Just got a boat with a 1978 55 HP 2 cyl 'Rude on it. Under the cowling the thing is an oily greasy mess with crud everywhere. I guess that is better than a white corroded mess, but it is a mess nonetheless. <br /><br />My question is what is the best way to clean up the goop. I could spray the entire thing with Gunk and then power spray it off. But I suspect there are parts that should not get wet. <br /><br />Any suggestions on the best way to clean the thing without damaging anything?<br /><br />Thanks
