I recently bought an old Merc, then I bought a manual.  I've been
checking over everything and giving it a tune-up prior to taking it
out.  My book covers a lot, but doesn't say how much water should be
coming out the tell-tale stream ("pisser") if everything is working
properly.

My motor is a 1967 Mercury Model 60 (6.0 horsepower).  There isn't a
hose hooked up to the "pisser", there's just a hole in the leg.  The
diameter of the hole is between 3/32" and 7/64", and it comes out at
around 30 degrees from vertical.  When the motor is running, it just
kind of trickles out, sometimes running down the leg and sometimes
lifting off the leg a bit. Neither motor RPM nor gear (F/R/N) don't
appear to make much difference to the flow rate.  It looks like less
flow than I would expect to see, but I don't know how much it should
be.  I took the lower unit off and checked out the impeller, which
appears to have been recently replaced.  However, the copper tube that
connects the water pump to the powerhead is a bit banged up on the end,
and the seals where it attaches to the water pump don't look that hot
either.  I haven't checked in to getting replacements for the seals or
the impeller yet, and I haven't tried flushing out the cooling system
with a hose.  Should I be worried, or does it sound like I have enough
tell-tale flow?

Thanks!

Dave.
