i was floating in the water, and noticed that there was an oil slick floating behind my boat. also, some brown blobs floated up around the outdrive. back at the dock, i backed the boat in the water, and the oil/grease seems to be coming from the lower steering pivot point. i use Pennzoil marine grease. anyone had this happen? this was not a small amount of oil/grease. there are small blobs of grease on the outdrive that look like the Pennzoil. have i busted a seal?
