What is this thing, attached to a Mercury KE4 lower unit?

At first I thought it was some kind of home grown patch, but then I noticed that the casting fits the lower unit perfectly. Any ideas what it is, or was?

Long live American manufacturing!

Bill,

Mercury’s are not my thing, outside of the auto tranny models, so I have nothing to offer except curiosity like you!

My first guess is it may be a “repair” for a gearcase with damaged water pump cover threads or damaged case.
Clever native craftmanship NOT
factory. OR maybe something else. You may be in market for an as As made by Kiekhaefer
gear case assembly if you open
this can of worms up.
KE4/Mark 7 are fairly common so parts are out there. Rarest

That is almost definitely not factory to my knowledge, and I highly doubt that any sort of aftermarket part manufacturer would put those non-hydrodynamic u-brackets on their motors unless it is specifically designed for stripped threads.  Probably just a very well made home repair.

MY thoughts it is a hookup for a water hose for flushing.

That would make the most sense, but I do not see anywhere to hook up a hose from the pictures.
