[C320-list] Running engine with seacock off?

[Graeme Clark]

Looks like Lady Luck was on my side
Pulled the hose between the manifold and muffler. No evidence of charring or delamination and it retains flexibility.   I will replace it as a precaution but it’s actually rather a difficult size to procure locally here in UK so I’ll get a length via mail order

Likewise the impeller which was intact with no “flats” on the tips of the blades which I would have expected had it run super hot

My guess is there was enough water in the system that wouldn’t all get pumped out due to air locks, to keep it lubricated and cooked for the few minutes it was running

But I’ll replace it anyway

Fortunately the winds were favorable for a reach I put my wife on the helm and determine something had blocked the seacock to the point when I opened it with the strainer removed it only gave a trickle of water. I scavenged my lockers trying to figure out a way to un block the offending  lack of water. First I try my shop vacuum blowing and suctioning . Still just a trickle. Finally I found a large electrical tie and forced it through the opening twisted it around and dislodged the blockage. I reinstalled the strainer and all is well. after 20 years with the boat it’s the first time this has happened. We would have been upset too say the least if we had caused damage to our only 80 hours old  Volvo penta.
