Has ANYBODY ever had freeze damage with a Yamaha jet boat?

@Seadeals had the same thing happen to him. I don't think it was freeze related. Perhaps he will add to the conversation.
My boat spent life only in North and South Carolina and has lived in a heated garage throughout my ownership. Freeze damage is possible but highly unlikely. I am 100% convinced it was a weakness in the block casting process/metal circa 2006 as the cracks always seem to follow that casting line. Once it starts, the thermal cycling and water cooling at the crack can open it up quickly. I unfortunately can’t define “quickly” in hours or cycles; but advise catching it early is a must if a repair is attempted.
