I recently purchased a 1967 SRV170 with a 120HP Mercruiser. The flush plug is missing and it does not seem to be a threaded hole unless the threads are just gone. Will it hurt the outdrive to run without it? I have read where the plug is not needed if the water pump is updated, but I do not know if it has been. It does not seem as though a plug would go into the existing water pump as the hole where the plug goes is blocked a short way in by a piece of aluminum colored metal, in other words, no hole in the water pump where a plug could go. Hopefully someone can help me here. Thanks, Mike.
