1987 Mercury 45 hp Classic 50
1987 Mercury 45 hp Classic 50 is dripping thick black oil from behind prop. After removing prop found oil only to be on the bottom. Top and sides were perfectly dry and free of oil. It has never dripped before and I was wondering if a long day of trolling at idle speeds may have caused this. Do I need to be concerned or is this normal??
