Still no working engine

The DOWN BEAT GOES ON, New block was installed ,they fired it up and it ran 15 seconds and locked up and they are now back with Evinrude Technical people trying to get some explanations. So I will call in morning and see what the next step is.
Not all that upset with water temps in mid 70’s up but I will be if this isn’t fixed soon
This is longest I have been off the water in 15 years
