I have a question? I have a friend (i know hard to believe). He has a fountain. He sent his boat up north months back. On the way up the transporter ran into a snow storm. The temp dropped to 30 degrees. the transporter pulled over, dumped a few gallons of antifreeze into each sea strainer and cranked the motors. Never strarted them! Got back n the road, drove about 5 hours to the destination where supposably the boat was put inside a heated warehouse. Long story short, now both blocks and 2 heads are cracked. Because the motors were never started and the thermostats never opened the blocks were full of water. My question is, could they have frozen that bad in that short of time in those just below freezing temps while in transport. My opinion is no friggen way, the boat had to be left outside for a period of time in colder temp to do that kind of damage.
This is a huge problem, we need expert advice. We all know how may experts we have on OSO!!
