Johnson 40 76elr. I drained the oil from the lower unit after I unscrewed both top and bottom screws(plugs). No problem, oil was dark color , no trace of water or metal shavings. But after filling it with fresh oil, I tried to screw the bottom plug back in but it wouldn't go in at all like if something inside came down and closed the whole from inside!!! I tried to push it a little with a screw driver but it would not budge. Does anyone have an idea why this happened? It does not feel at all like metal shaving.
