I have one of those quick drain sump drain plugs on my C-85 engine and I'd like to replace it with a simple plug. I believe the sum plug is a standard 7/16 bolt drilled for safety wire. My quick drain plug is not causing a terrible loss of oil but it's dripping just enough to cover my right side bungee boot. Does anyone have a suggestion? I'm having trouble finding the original manufacturer of the sump drain plug. My only reason for wanting the original part number is to be able to use the number to cross-reference to other manufacturers. I have no need to quick drain my oil. I can do it the old fashioned day when my Hobbs says it's time. John
