The Marine hull cleaners I used were On & Off marine hull cleaners by Marykate ?, and Star Brite marine bottom & hull cleaner. The Star Brite seemed stronger than the On & Off, nut may heave been because it had been on the shelf longer. If anyone is considering this method, clean as much of the oily sludge off the part, and caked grime in corners 1st, do it outside in a well ventilated area, stay upwind, wear gloves & eye protection, and have a fresh water hose handy. You will probably like the results, but not the process. Takes about 2 hours all tol
