Long story short I have a 1982 Evinrude 75hp electric start. Replaced the lower unit with a used one (runs fine, but have a lower unit leak) , and have no idea what model this "new" lower unit belongs to. I need new lower unit drain screws, so I took a gamble and just bought the ones that fit my original lower unit (0307551), and they did not fit. These old drain plugs have space (metal with no threads) between the head of the screw and where the threads start, and the threads seem to be of a smaller diameter. The replacements I purchased did not have this space at all, and the only other type that i have turned up is the screws with the skinny magnet protruding from the end.
I have done extensive google image search to try and find the same screw as to what I have, and have came up empty handle, so any help would be greatly appreciated.
