permanent, but I don't want my raspberries tasting like petroleum either. Been to three estate sales lately looking for a container. Nada. Open to ideas.
