I have a 175 hp fast strike johnson that is 13 yrs old. I have noticed that there is a small amount of oil coming from where the shaft from the motor meets the top of the lower unit. It has a neoprene hose that comes from the motor to the lower unit @ this same location that could be the cause however, I think it is probably a seal or something up in where the shaft is that is leaking.Other than this leak , this has been a really good reliable motor! Any ideas?
