Hey guys went out in the boat last weeken ran it for a hour at the end lost forward an reverse. Checked volt to coils 12v ohmed them out about 5 to 6 ohms . got it home after being towed in found all the oil gone in lower . The top had some but not a lot. I hear no noise grinding or crunching put oil in an still would not go into gear . Did I burn the shift out in the lower or is there some thing else inside that went out . The motor did not get hot ran 140 to 160 .What do ya'll think .
