Thanks to all who helped with your info, pictures,
specifications and comforting words relative to my recent
sea-chest lid problem. 
The discussion has evolved a bit but
here are my observations:
When flushing my systems with fresh
water I have always used dock or yard water directed at full
force into the open sea-chest.  In my current slip I have
unbelievable water pressure.  With one exception, I have
never been able to keep up with the demand of the Calpeda or
March AC pumps or the Onan or 75 hp Yanmar engines.  No
problem keeping up with the demand of the head pumps and I
long ago did away with the sea water anchor wash down pump
and changed to a fresh water  anchor wash (Joel's
friend, Ray Eaton, now deceased, installed that for me in
Ft. Lauderdale).
The
exception I noted above, was when I once found I was able to
keep up with the Yanmar throughput.  I next checked the
Yanmar impeller and found I was missing three vanes.  So
being able to evaluate how much water is being consumed from
the sea-chest is a diagnostic aid about the health of your
impellers for the engines and other sea water consuming
accessories. 
Thanks
again all,
