I'm having some trouble changing the oil in my OMC 400 stern drive in my '78 sunrunner. There's an oil fill on the top and a few screws that look like oil fills or drins on the side. The oil is coming out very slowly. What I really need to know is how do you drain the oil in the thing and how much does it take to refill. I'd appreciate any help with this.<br /> <br /> Thanks
