I have a 1986 omc 3.0 cobra with omc outdrive. i was running my engine and noticed a small vent type hole located on the water pump housing. i removed and replaced the impellar, sealed everything up and water is still being seen coming out that little hole on the left side of the water pump housing. the engine does not overheat. but once i replace the cover back on, i am seeing water seeping through the cover because of the little hole. is this normal??? i noticed that this is the original water pump housing from 1986. the hole is not a crack or anything like that. the hole is too perfectly round. any help on this would be appreciated.....
