And down she goes again

The skimmer was out on a trial run today and it took just over an hour for the same pump to blow as always. Maintenance said it also might be a cotter pin (they call it a key) but they don't go without some serious stresser. The same side as last time blew.
Back in the shop to continue to try to nail this down before the algae and weeds really start to take off.
