Stus-List Over Heating

[Paul Hood via CnC-List]

I just had an overheating issue on my A4.  Last year I had the Moyer inline
water alarm purchased and put it on to find the flow was significantly
reduced.  I didn't like that so I removed it.  This year, put the boat in
water, opened seacock valve for cooling and this weekend after many days out
already and numerous hours on the motor, the valve seemed to close after an
hour of straight motoring.  It appears the valve closed on its own.  Not
sure how long its been slowing closing itself but I'm sure nothing could
have inadvertently closed it, I'm sure of it.  I suspect the last bit of
movement went the fastest once it hit the almost horizontal position.  The
handle is very smooth and easy to close and I suspect the vibration from the
engine dropped the handle to perpendicular position of the valve.  I will be
putting the alarm back on in short order.  I also put a small tie around the
handle to keep it vertical.  Still very odd as this has never happened
before.

Hi Paul,is the valve a bronze Apollo ball valve?  I'm surprised it moves that 
easily and doesn't leak from the packing...Danny
