The problem showed up (water in oil,
hydrolocked with water in pistons 5 & 7) in late July in Texas after
putting
many hours on it since "winter" (we had a mild winter last year and even
if I
forgot to drain it, I don't think it got cold enough to freeze under the
boat
cover, under the padded motor cover).

Being covered or under a padded box will only slightly slow the ambient
temperature from reaching the block.

If it was 30 degrees out for any length of time, your block was 30
degrees...period.
