The aqua air controls ( like the cruisair) will show loop temp by holding down up and down button. Took the boat of the sock for an hour without issue. I think the new pumps did the trick. The wiring on the loop pump was corroded and charred. It could have been the culprit. I’m sending the old pumps to depcopump for rebuild as spares.
I doubt it was related to "electrical" versus "cooling water". Chillers are very sensitive to their need for cooling water. Keep that system clean and in good shape.
