Have an '87 Merc 5.7 w/ Alpha One.....Small weep hole (cavity) on lower unit is blocked. I tried to snake it out with paper clip, wire, etc. - No luck. Got a lite on it and it looks like its just a recess that is metal and has no access to cavity - blocked.
During some shifting maintenance a few years back, mechanic said lower and upper unit paint didn't match, possibly aftermarket lower unit added by PO. Has been working fine since '08, still works fine, but on "summerize" inspection today there is no water coming out w/ muffs. Did some aftermarket units have non-functional passage, just a recess / hole with no function. I tried a punch (softly) even and it appears I am hitting metal 1/8" deep?
Anyone seen this? Safe to drill out? What's risk? Whats behind it?
