Is this a weep hole?


Recommended Posts

You can try googling it. On a Mercruiser I/O it is a weep hole from the shift mechanism and that may be the grease/oil you see coming out. Check your lower unit oil if you cant get a answer and see if it milky and or filled to the top. Usually it only holds a quart ,so its not going to cost you much to verify one way or another. My gut feeling is it is residue from the shift linkage.

Thanks bob. I tore it down and cleaned it today looks repairable have to see what the welder thinks about it


I had a lower unit welded,it didn't work and it would have been cheaper to replace the housing to start with. If the crack runs after welding you well lose oil and fill up with water and tear up the gears and leave you dead in the water.
